The Legacy of the D6T Series
Caterpillar’s D6T dozer, particularly the XW variant, represents a pivotal evolution in mid-size track-type tractors. Introduced in the late 2000s, the D6T replaced the D6R with a focus on electronic integration, emissions compliance, and operator comfort. The D6T XW (Extra Wide) model features a wider track stance for improved flotation and stability, especially in soft ground conditions. By 2015, Caterpillar had sold tens of thousands of D6T units globally, with strong adoption in forestry, mining, and civil construction.
The D6T’s hallmark is its integration of multiple electronic control modules (ECMs), including the Powertrain ECM, Implement ECM, and Monitoring System. These modules communicate via Controller Area Network (CAN) lines, allowing real-time diagnostics, adaptive shifting, and load-based engine response. However, this complexity also introduces new failure modes—like fault code 596-9.
Understanding Fault Code 596-9
Fault code 596-9 is a diagnostic trouble code (DTC) that indicates a loss of communication between the Monitoring System and the Implement ECM. In Caterpillar’s CID/FMI format:

• CID 596: Implement ECM communication
  
• FMI 09: Abnormal update rate or no response
  

• Flickering gauges and dash lights
  
• Audible alarms
  
• Spontaneous shifting to neutral
  
• Faults appearing even with engine off and key on
  

• Engine ECM
  
• Implement ECM
  
• Powertrain ECM
  
• Monitoring System
  
• Transmission ECM (in some models)
  

• Inspect all ECM connectors for corrosion or loose pins
  
• Measure resistance across CAN lines (should be ~60 ohms total)
  
• Use an oscilloscope to check waveform integrity
  
• Confirm grounding continuity between ECMs and chassis
  

• Avoid pressure washing near ECM connectors
  
• Use dielectric grease on terminals during service
  
• Train operators to report flickering gauges or alarms immediately
  
• Schedule annual CAN line inspections, especially on rebuilt or flood-damaged machines

Replacing a hydraulic cylinder on heavy equipment, particularly in situations where you might expect to bleed air, can often seem more complicated than it is. One common question many operators face is whether they need to bleed the system after replacing a cylinder. While traditional methods may dictate that bleeding the system is necessary to remove air and prevent damage, modern equipment and proper techniques show that this step may not always be required. This article dives into the reasons behind this, offering insights into hydraulic systems, cylinder replacement, and how to approach this task with minimal hassle.
Hydraulic System Basics
Before addressing whether air bleeding is necessary, it’s essential to understand how hydraulic systems work. A hydraulic system uses fluid to transmit force throughout various components, such as hydraulic cylinders, pumps, and valves. These systems rely on fluid pressure to perform mechanical tasks, from lifting loads to powering other equipment movements.
Air trapped in the hydraulic fluid can cause several issues, such as erratic movement, delayed response, or even potential damage to the system. Bleeding the air from a system traditionally ensures that these issues are avoided, but modern equipment is designed to handle some air presence without substantial operational disruptions.
The Cylinder Replacement Process
When replacing a hydraulic cylinder, the focus should be on ensuring the correct installation and function of the new cylinder, rather than stressing over air removal. The steps typically involved in the process include:

1. Removal of the Old Cylinder: Before installing the new one, ensure the old cylinder is properly removed. This involves relieving pressure from the system, disconnecting hoses, and unbolting the cylinder from its mounts.
   
2. Installing the New Cylinder: Once the old cylinder is out, the new one is installed by aligning it properly and ensuring all connections are tight. Be sure to use new seals and check for any wear and tear on the equipment to avoid future leaks.
   
3. Reconnecting the System: After installing the new cylinder, reconnect the hydraulic lines. At this point, the system may appear to have air in it, but in most cases, this air doesn’t pose a major issue.
   

1. Self-bleeding Cylinders: Many modern cylinders are designed to self-bleed. This means that even if air is trapped in the system, it can escape through vent valves or naturally within the system as pressure is built up. This design minimizes the need for manual bleeding.
   
2. Automatic Venting: Hydraulic systems in many new machines have automatic venting systems that help to expel air as the system is pressurized, ensuring that air doesn’t become a significant issue. These systems eliminate the need for manual air removal after a cylinder replacement.
   
3. Small Air Pockets: Even if air does remain in the system, small air pockets don’t always cause issues. The fluid can often push out minor air pockets as the system operates, without requiring a lengthy bleeding process. It’s usually the larger, more persistent air pockets that need attention.
   
