7N9343 Thrust Plate — Cat 120G 12G

This thrust plate is a precision-engineered component designed to manage axial forces within an engine's rotating assembly, typically in the crankshaft system. Manufactured to meet rigorous quality standards, it provides essential wear resistance and maintains proper bearing clearances, unlike worn plates that can cause excessive end play. Operators may notice increased engine noise, particularly a knocking sound, or a drop in oil pressure when this component is failing.

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

Early signs of thrust plate wear might include a faint knocking sound that increases with engine RPM. If ignored, this can progress to a more pronounced engine knock and a noticeable increase in crankshaft end play, potentially leading to bearing damage. Continued operation risks severe internal engine damage.

Installation Tip

Ensure that the crankshaft and connecting surfaces are perfectly clean and free from any burrs or imperfections before installing the thrust plates. Always install thrust plates in their correct orientation as specified by the service manual.

Service Note

Inspect crankshaft thrust bearings and the crankshaft itself for wear or scoring when replacing thrust plates.
