🔌 Function

The gear meshes with adjacent gears in the engine's geartrain to transmit rotational drive and maintain correct timing between driven components. Correct tooth engagement and backlash are essential for quiet, reliable power transfer.

⚠️ Common Signs of Failure

• Whining, howling or rattling noise from the geartrain that changes with engine speed
• Visible chipped, pitted or worn gear teeth on inspection
• Excessive backlash or play when the gear is rocked against its mating gear
• Metal particles or debris found in the oil or on the sump magnet
• Timing drift or difficulty setting timing due to worn tooth profiles

🛠️ 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
