P&H 18 crane background and hydraulic configuration
The P&H 18 is a mid-sized hydraulic crane produced by P&H Harnischfeger, a company with deep roots in American lifting equipment dating back to the early 20th century. These cranes typically use fixed-displacement gear or vane pumps to power swing, steering, and outrigger functions. The hydraulic system includes:

• A fixed-displacement pump driven by the engine
  
• Directional control valves for swing and outrigger extension
  
• Pressure relief valves to protect components
  
• Return lines and tank circuits
  

• Missing or misadjusted relief valve: Without a properly set relief valve between the pump and control valves, pressure has nowhere to go when flow is blocked.
  
• Deadheaded pump: If the control valve was closed or a port was plugged, the pump would build pressure until failure.
  
• Incorrect hose routing: A return line connected to a pressure port or a blocked outlet can trap flow.
  
• Overcompensation from prior leaks: If the old pump was leaking, someone may have increased relief pressure to compensate, leaving the new pump vulnerable.
  

• Install a relief valve rated for the pump’s maximum pressure, typically 2,500–3,000 PSI
  
• Verify valve orientation and flow direction
  
• Check for plugged ports or incorrect fittings
  
• Inspect control valve spools for sticking or misalignment
  

• Always verify relief valve presence and setting before startup

The undercarriage of a Komatsu PC60-6, or any crawler excavator for that matter, is a critical component that ensures stability, mobility, and performance in tough working conditions. Over time, the undercarriage components—such as the track, rollers, sprockets, and idlers—wear down due to constant stress from the machinery's movements on rugged terrain. When these parts degrade, they can lead to costly repairs and even equipment failure if not properly addressed. This article walks through the steps and considerations necessary for a successful undercarriage rebuild on a Komatsu PC60-6.
Understanding the Importance of the Undercarriage
The undercarriage on a Komatsu PC60-6 is made up of several key components: tracks, track rollers, idlers, sprockets, and the final drive. Together, these parts work to support the weight of the machine, enable smooth movement, and ensure traction on a variety of surfaces. The undercarriage is constantly exposed to harsh working environments, which accelerates wear and tear.
As one of the most expensive components of an excavator, the undercarriage requires proper maintenance to extend its life. While individual parts can be replaced, a full rebuild may be necessary when the wear is too extensive or when frequent repairs are no longer cost-effective.
Signs of Undercarriage Wear
Before diving into a rebuild, it’s essential to understand when the undercarriage is too worn and requires a complete overhaul. Common signs of wear include:

1. Uneven Track Wear: If the tracks appear unevenly worn, it could indicate that certain components like the track rollers or idlers are damaged or misaligned.
   
2. Excessive Noise or Vibration: Unusual sounds or vibrations during operation often point to worn rollers, sprockets, or other undercarriage components.
   
3. Loose or Worn-Out Tracks: If the tracks feel loose or have too much slack, it may mean that the track tensioners or rollers are failing.
   
4. Frequent Downtime: Constant breakdowns and repairs related to undercarriage components are clear signs that a rebuild is due.
   

1. Tracks
   The tracks are the most visible and essential part of the undercarriage. Over time, the track links wear down and can become stretched or damaged. If the tracks are worn beyond repair, they must be replaced entirely. Proper tensioning of the tracks is crucial for preventing excessive wear on the other components.
   
2. Track Rollers
   Track rollers are responsible for supporting the weight of the machine and guiding the tracks. They are subject to constant wear, especially when the excavator operates in rough or abrasive conditions. Worn-out rollers can lead to the tracks slipping or uneven wear, necessitating their replacement.
   
3. Sprockets
   The sprockets engage with the track links to provide motion. Over time, the teeth of the sprockets can wear down, leading to poor track engagement and reduced traction. Replacing the sprockets when they show significant wear is essential for maintaining smooth and efficient operation.
   
4. Idlers
   Idlers are located at the front of the track system and help guide the track as it moves. Worn or damaged idlers can cause misalignment, making the tracks track unevenly. Replacing idlers ensures proper track alignment and smooth operation.
   
5. Track Shoes
   The track shoes are the parts that actually make contact with the ground, providing traction. When the shoes are worn down, they need to be replaced to maintain the machine’s grip and mobility on various surfaces.
   