4. Modern Hydraulic Fluids: With advancements in fluid technology, hydraulic fluids have become more efficient at handling air. New formulations of hydraulic oil, for example, are designed to allow air to escape more easily without affecting system performance. These fluids help prevent cavitation, erratic movements, and damage to the system.
   
5. Pressure Build-Up: As the hydraulic system is used and the pressure is applied, any trapped air tends to rise to the top of the system. This gradual pressure process allows air to vent without needing a separate bleeding procedure.
   

• Severe Air Entrapment: If large amounts of air are trapped in the system, bleeding may still be required. This can occur if the system is opened up significantly, such as when both the cylinder and the hydraulic lines are disconnected for maintenance.
  
• New Equipment or Full System Replacement: When dealing with new equipment or after a complete hydraulic system replacement, there might be a need for bleeding if the system isn’t designed to self-vent properly or if the fluid level is too low.
  
• Erratic Movements or Delays: If you notice that the system behaves erratically, with delayed movements or a sluggish response, then manual bleeding may be necessary to remove air pockets that are affecting system performance.
  

1. Start the Engine: Begin by starting the engine and allowing the hydraulic system to build pressure. Ensure all valves are in their proper positions.
   
2. Operate the System: Cycle the hydraulics several times to move the system through its full range of motion. This helps to release air bubbles from the fluid and pushes them toward the venting system.
   
3. Check for Air Bubbles: Check the hydraulic fluid reservoir for air bubbles. If you see air bubbles, operate the equipment further to ensure they are expelled.
   
4. Check the Vent Valve: Many systems have vent valves designed to release air. Open these valves carefully to allow the air to escape.
   
5. Monitor the System: After bleeding, continue to operate the system while checking for any unusual noises or performance issues. If the problem persists, you may need to inspect the seals or check for additional issues with the system.
   

The Challenge of Frozen Terrain
Operating heavy equipment in icy or frozen ground conditions presents a unique set of challenges. Standard track pads on dozers and forestry machines often struggle to maintain traction on slick surfaces, especially when climbing grades or pushing loads. In regions like the Pacific Northwest, Alaska, and northern Canada, winter operations demand specialized solutions to prevent slippage, reduce wear, and improve safety.
Historically, operators have resorted to welding hardened steel bars—known as “ice lugs” or “corks”—onto the grousers of their machines. These protrusions bite into frozen ground, providing the grip needed to maneuver through snow-covered slopes, icy logging roads, and compacted frost layers.
Traditional Weld-On Ice Lugs
The classic method involves cutting two-inch sections of hardened steel and welding them directly onto the track grousers. This labor-intensive process can take several hours per machine, especially on large dozers like the Caterpillar D9. Each operator often performs their own welding, particularly in small logging outfits where mechanics are scarce.
Advantages:
• Customizable lug placement and size
• Maximum grip tailored to terrain
• Low upfront cost if steel is sourced locally
Drawbacks:
• Time-consuming installation and removal
• Risk of cracking or damaging track pads during welding
• Annual rework required due to wear and breakage
One logger in Montana recalled spending entire weekends welding corks onto his feller buncher before the snow season hit. While effective, the process consumed valuable time and resources.
Bolt-On Track Claws and Quick-Connect Systems
In recent years, bolt-on traction aids have gained popularity. Products like Montana Track Claws offer a modular alternative to welding. These devices bolt through the clean-out holes in the track pads, allowing for quick installation and removal without damaging the base metal.
Benefits of bolt-on systems:
• Reusable across multiple seasons
• Faster installation—often under two hours per machine
• Reduced labor costs and downtime
• No welding required, preserving pad integrity
Operators report that while the initial investment is higher, the long-term savings in labor and steel make bolt-on claws more economical. One contractor estimated that switching to bolt-on claws saved him over $3,000 in welding costs across two winters.
Design Innovations and the Rise of CORKS
A new generation of traction devices is emerging, including a product called “CORKS,” designed for smoother ride quality and better penetration in frozen ground. Developed by a certified welder in Montana, CORKS aim to improve upon traditional ice lugs by offering a more ergonomic profile and enhanced durability.
Key features under development:
• Rounded edges to reduce vibration
• Hardened alloy composition for longer wear life
• Modular mounting options for different pad styles
• Improved ground contact geometry for icy slopes
While still in prototype stages, CORKS represent a shift toward engineered traction solutions that balance performance with operator comfort.
Installation Tips and Best Practices
Whether using weld-on lugs or bolt-on claws, proper installation is critical to performance and safety.
Recommendations:
• Clean track pads thoroughly before installation
• Use grade 8 bolts and lock washers for bolt-on systems
• Space lugs evenly to prevent imbalance and vibration
• Avoid placing lugs near pad hinges or wear points
• Inspect lugs weekly for loosening or damage
For weld-on setups, preheating the pad and using low-hydrogen rod can reduce cracking. Bolt-on systems should be torqued to spec and checked after the first few hours of operation.
Terrain-Specific Strategies
Different environments call for different lug configurations:
• Logging roads: Medium-height lugs spaced every third pad
• Steep slopes: High-profile lugs on every pad for maximum grip
• Frozen clay: Wider lugs with serrated edges for penetration
• Urban snow removal: Low-profile claws to reduce surface damage
Operators in British Columbia often use hybrid setups—weld-on lugs on the outer pads and bolt-on claws in the center—to balance traction and maneuverability.
Conclusion
Ice lugs and track claws are essential tools for winter operations in frozen terrain. While traditional weld-on methods remain effective, bolt-on systems and new innovations like CORKS offer faster, safer, and more cost-efficient alternatives. By choosing the right traction aid and installing it properly, operators can extend machine life, reduce downtime, and maintain productivity even in the harshest conditions. As winter equipment technology evolves, so too does the art of gripping the ice.

