Introduction: The Vital Role of Final Drives in Track Skid Steers
Final drives are crucial components in track skid steers, as they transmit power from the engine to the wheels or tracks, allowing the equipment to move. These drives are particularly important in compact track loaders (CTLs), where they endure intense strain during operation in rough terrain. Due to the nature of their work, final drives often face issues such as wear, leakage, and mechanical failure.
In this article, we will explore the role of final drives in track skid steers, common problems operators encounter, and the steps to properly maintain and repair these critical components. We’ll also highlight a few tips on troubleshooting and how to prolong the lifespan of your final drives.
What Are Final Drives and How Do They Work?
A final drive in a track skid steer is a gear reduction unit that receives power from the engine and reduces the speed of the motor while increasing the torque that is sent to the tracks. The assembly consists of several key parts, including the hydraulic motor, planetary gears, and the output shaft, which drives the wheels or tracks. The reduced speed and increased torque allow the machine to exert more force at lower speeds, essential for heavy-duty tasks like digging, lifting, and towing.
The final drive is mounted on each track and operates independently. If one side of the final drive fails, the machine may lose the ability to track properly, which can affect the overall performance and safety of the equipment.
Common Problems with Track Skid Steer Final Drives
Maintaining the final drives in good condition is essential for ensuring the longevity and performance of the skid steer. Here are some tips to extend the life of your final drives:
When a final drive issue arises, repairing the problem is often more cost-effective than replacing the entire assembly. Here’s a general overview of the repair process:
In some cases, the damage to the final drive may be too extensive for a repair to be practical. If the housing is cracked or severely damaged, or if the cost of replacing individual components exceeds the cost of a new final drive, replacement may be the best option. However, this is often a last resort after troubleshooting and partial repairs have been exhausted.
Conclusion: Ensuring Longevity of Your Track Skid Steer Final Drives
The final drives in track skid steers are integral to the machine’s operation, and maintaining them is essential for maximizing the machine's lifespan and performance. By staying proactive with preventive maintenance, regularly checking fluid levels and seals, and addressing issues as soon as they arise, operators can avoid costly repairs and downtime.
When troubleshooting or repairing a final drive, always follow the manufacturer’s guidelines and consider professional help if the issue is beyond your expertise. With proper care, your track skid steer can continue to perform efficiently, even in the most demanding environments.

Common Problems with Track Skid Steer Final Drives
- Leaking Seals
One of the most frequent issues with final drives is leaking seals. Hydraulic fluid or gear oil can leak out due to wear and tear on the seals or damage from debris. If left untreated, the fluid loss can lead to insufficient lubrication, causing further damage to the internal components of the final drive.
Example: A construction crew working on a large commercial project noticed a decrease in the skid steer’s performance after noticing fluid leaking from the final drive. Upon inspection, they found that the seals had worn out due to prolonged exposure to harsh working conditions. Replacing the seals fixed the problem, and the machine returned to optimal performance.
- Worn-Out Gears
Over time, the gears inside the final drive can become worn, particularly in machines that operate in harsh or demanding environments. Worn-out gears can cause reduced power output, jerky movement, or even complete failure of the final drive.
Example: An operator on a forestry project noticed that their skid steer was struggling to maneuver through uneven ground, even when not carrying heavy loads. Upon investigation, they discovered that the gears in the final drive had worn down, causing the machine to lose power. Replacing the gears restored the skid steer's efficiency.
- Hydraulic Motor Failures
The hydraulic motor inside the final drive converts hydraulic pressure into mechanical energy to drive the tracks. If the motor fails, the machine will lose the ability to propel itself. This can happen due to contamination in the hydraulic fluid, improper maintenance, or internal component failure.
Example: A contractor on a construction site was using a track skid steer to move materials when the machine suddenly stopped moving. The hydraulic motor had failed due to contaminated fluid, which caused the motor to seize. After flushing the hydraulic system and replacing the motor, the skid steer was back in action.
- Contaminated Hydraulic Fluid
Contaminated hydraulic fluid can severely damage the final drive. Dirt, debris, and moisture entering the system can degrade the fluid, causing internal components to wear out or seize. Regular fluid checks and maintenance are essential to prevent this issue.
Example: On a mining site, a skid steer’s final drive failed unexpectedly. After troubleshooting, it was determined that contaminated hydraulic fluid had entered the system due to a faulty filter. The solution involved draining the contaminated fluid, cleaning the system, and installing a new filter, which resolved the issue.
Maintaining the final drives in good condition is essential for ensuring the longevity and performance of the skid steer. Here are some tips to extend the life of your final drives:
- Regular Fluid Checks and Changes
One of the most important aspects of maintaining final drives is ensuring the hydraulic fluid or gear oil is at the correct level and free from contaminants. Check fluid levels regularly and replace the fluid as recommended by the manufacturer.
- Inspect Seals and Bearings
Periodically inspect the seals and bearings for signs of wear or damage. If any seals are leaking or bearings are worn, replace them immediately to avoid further damage to the final drive.
- Clean Hydraulic System Filters
The hydraulic system filters should be cleaned or replaced regularly to prevent contaminants from entering the final drive. Contaminated fluid can cause severe damage to the gears and motor inside the final drive, leading to costly repairs.
- Operate Within Manufacturer Guidelines
Operating the machine within the manufacturer's recommended guidelines for load and duty cycle can significantly reduce wear and tear on the final drives. Overloading the machine or using it in extreme conditions for extended periods can lead to premature failure.
- Monitor for Abnormal Noises or Vibrations
Any unusual noises or vibrations while the machine is operating should be investigated immediately. Grinding, whining, or knocking sounds can indicate issues with the final drive gears or the hydraulic motor.
When a final drive issue arises, repairing the problem is often more cost-effective than replacing the entire assembly. Here’s a general overview of the repair process:
- Diagnosis
The first step in any repair is diagnosing the problem. Inspect the final drive for visible leaks, damaged seals, and worn gears. Use diagnostic tools to check the hydraulic pressure and ensure that the hydraulic motor is functioning properly.
- Disassembly
Once the problem is identified, disassemble the final drive assembly to access the internal components. This may require removing the track, disconnecting hydraulic lines, and detaching the final drive from the track frame.
- Replacement of Parts
Replace any worn or damaged components, such as seals, gears, or bearings. Ensure that all replacement parts meet OEM specifications for proper fit and performance.
- Reassembly and Testing
After the repairs are completed, reassemble the final drive, reconnect hydraulic lines, and refill with fresh fluid. Test the final drive under load to ensure it is functioning properly and the problem has been resolved.
In some cases, the damage to the final drive may be too extensive for a repair to be practical. If the housing is cracked or severely damaged, or if the cost of replacing individual components exceeds the cost of a new final drive, replacement may be the best option. However, this is often a last resort after troubleshooting and partial repairs have been exhausted.