6. Final Drive
   The final drive is the last stage of the powertrain, transferring the engine’s power to the tracks. If the final drive is damaged or shows signs of leaking, it must be addressed immediately, as this can lead to a complete loss of traction.
   

1. Assessing the Condition
   Before starting the rebuild, inspect the entire undercarriage to assess which components need replacement. This involves checking for signs of wear, cracks, and damage to the tracks, rollers, sprockets, and idlers. Regular maintenance or a professional technician can help determine the severity of the wear.
   
2. Disassembly
   Once the condition of the parts has been assessed, the next step is disassembling the undercarriage. This includes removing the tracks, rollers, sprockets, and idlers. Depending on the level of wear, it may also involve removing the track frame or other associated parts.
   
3. Cleaning and Inspection
   After disassembly, thoroughly clean all components to remove dirt, debris, and grease. This helps ensure that any remaining wear or damage can be identified. It's also an opportunity to inspect the final drive and other critical parts for any issues that need attention.
   
4. Replacing Worn Components
   Replace all worn-out or damaged components, including the tracks, rollers, sprockets, and idlers. Depending on the level of wear, the track frame might also need to be replaced or repaired.
   
5. Reassembly and Calibration
   Once all new parts are installed, the undercarriage is reassembled. This includes properly tensioning the tracks and adjusting all components for optimal operation. Calibration is essential to ensure that everything is aligned correctly and that the system operates efficiently.
   
6. Testing and Fine-Tuning
   After reassembly, test the machine to ensure smooth operation. This may include checking the track alignment, the operation of the rollers, and the overall stability of the undercarriage. If there are any signs of malfunction or misalignment, further adjustments may be needed.
   

• Labor Costs: Rebuilding the undercarriage is labor-intensive, and depending on your location and the service provider, labor costs can add up quickly.
  
• Parts Costs: High-quality replacement parts, including tracks, rollers, sprockets, and idlers, are crucial for ensuring long-lasting performance. It’s essential to choose parts that match the specifications of the Komatsu PC60-6 for proper functionality.
  
• Downtime: While the rebuild is being performed, your equipment will be out of operation. Depending on the scale of the rebuild, this can range from several days to a few weeks, depending on your maintenance schedule.
  

1. Regular Inspection: Conduct regular visual inspections of the tracks, rollers, and other components to catch signs of wear early. Identifying issues before they become major problems can save money in the long run.
   
2. Proper Track Tensioning: Ensure the tracks are properly tensioned to avoid unnecessary strain on the rollers and sprockets.
   
3. Lubrication: Keeping the undercarriage components properly lubricated will minimize friction and reduce wear.
   
4. Avoid Overloading: Overloading the machine puts extra strain on the undercarriage, accelerating wear and tear. Always operate within the manufacturer’s recommended load limits.

Water separators are essential components in the fuel systems of modern heavy machinery. Particularly in tracked skid steers like those made by ASV (Aultman-Smith Vibratory), water separators play a critical role in protecting the engine and fuel system from water contamination. These systems prevent costly repairs and ensure the machinery operates efficiently, even in harsh environmental conditions.
What is a Water Separator and Why is it Important?
A water separator is designed to remove any water present in the fuel before it reaches the engine. Water contamination in fuel can come from various sources, such as condensation, storage issues, or fuel delivery. If not properly filtered out, water can cause significant damage to the engine by corroding components, leading to performance problems, misfires, and even engine failure.
In heavy equipment like ASV machines, which are often used in rough and demanding environments, the need for effective water separation is even more critical. A clogged or faulty water separator can lead to fuel system blockages, poor engine performance, and costly repairs.
How Does an ASV Water Separator Work?
The ASV water separator operates by using a combination of mechanical and filtration processes to remove water from the fuel. When fuel enters the separator, it is forced through a filter medium that captures water droplets. These water droplets are then collected at the bottom of the separator and drained out through a valve.
Typically, the separator also includes a sensor that detects the accumulation of water. Once the water reaches a certain level, the sensor triggers a warning light or an alarm to alert the operator that the separator needs to be drained. This feature is crucial in preventing water from bypassing the filter and reaching the engine.
Common Issues with ASV Water Separators

1. Clogging and Poor Performance
   Over time, the filter element within the water separator can become clogged with dirt, debris, and accumulated water. A clogged filter can restrict fuel flow, reduce engine efficiency, and increase the risk of water contamination. Regular maintenance and timely replacement of the filter are essential to keep the separator functioning properly.
   
