In the world of heavy machinery, maintaining the driving tracks and associated systems is crucial for ensuring longevity, efficiency, and optimal performance. This is especially true for tracked equipment, such as bulldozers, excavators, and certain cranes, which rely on a system of tracks driven by motors (often referred to as "Boggs motors" in certain industries). This article delves into the importance of driving tracks and Boggs motor systems, common issues faced by operators, and practical solutions for maintenance and troubleshooting.
Understanding Driving Tracks and Boggs Motors
Heavy equipment that uses tracked undercarriages relies on a robust set of systems to ensure movement across various terrains. The driving tracks are powered by specialized motors, often hydraulic in nature, which provide the necessary force to move the tracks and propel the equipment.
A Boggs motor, or track drive motor, is a key component in many tracked vehicles. It is responsible for transmitting power from the engine to the track system, allowing for efficient movement of the equipment. The motor is connected to the track sprocket and drives the rotation of the tracks. As such, any malfunction or degradation in the performance of the Boggs motor can lead to significant operational issues, including reduced mobility, uneven wear on the tracks, and even complete operational failure.
Components of the Track Drive System

1. Track Drive Motor (Boggs Motor)
   The heart of the track drive system, this motor provides the power necessary to rotate the sprockets and propel the tracks. The motor typically uses hydraulic power, but some systems also incorporate mechanical drives. Depending on the design, these motors may be mounted directly on the undercarriage or housed within the chassis.
   
2. Track Sprockets
   These are the large gears that mesh with the track links. The driving motor transmits power to these sprockets, which then engage with the track to initiate movement.
   
3. Track Links
   The individual components that form the continuous loop of the track. Track links are connected to each other by pins, and they engage with the sprockets to create forward motion.
   
4. Idler Wheels and Rollers
   These components help guide the tracks around the sprockets and ensure smooth movement. Idlers are located at the front of the track system, while rollers provide support throughout the track length.
   

1. Hydraulic Leaks in the Motor
   Hydraulic systems are susceptible to leaks, and a Boggs motor is no exception. Leaks can cause a loss of hydraulic fluid, which in turn affects the motor's ability to deliver adequate power to the track drive system. This can result in poor performance, such as slow or uneven track movement.
   • Solution: Regularly check the hydraulic fluid levels and inspect hoses and seals for any signs of leakage. Repairing these leaks promptly will help prevent further damage to the motor and the system.
     
2. Clogged Hydraulic Filters
   The hydraulic system in track-driven equipment relies on clean fluid to function efficiently. Clogged hydraulic filters can restrict the flow of fluid to the motor, leading to poor performance, overheating, and potential damage to internal components.
   • Solution: Regularly replace hydraulic filters as part of routine maintenance. Make sure to follow the manufacturer's recommended replacement intervals to avoid issues with fluid contamination.
     
3. Excessive Wear and Tear on Tracks
   Tracks that are not properly tensioned or that suffer from misalignment can experience excessive wear. Over time, the misalignment of tracks can put added stress on the driving motor, leading to further degradation of the system.
   • Solution: Properly adjust the tension of the tracks and inspect them for wear. Regularly check the alignment to ensure the tracks are running smoothly and evenly.
     
4. Overheating of the Motor
   Overheating is a common issue that affects many hydraulic motors, including those in track drive systems. When the motor runs too hot, it can cause seal degradation, fluid breakdown, and eventual motor failure.
   • Solution: Ensure that the cooling system is working efficiently and that the hydraulic fluid is at the proper temperature. Monitor the temperature gauges closely and avoid pushing the system beyond its recommended limits.
     
5. Motor Seal Failures
   Over time, the seals in the track drive motor can wear out, leading to internal leakage and a loss of hydraulic pressure. This can cause erratic performance, including jerky movement or complete failure of the motor to function.
   • Solution: Periodically inspect the seals and replace them as part of regular maintenance. Keep an eye on fluid levels and any signs of a drop in performance, which could indicate seal failure.
     

1. Regular Inspection and Cleaning
   Schedule regular inspections to look for signs of wear, damage, or leaks in the track system and motor. Cleaning the motor and related components regularly can also prevent dirt and debris from building up, which can hinder performance.
   
2. Lubrication
   Proper lubrication of moving parts, such as the rollers, sprockets, and track links, is essential to reduce friction and prevent excessive wear. Make sure to follow the manufacturer's lubrication guidelines to keep the system running smoothly.
   