The Rise of the Used Equipment Market
In the wake of rising new equipment prices and tighter capital budgets, the used construction equipment market has become a lifeline for small contractors, farmers, and municipalities. Brands like Caterpillar, Case, John Deere, and Kubota have long dominated the new sales charts, but their older models—especially those from the 1990s and early 2000s—are now in high demand. According to recent auction data, used backhoes, compact excavators, and skid steers have seen price increases of 15–25% over the past five years, driven by supply chain delays and Tier 4 emissions complexity in newer machines.

The EX50URG and Hitachi’s Compact Excavator Lineage
The Hitachi EX50URG is a compact hydraulic excavator designed for urban utility work, landscaping, and small-scale construction. Produced in the late 1990s and early 2000s, it was part of Hitachi’s URG series—machines built with zero tail swing and compact dimensions to navigate tight job sites. Hitachi Construction Machinery, founded in 1970, had already established itself as a global leader in precision excavators, and the EX50URG was one of its most popular mini models in Japan and Southeast Asia.
Powered by a 3-cylinder diesel engine, typically a Yanmar or Isuzu variant depending on market, the EX50URG was known for its fuel efficiency, smooth hydraulics, and ease of transport. However, as these machines age, they often develop performance issues that require careful diagnosis.
Symptoms of Power Loss and Black Exhaust Smoke
A common issue with older EX50URG units is sudden power loss accompanied by thick black smoke from the exhaust. This combination points to incomplete combustion—where diesel fuel is injected but not fully burned. The black smoke is unburnt fuel, and the lack of power suggests that the engine is either over-fueling or under-airing.
Key terms:
- Incomplete combustion: Occurs when fuel is not fully burned due to poor air-fuel mixture, low compression, or injector malfunction.
- Black smoke: Typically indicates excess fuel or insufficient air, often caused by clogged air filters, faulty injectors, or turbo failure.
- Power loss: A drop in engine output, often linked to fuel delivery, air intake, or timing issues.
In the EX50URG, these symptoms often appear suddenly, even if the machine starts easily and idles smoothly.
Injector Wear and Part Sourcing Challenges
One of the most likely culprits is injector malfunction. Over time, diesel injectors can wear internally, leading to poor spray patterns, delayed injection timing, or excessive fuel delivery. In a 3-cylinder engine, even one faulty injector can throw off the entire combustion cycle.
Operators seeking replacement injectors often face difficulty sourcing part numbers, especially for Japanese domestic models. The EX50URG may use proprietary injectors not listed in Western catalogs, requiring direct contact with Hitachi or Yanmar distributors in Japan.
Recommendations:

• Remove and bench-test all three injectors for spray pattern and pressure
  
• Replace with matched OEM injectors or high-quality aftermarket equivalents
  
• Use copper washers and torque to spec to prevent compression leaks
  
• Clean injector seats and inspect for carbon buildup
  

• Remove and inspect air filter for dust, oil, or water contamination
  
• Check intake hoses for cracks or collapse under vacuum
  
• Inspect turbocharger (if equipped) for shaft play or oil leakage
  
• Clean intake manifold and verify unobstructed airflow
  

• Use a multimeter to test voltage at the fuel solenoid during startup and operation
  