2. Faulty Sensors and Warning Lights
   The water level sensor in the separator is vital for ensuring the system is operating efficiently. If the sensor malfunctions or fails, the operator may not receive the necessary warning to drain the separator, allowing water to bypass the filter. This can result in engine performance issues or damage over time.
   
3. Water Drainage Problems
   If the valve designed to drain accumulated water becomes stuck or clogged, the separator will fail to discharge the water properly. This can lead to water accumulating in the fuel system, which might damage sensitive engine components. A regular inspection of the drainage valve is necessary to ensure it operates smoothly.
   
4. Improper Installation or Incorrect Maintenance
   Sometimes, issues with the water separator arise due to improper installation or neglect during maintenance. If the system is not installed correctly, or if the filter is not replaced regularly, it can compromise the entire fuel system’s performance. Following the manufacturer’s recommended maintenance schedule is critical for avoiding such issues.
   

1. Regularly Check and Replace Filters
   Fuel filters, including water separator filters, should be inspected at regular intervals. In most cases, manufacturers like ASV recommend changing the filter after a set number of hours of operation, or if the water separator is not functioning as expected. If the filter shows signs of clogging or wear, it’s time for a replacement.
   
2. Drain the Water Separator Frequently
   Depending on the working environment, the water separator may need to be drained more often. In areas with high humidity or heavy rainfall, water accumulation in the fuel tank can occur more quickly. Operators should monitor the water level closely and drain the separator whenever necessary.
   
3. Check the Sensors and Warning Systems
   It’s important to test the water level sensor and ensure the warning system is functioning. If the sensor fails to activate, you may not receive any alert that the water separator needs to be drained. Regularly testing the system by simulating high water levels will ensure the sensor is working properly.
   
4. Inspect the Drainage Valve
   The drainage valve should be checked regularly for obstructions or signs of damage. A blocked or faulty valve will prevent the water from being properly discharged, which could lead to fuel system contamination. Ensuring the valve operates freely is key to preventing water damage.
   

Quick answer
Prefilling fuel filters is often necessary to avoid long cranking times and air lock issues, especially on older diesel systems. Prefilling oil filters is more controversial—some mechanics avoid it due to contamination risk, while others argue it reduces dry-start wear. The decision depends on engine design, filter orientation, and available priming systems.
Fuel filter prefilling and system behavior
Diesel engines rely on uninterrupted fuel delivery. When filters are replaced dry, air enters the system, causing hard starts or complete failure to prime. This is especially problematic in engines with:

• Stanadyne rotary pumps
  
• Detroit Diesel gear pumps
  
• Mechanical injection systems without electric priming
  

• Prefill fuel filters when no electric priming is available
  
• Use clean, filtered fuel from a dedicated container
  
• Avoid pouring old fuel into new filters unless absolutely necessary
  

• Introducing contaminants into the clean side of the filter
  
• Spilling oil into the center port, bypassing filtration
  
• Overfilling or misjudging filter orientation
  

• Fuel filters:
  • Prefill when possible, especially on older systems
    
  • Use clean fuel and avoid contamination
    
  • Bleed air using hand or electric pumps
    
• Oil filters:
  • Prefill only if filter mounts upright
    
  • Pour into outer ring, not center hole
    
  • Use fresh oil and clean containers
    
• Hydraulic filters:
  

