Installation & Application Notes

Flush cooling system with distilled water before refilling. Use pre-mixed coolant — never plain water, which causes corrosion. Pressure-test system after any cooling repair. Check thermostat by immersing in hot water — should open at rated temperature.

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

Failure Symptoms

Early signs of a failing gear assembly include grinding noises during operation or noticeable play in the drive train. If ignored, the issue can progress to intermittent power loss or complete inability to drive the machine. Continued operation risks significant damage to the transmission and drive components.

Installation Tip

Ensure proper lubrication of all gear teeth and bearings before assembly to prevent initial wear. Avoid forcing components together; they should mesh smoothly.

Service Note

Inspect the transmission fluid for metal particles and check the condition of the drive shafts and universal joints.