3. Track Alignment and Tensioning
   Check the alignment and tension of the tracks regularly. Misalignment or improper tension can lead to uneven wear on the tracks and the motor. Adjust the tension according to the manufacturer's specifications.
   
4. Hydraulic System Maintenance
   Keep the hydraulic fluid clean by replacing the filters at the recommended intervals. Additionally, check the hydraulic hoses and fittings for leaks or signs of wear, and replace them as necessary.
   
5. Monitor Operational Temperature
   Track drive motors should operate within a specified temperature range. Keep an eye on the temperature gauge and ensure the cooling system is functioning properly to prevent overheating.
   

1. Check for Hydraulic Leaks
   Inspect the motor and hydraulic lines for any visible signs of leaks. If fluid is leaking, replace seals or hoses as necessary.
   
2. Test the Motor’s Hydraulic Pressure
   Use a hydraulic pressure gauge to test the output pressure from the motor. If the pressure is too low, it could indicate a problem with the pump or motor internals.
   
3. Evaluate Track Performance
   If the tracks are not moving as expected, check for any misalignment or excessive wear. Adjust the track tension or replace worn components.
   
4. Examine Electrical Systems
   If the motor is electrically driven or controlled, check the electrical connections and wiring for faults. A malfunctioning electrical system can impact motor performance.
   

The Komatsu D31P-20 and Its Unified Lubrication Strategy
The Komatsu D31P-20 is a mid-sized crawler dozer designed for low ground pressure applications, often used in forestry, grading, and wetland construction. Introduced in the late 1980s, the D31P series was part of Komatsu’s push to simplify maintenance and reduce operator error by specifying a single oil type—engine oil—for use throughout the machine, including the engine, transmission, hydraulics, and final drives.
Komatsu, founded in 1921, has long emphasized reliability and operator-friendly design. By the time the D31P-20 was released, Komatsu had already established a strong global footprint, with tens of thousands of units sold across North America, Asia, and Australia. The unified oil specification was a deliberate engineering choice, aimed at reducing the risk of cross-contamination and simplifying field service.
Why Heavier Gear Oil Seems Appealing but Can Be Risky
Operators often wonder whether switching to heavier gear oil—such as SAE 80W-90 or 80W-140—in the final drives could improve protection under extreme pressure. On the surface, this seems logical: final drives endure high torque loads, and thicker oil might cushion the gear teeth better.
However, gear oils typically contain EP (Extreme Pressure) additives, including sulfur compounds. These additives are designed to prevent metal-to-metal contact under high load, but they can react chemically with copper and bronze components found in bushings and thrust washers. If the final drive wasn’t engineered for gear oil, this reaction can lead to accelerated wear, pitting, and eventual failure.
Terminology Clarification

• Final Drive: The last stage in the drivetrain that transmits power from the transmission to the tracks or wheels.
  
• EP Additives: Chemicals added to gear oil to reduce wear under extreme pressure; often sulfur-based.
  
• Unified Lubrication: A design philosophy where one oil type is used across multiple systems to simplify maintenance.
  

• SAE 50 engine oil has a similar viscosity to SAE 80W-90 gear oil at operating temperature.
  
• SAE 30 engine oil is roughly equivalent to SAE 75W gear oil.
  

• Use the oil grade specified by the manufacturer unless a service bulletin recommends otherwise.
  
• Change final drive oil at the same interval as engine oil—typically every 250 hours or annually.
  
• Inspect magnetic drain plugs for fine metal particles, which indicate early wear.
  
• Avoid mixing oil types or brands without verifying additive compatibility.
  

In recent years, North Carolina has introduced significant updates to its weight laws, specifically aimed at regulating the weight limits of heavy equipment and machinery transport. These changes have had a profound impact on the logistics and transportation industries, requiring both operators and businesses to adapt to new rules. This article explores the key aspects of the new weight laws, their implications for transporters, and the necessary steps for compliance.
Overview of North Carolina’s New Weight Laws
North Carolina's new weight laws primarily focus on the legal load limits for vehicles transporting heavy equipment, construction machinery, and other large items. These changes were implemented to reduce road damage, enhance safety, and ensure that equipment transporters adhere to safe operational guidelines.
The main adjustments to the state's weight laws include revisions to allowable axle weights, gross vehicle weight (GVW), and gross axle weight rating (GAWR). These weight limits are now strictly enforced through both static weigh stations and mobile inspection units located along key transport routes.
Key Changes in Weight Limits

1. Increased Scrutiny of Axle Weights
   Under the new laws, individual axle weight limits have been lowered in some cases, while others have been raised depending on the axle configuration. The intent behind this change is to ensure that weight is distributed more evenly across all axles, which helps prevent excessive stress on roads and bridges.
   • Example: For certain vehicles carrying heavy loads like excavators or bulldozers, the limit on single axle weight may be set at 20,000 pounds, with tandem axles allowed up to 34,000 pounds. This ensures that no single point on the road bears too much weight.
     
