Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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 planet gear may be an unusual grinding or whining sound emanating from the transmission. As wear progresses, gear engagement may become hesitant or rough, accompanied by a loss of driving power. Continued operation with a damaged planet gear risks complete transmission failure and costly repairs.

Installation Tip

Thoroughly clean the transmission housing and all mating surfaces before installing the new gear to prevent contamination. Ensure proper lubrication of the gear teeth and surrounding components during assembly to prevent initial wear.

Service Note

When replacing a planet gear, inspect the entire planetary gear set, including the sun gear, ring gear, and bearings, for signs of wear or damage.
