FAQ

Q: Can slightly worn thin thrust plate stay in service?
A: Not recommended. Excessive clearance leads to mis-meshing, planetary gear and bearing damage quickly under heavy load.

Q: What happens if oil groove is installed backwards?
A: Lubricating oil cannot reach friction surface, dry friction causes overheating and rapid plate melting and cracking.

Q: Can steel washer replace thrust plate for emergency repair?
A: No. PEEK has self-lubricating property. Steel washer scratches gear surface and fails fast.

Q: Only one plate damaged in one planetary set, can I replace only this one?
A: Not recommended. Other plates share same wear loss. Replace full set to maintain consistent clearance.
