🔌 Function

Converts the pistons' reciprocating motion into rotation and carries the main and big-end bearing journals that support the whole bottom end.

⚠️ Common Signs of Failure

• Deep knocking from the bottom end, worst under load
• Oil pressure falling away, especially when hot
• Bearing material found in the sump or filter
• Journals measured oval, tapered or scored on strip-down
• Crankshaft found bent or the thrust face worn, giving end float out of specification

🛠️ Service Notes

• At 88 kg this is a freight item that needs two people or lifting gear, and it should be supported at the journals in transit and on the bench
• Confirm the engine serial falls in the 20711/78962 to 97292 range before ordering, as the crankshaft changed within the series
• Renew all main and big-end bearings, the thrust washers and the front and rear seals with it, and have the block bores checked for alignment
