⚠️ Common Signs of Failure

• Metal glitter in the oil or on the filter element
• Journals scored, ovalled or heat-discoloured on strip-down
• Vibration or crankshaft endfloat outside limits

🛠️ Service Notes

• At 95.25 kg this needs mechanical lifting and freight handling, not normal parcel carriage
• It supersedes 3137903, so both numbers point at this crankshaft
• Renew bearing shells, thrust washers and the crankshaft seals with it, and have the block and rods checked before the new shaft goes in
