🔌 Function

Transfers crankshaft rotation into the engine timing-gear train and establishes the mechanical timing reference for the camshaft and driven accessories. Accurate tooth condition and gear alignment are essential for stable valve timing and long gear-train life.

⚠️ Common Signs of Failure

• Timing-case knock, gear whine or irregular mechanical noise
• Chipped, pitted, cracked or abnormally polished gear teeth
• Excessive timing-gear backlash or metal contamination in the timing case
• Camshaft timing or synchronisation faults
• Severe engine damage if tooth failure allows the timing relationship to change

🛠️ 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