2. Gross Vehicle Weight (GVW) Adjustments
   The overall GVW for certain vehicles has been adjusted to match the vehicle's design and the weight of the load it is carrying. This change ensures that both loaded and unloaded vehicles are in compliance with the new weight standards.
   • Example: A standard tractor-trailer combination used for transporting heavy equipment may see its GVW limit rise from 80,000 pounds to a more specific, regulated weight depending on the trailer configuration and number of axles.
     
3. Bridge Formula Enforcement
   North Carolina’s weight laws now strictly enforce the bridge formula, a system that determines how much weight a truck can carry based on the distance between axles. The goal of this formula is to minimize road damage caused by heavy trucks by ensuring that weight is distributed across multiple axles in a way that reduces stress on bridges.
   • Bridge Formula Basics: The formula calculates weight allowances by dividing the truck's weight by the number of axles and their spacing. This formula helps ensure that no bridge is subject to excessive stress due to overweight vehicles.
     

1. Increased Compliance Costs
   With the stricter enforcement of weight limits, companies must now invest in updated equipment and technologies to comply with the laws. This includes the purchase of more advanced trailers with proper axle configurations, as well as the potential for additional weight monitoring systems.
   • Example: Many companies have opted to install load weight monitoring devices on their equipment, which provides real-time data on the weight of the load being transported. This can help prevent violations during transport.
     
2. Potential for Fines and Penalties
   Failure to comply with the new weight regulations can result in hefty fines. These fines can be imposed at weigh stations or during routine inspections along major transport routes. This makes it essential for businesses to ensure that their vehicles are properly calibrated and meet the state's weight laws.
   • Example: If a truck carrying heavy machinery is found to exceed the allowable weight limit, the company may face fines based on how much the vehicle is over the limit. In some cases, transporters may also be required to pay for road repairs caused by their overloaded vehicles.
     
3. Route Planning and Permits
   Transporters must also account for specific route restrictions related to weight limits. In some cases, roads with lower load-bearing capacities may be closed to vehicles carrying excessive weight. Transporters may need to obtain special permits for oversized loads or use specific routes designated for heavy equipment transport.
   • Permit System: A permit may be required for certain loads that exceed the standard weight or dimensions. Permits allow transporters to carry oversized or overweight loads within specific constraints, such as times of day and routes.
     
4. Operational Changes for Fleet Management
   Fleet operators must now adjust their load planning strategies to align with the new weight restrictions. This could involve reducing the size of individual loads, using lighter equipment, or splitting the load across multiple trips or vehicles.
   • Load Management: Transporters may be required to reduce the weight of certain loads by disassembling equipment into smaller parts before transport. This not only ensures compliance with weight laws but also improves safety during transport.
     

1. Invest in Weight Monitoring Technology
   Installing weight monitoring systems on transport vehicles can help operators track load weight and ensure that they are within the legal limits. This technology provides real-time data, which is especially helpful for long hauls where weight fluctuations can occur due to fuel consumption or other factors.
   
2. Regular Maintenance and Calibration
   Ensuring that the equipment is regularly maintained and calibrated is essential for compliance. This includes checking axle weight limits and making adjustments to the load distribution as needed.
   
3. Train Drivers on New Regulations
   Drivers should be trained on the importance of adhering to weight limits and the penalties for violations. Regular training can help drivers understand how to manage loads efficiently and avoid errors during transport.
   
4. Work with State Authorities
   Transporters should stay in close contact with state authorities to ensure they are up to date with the latest regulations. Some state agencies offer resources such as online tools for checking weight limits and route restrictions, making it easier for transporters to plan their routes.
   