• Prefill if system lacks precharge or accumulator
  
• Monitor fluid level after startup

When choosing heavy equipment, understanding how different brands' machines compare in terms of specifications, performance, and overall utility is crucial. For example, if you own or operate Shantui machinery, you may want to identify equivalent models from Caterpillar (CAT) or other leading manufacturers. This can help in parts sourcing, service, and fleet management, especially in markets where parts and service availability for Shantui might be limited. The challenge lies in understanding how to find the best equivalent models across various brands. This article explores how to match Shantui equipment to its counterparts from other manufacturers and offers tips on what to look for during this process.
Understanding Shantui's Position in the Market
Shantui is a prominent Chinese manufacturer of construction machinery, especially known for its bulldozers and other heavy equipment. The company has grown over the years, becoming one of the largest producers of construction equipment in China, and has expanded its presence internationally. Shantui offers a range of products, including bulldozers, excavators, graders, and loaders.
Despite the quality of their products, Shantui machines often face challenges in terms of parts availability, global service networks, and dealer support, particularly outside China. This is why many operators and businesses look for equivalent models from established global brands like Caterpillar, Komatsu, and Volvo.
How to Find Equivalents of Shantui Machines
When seeking equivalent models for Shantui machines, there are several key factors and specifications to consider. While it is tempting to compare equipment solely by weight or horsepower, these factors alone don’t always give a full picture of the performance, operational costs, and long-term reliability. Below are some of the key steps to follow when trying to match a Shantui machine with a comparable model from other manufacturers.
Step 1: Match Power Ratings and Engine Specifications
The first step in finding an equivalent machine is to compare the engine power and size. Shantui bulldozers, for example, come with different horsepower ratings depending on the model. For instance, the Shantui SD16 is powered by a 162-horsepower engine, while the SD22 offers a 220-horsepower engine.
When looking for an equivalent from another manufacturer, you should compare the engine power and displacement. For example, a Caterpillar D6T bulldozer has a similar horsepower rating to the Shantui SD16 and can be considered an equivalent. Similarly, the CAT D7R might match the SD22 due to its higher horsepower and similar application range.
Step 2: Compare Operational Weight and Size
The operational weight of the equipment is an essential specification to compare because it directly impacts the machine's stability, lifting capacity, and the type of work it can handle. The weight also affects transportation and maneuverability on different job sites.
For example, the Shantui SD16 bulldozer weighs approximately 16 tons, while the CAT D6T weighs about 18 tons. Both are suitable for medium-duty tasks such as road building, earthworks, and land clearing, making them comparable. On the other hand, larger machines like the Shantui SD22, with its 22-ton weight, would align better with a Caterpillar D7 or Komatsu D65.
Step 3: Focus on Hydraulics and Performance Features
Hydraulic performance is another area to consider when comparing equipment. Look at parameters like hydraulic flow rates, lifting capacities, and the type of hydraulic systems used. A Shantui dozer with high hydraulic power may be matched by similar high-flow systems in machines like the CAT D6 or Komatsu D61.
It's also crucial to evaluate the dozer’s blade size and angle, as well as its lift height and reach. These features will help determine whether the machine can handle specific attachments, such as ripper arms, or perform certain tasks like grading and leveling.
Step 4: Consider Fuel Efficiency and Operating Costs
Fuel efficiency and maintenance costs play a significant role in the long-term value of the equipment. Shantui, like many other Chinese brands, focuses on producing fuel-efficient models designed to reduce operational costs. However, global manufacturers like Caterpillar and Komatsu often lead the market in offering advanced fuel-saving technologies, such as advanced engine management systems.
When comparing machines, consider the expected fuel consumption per hour of operation. For example, the Shantui SD16’s fuel consumption is around 10-15 liters per hour, depending on the load and task. In comparison, the CAT D6T might consume slightly more fuel but offers enhanced fuel efficiency due to its higher engine power and advanced fuel systems.
Step 5: Review Service Networks and Parts Availability
One of the primary considerations when comparing equipment is the service network and parts availability. Global brands like Caterpillar have extensive service networks and offer readily available parts in most parts of the world. Shantui, on the other hand, may not have as widespread service coverage, especially in regions outside China.
This means that while the initial cost of a Shantui machine might be lower, the long-term service and parts availability could become a concern. Operators might prefer Caterpillar or Komatsu models in areas with limited access to Shantui dealers. This factor should be weighed heavily, particularly if you rely on consistent machine uptime and service support.
Step 6: Seek Expert Advice and Use Machine Databases
Using machine databases or consulting with experts in the field can significantly aid in the equivalency search. Many websites, like EquipmentWatch and MachineryTrader, offer detailed specifications and comparisons between different models, which can help make a more informed decision.
Additionally, dealers who handle multiple brands might be able to provide insights into which models have similar specifications and applications. Leveraging such advice ensures that you select the machine that best fits your needs.
