⚠️ Common Signs of Failure

• Pitting, spalling or broken gear teeth
• Abnormal whine, knock or backlash
• Metal debris in the lubricating oil
• Wear at the bore, keyway or mounting face
• Drive interruption or loss of timing/accessory operation

🛠️ 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
