## 🔌 Function

The gear meshes with adjacent gears in the engine's drive train to transfer rotational motion and torque at a fixed ratio. Correct tooth condition and mesh clearance are essential to maintaining accurate drive timing and quiet, reliable operation.

## ⚠️ Common Signs of Failure

-   Whining, howling or rattling noise from the gear train that changes with engine speed
-   Chipped, pitted or visibly worn gear teeth on inspection
-   Excessive backlash or play when the gear is rocked against its mate
-   Metal particles or fine debris found in the engine oil or on the drain plug
-   Timing drift or rough running caused by worn tooth flanks

## 🛠️ Service Notes

-   Inspect the mating gear as well as the one being renewed; a chipped or worn tooth on the partner will quickly ruin a new gear, so change them as a pair where the wear is shared
-   Check the shaft, bush or bearing the gear runs on for wear and scoring before assembly and renew anything that is not to size
-   Fit the gear square and press it home rather than driving it with hammer blows, which spread the bore and mark the teeth
-   Oil the teeth and bearing surfaces on assembly so the gear is not run up dry on first start
-   Where the workshop manual for your engine gives backlash, end float or timing settings for the gear, set and check them to those figures rather than by feel