• Inspect sensor connectors for corrosion or loose pins
  
• Check grounding points near the battery and engine block
  
• Scan for fault codes using a compatible diagnostic tool
  

• Remove injectors and install compression gauge
  
• Crank engine and record peak pressure for each cylinder
  
• Compare readings to factory specs (typically 350–450 psi for small diesels)
  
• Investigate low readings with leak-down test or bore inspection
  

• Replace air and fuel filters every 250 hours
  
• Use high-quality diesel with proper cetane rating
  
• Inspect injectors every 1,000 hours or if symptoms appear
  
• Clean intake and exhaust paths annually
  
• Monitor oil consumption and check for blow-by at the breather
  

Building a motocross track might seem like an exciting venture for motocross enthusiasts, but it’s essential to understand the multiple challenges that come with creating a professional-quality track. From construction costs to environmental factors, the obstacles involved are more than just physical labor and dirt. Whether you're a hobbyist or looking to start a more competitive setup, there are several critical points to consider before diving into the project.
High Initial Construction Costs
One of the first considerations when building a motocross track is the substantial financial investment required. Constructing a track that is both safe and challenging involves more than just laying down some dirt. For a track to be effective and long-lasting, proper materials must be sourced, and significant labor is required to shape the land, create jumps, berms, and other track features.
The equipment needed for the job can also be costly, especially if you're not already equipped with bulldozers, graders, or other earth-moving machinery. While some might think of doing it with lighter equipment, heavy-duty machinery is typically necessary to ensure the track is properly designed and constructed. Labor costs, whether it’s hiring professionals or relying on friends and family, also add up quickly.
For many people, these initial costs can be prohibitive. Moreover, maintaining the track over time requires ongoing expenditures, including regular grading, replenishing dirt, and keeping up with repairs due to wear and tear.
Land Use and Environmental Concerns
The next major consideration is finding the right location. A good motocross track requires a relatively large area of land, often upwards of 10 acres or more. This land needs to be both flat enough to allow for track creation but also needs to be able to drain well to prevent waterlogging after rainstorms. Many potential locations have environmental concerns that can make construction difficult.
In urban or suburban areas, zoning laws might prevent the construction of a motocross track altogether, making it a legal headache. Even in rural areas, there could be issues such as soil quality, access to utilities like water, and the environmental impact of disrupting natural habitats.
Building a motocross track near residential areas can lead to complaints about noise, dust, and safety concerns, which often results in pushback from neighbors or local authorities. In some cases, a local zoning board might not approve the track, forcing the project to be scrapped entirely.
Track Design Challenges
Creating a challenging but safe track requires both technical skill and knowledge of the sport. A good track needs to offer a variety of obstacles, such as jumps, berms, tabletops, whoops, and rhythm sections, all while being safe for riders of various skill levels.
Track layout is essential. The dirt needs to be shaped in a way that offers smooth transitions and safe landings, and the angle and placement of jumps require expert knowledge of how dirt bikes interact with different types of surfaces. Poorly designed tracks can lead to crashes or a lack of flow, which detracts from the overall experience for riders.
Too often, people attempt to build tracks with only a vague idea of how to design obstacles or how to manage the speed and flow of the riders. Miscalculating the track's features can lead to significant safety issues or make the track much less enjoyable.
Maintenance Requirements
Once the track is built, maintenance becomes an ongoing responsibility. A motocross track, unlike a traditional dirt path or park, needs to be frequently reshaped to keep it safe and challenging. Dirt can get displaced over time, especially after heavy use or bad weather, requiring constant attention to smooth out ruts, fill in holes, and ensure jumps remain in proper condition.
A major part of maintenance is also ensuring proper drainage. Motocross tracks can quickly turn into muddy, impassable pits if rainwater isn’t channeled away effectively. Without proper drainage systems in place, the track can become unrideable during or after rainstorms, which leads to frustration and loss of investment.
Moreover, regular grooming of the dirt and upkeep of the equipment are necessary for keeping the track in top condition. As with any outdoor project, a motocross track is subject to natural wear and tear, meaning its longevity is only as good as the effort put into maintaining it.
Safety Concerns
While motocross is an exciting sport, it’s also one of the more dangerous outdoor activities, requiring the rider to be both skilled and cautious. A track that is poorly designed or maintained increases the risk of accidents significantly. Track features, such as jumps or tight corners, need to be well thought out to prevent injuries.
An improperly constructed jump can lead to a dangerous landing, increasing the risk of serious injury or worse. The angles, height, and landing zones of jumps should be tested and perfected to ensure a smooth, safe experience. Without this attention to detail, a fun sport can quickly turn into a dangerous pursuit.
Additionally, safety equipment like proper fencing, safety barriers, and clear track markings should be considered to protect both riders and spectators. Any track, no matter how well-designed, needs to prioritize rider safety, which can be an added cost and ongoing concern.
Liability and Legal Issues
Another significant issue that many people overlook when building a motocross track is the potential liability. If someone gets injured on your property, you could be held responsible for medical bills, legal fees, and more. In the worst-case scenario, this could lead to costly lawsuits and a tarnished reputation.
To mitigate these risks, insurance is a must. However, securing insurance for a private motocross track can be difficult and expensive. Some insurance companies may refuse coverage entirely due to the inherent risks of the sport.
If you're running a track that allows others to use it, you’ll also need to draft waivers and ensure that all riders sign them before participating. These legal documents don’t guarantee that you won’t be sued, but they can provide some level of protection if an injury occurs.
Alternatives to Building a Motocross Track
Given the financial, legal, and logistical challenges associated with building a motocross track, it’s worth considering alternatives. Joining an existing motocross club or renting time at a local track can provide the same benefits without the burdens of construction and upkeep. Many regions have motocross parks or tracks that allow riders to pay for daily access, providing a well-maintained environment without the headache of ownership.
In some areas, it may also be possible to lease or share land with others who are interested in building a track. Shared costs and responsibilities make this a more feasible option for many motocross enthusiasts.
Conclusion
While building a motocross track can be an exciting project, it’s not without its challenges. The high construction costs, land use concerns, environmental factors, and safety requirements all make it a difficult undertaking. For those who are passionate about motocross and have the resources to overcome these obstacles, building a track can be rewarding. However, it’s crucial to thoroughly evaluate the financial, legal, and practical aspects before embarking on such an endeavor. If these challenges prove too great, finding alternatives through established tracks or shared projects might be the best way to enjoy the sport while minimizing risks and costs.

