Front Gear Housing and Gear Train
Troubleshooting the front gear housing and gear train
consists of checking for leaks at the gaskets (front
cover, and injection pump) and the front crankshaft oil
seal, inspecting the gears and measuring backlash
when required.
Gear noise emitted from the cover can indicate worn
gear teeth.
Note : Excessive backlash can affect engine timing
and engine performance.
