Installation & Application Notes

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a failing travel motor assembly is often a reduction in the speed or power of one or both tracks, leading to uneven or sluggish movement. If the issue progresses, you may experience complete loss of drive to one side, or the machine may refuse to move altogether. Ignoring these symptoms can lead to further damage to the drive gears, final drive housing, or hydraulic system.

Installation Tip

Ensure the hydraulic fluid is clean and at the correct level before installation, and prime the new motor with fluid to prevent dry start-up. Do not reuse old mounting hardware; use new bolts and washers to ensure a secure and leak-free connection.

Service Note

Inspect the final drive oil level and condition, check the drive shaft and sprocket for wear, and examine the hydraulic lines for leaks.