Understanding the Role of the Fuel Sending Unit
The fuel sending unit is a critical component in any internal combustion engine system, responsible for measuring the fuel level inside the tank and transmitting that data to the gauge on the dashboard. In older mechanical systems, this was done via a float arm and variable resistor. Modern systems often use electronic sensors, but the sealing challenge remains consistent across generations.
When replacing a sending unit—whether due to corrosion, inaccurate readings, or tank refurbishment—ensuring a proper seal is essential. A poor seal can lead to fuel vapor leaks, contamination ingress, and even fire hazards in extreme cases. This is especially true for equipment like the John Deere 310B, a backhoe-loader introduced in the late 1970s and widely used in municipal and construction fleets across North America. With thousands still in operation today, maintenance practices for these machines remain highly relevant.
Common Sealant Options and Their Properties
When sealing a sending unit to the fuel tank, technicians typically choose between several types of sealants. Each has its own chemical properties, temperature tolerance, and compatibility with fuel systems.

• Permatex No. 2: A non-hardening, slow-drying sealant ideal for threaded connections and flanges. It resists gasoline and diesel, making it a popular choice for fuel system components. Its pliability allows for easy disassembly later, which is useful for older machines that may require frequent service.
  
• Anaerobic Gasket Makers: These sealants cure in the absence of air and are often used between machined metal surfaces. While effective, they require clean, oil-free surfaces and may not bond well to aged or pitted tank flanges.
  
• PTFE Thread Sealant: Commonly used on pipe threads, PTFE (Teflon) sealants resist fuel and offer excellent sealing properties. However, they are not ideal for flat flange surfaces and may degrade under high vibration.
  
• Rubber Gaskets with Fuel-Resistant Adhesive: Some technicians prefer to use a rubber gasket paired with a fuel-resistant adhesive or sealant. This method mimics OEM-style sealing and can be highly effective if the gasket material is compatible with fuel.
  

• Flange: A flat surface on the tank where the sending unit mounts. It often includes bolt holes and a sealing groove.
  
• Threaded Connection: A screw-type interface where sealant is applied to prevent leaks.
  
• Fuel-Resistant: A material that does not degrade when exposed to gasoline, diesel, or ethanol blends.
  

• Clean the flange surface thoroughly with a solvent that evaporates quickly, such as brake cleaner.
  
• Inspect the tank for pitting, rust, or warping. Surface irregularities can compromise the seal.
  
• Apply sealant evenly, avoiding excess that could squeeze into the tank and contaminate fuel.
  
• Torque bolts to manufacturer specifications. Over-tightening can distort the flange and break the seal.
  
• Allow sealant to cure fully before refueling or operating the machine.
  

When dealing with a voltage loss to the starter on a 2002 Liftking forklift, operators and mechanics need to systematically diagnose the issue to restore functionality.

2. Damaged or Loose Wiring
   The electrical wiring connecting the battery to the starter motor is critical for proper functionality. Over time, wiring can become brittle, corroded, or disconnected due to wear and tear. Loose or damaged connections can create voltage loss at critical junctions, preventing the starter from receiving the necessary voltage.
   • Inspect the Wiring: Carefully inspect all wiring connected to the battery, relay, and starter. Look for any signs of corrosion, fraying, or loose connections. If any issues are identified, repair or replace the affected wires.
     
3. Defective Starter Motor or Solenoid
   The starter motor itself could be faulty or experiencing internal issues. A worn-out starter solenoid can also prevent the motor from engaging properly. Solenoids are responsible for transmitting the electrical current to the starter motor when the ignition switch is turned on.
   • Test the Starter: If the wiring and battery are in good condition, but the forklift still won't start, the starter motor or solenoid may need to be tested. A mechanic can perform a bench test on the starter motor to check for proper function. If the starter is defective, replacing it may be necessary.
     
4. Blown Fuses or Relays
   Fuses and relays are essential components that protect the forklift's electrical circuits. A blown fuse or faulty relay can cause a loss of power to the starter motor, preventing it from engaging.
   • Check Fuses and Relays: Inspect the relevant fuses and relays in the electrical system, particularly the ones related to the starting circuit. If any fuses are blown, replace them with the appropriate rated fuses. Additionally, check for faulty relays and replace them if needed.
     
5. Ignition Switch Issues
   The ignition switch plays a crucial role in activating the starter motor. A malfunctioning ignition switch could fail to send the signal to the starter, causing voltage loss and preventing the engine from starting.
   • Test the Ignition Switch: If other components appear to be in working order, the ignition switch may need to be tested. A multimeter can be used to check for continuity when the key is turned to the "start" position. If there is no continuity, the switch may need to be replaced.
     

• Regular Battery Inspections: Periodically check the battery's voltage, terminals, and connections to ensure they are in good condition.
  
• Keep Wiring Clean and Secure: Inspect the wiring for any signs of wear, corrosion, or damage. Secure loose connections to prevent voltage drops.
