⚠️ Common Signs of Failure

• Cracks, heat checking or damaged starter-ring teeth
• Loose flywheel fasteners or fretting at the crankshaft flange
• Clutch/driven-equipment engagement problems
• Abnormal starter noise or failure to engage

🛠️ Service Notes

• Housing standard and disc size decide the fit - this is the SAE 1 housing, 14 inch disc listing
• Inspect the ring-gear teeth and the crankshaft flange and dowels before refitting, since starter engagement damage repeats otherwise
• At 70 kg this needs mechanical lifting support during removal and fitting