The Volvo EC210LC and Its Electrical Architecture
The Volvo EC210LC hydraulic excavator, introduced in the early 2000s, was part of Volvo Construction Equipment’s push into the mid-size excavator market. With an operating weight of approximately 21 tons and powered by a Cummins 5.9L diesel engine, the EC210LC was designed for versatility in earthmoving, demolition, and utility trenching.

Kill Switch Failure and Diagnostic Challenges
A common issue reported by operators involves the kill switch failing to shut down the engine, even after replacement. This failure can be particularly concerning in emergency scenarios where immediate shutdown is required. The switch itself may be functional, but if the underlying circuit is compromised, the signal won’t reach the fuel shutoff solenoid or electronic control module (ECM).
Key terms:
- Kill switch: A manual or electronic device that interrupts fuel or ignition to stop the engine.
- Fuel shutoff solenoid: An electrically actuated valve that cuts fuel flow when de-energized.
- ECM (Engine Control Module): The computer that manages engine parameters and receives input from control switches.
In the EC210LC, the kill switch typically sends a signal to the ECM, which then deactivates the fuel solenoid. If any part of this chain is broken—due to wiring faults, connector corrosion, or ECM failure—the engine will continue running.
Electrical Pathway and Common Failure Points
The kill switch circuit includes several components:

• Kill switch itself (momentary or latching)
  
• Wiring harness from switch to ECM
  
• ECM logic and output signal
  
• Fuel shutoff solenoid mounted on the injection pump
  

• Test continuity from switch to ECM using a multimeter
  
• Verify voltage at the solenoid when the switch is activated
  
• Inspect connectors for corrosion, bent pins, or loose sockets
  
• Check ECM output using a scan tool or voltage probe
  

• Disconnect power and observe whether the engine shuts down
  
• Manually depress the solenoid plunger to verify movement
  
• Listen for clicking sound when power is applied or removed
  
• Remove and clean the solenoid if sticking is suspected
  

• Reflashing ECM firmware if updates are available
  
• Replacing ECM with a remanufactured unit
  
• Installing an independent kill circuit that bypasses ECM logic
  

• Inspect wiring harnesses quarterly for wear and abrasion
  
• Seal connectors with dielectric grease to prevent corrosion
  
• Test kill switch function during regular maintenance checks
  
• Keep spare solenoids and switches on hand for field replacement
  
• Train operators on manual shutdown procedures in case of failure
