🔌 Function

Converts the pistons' reciprocating motion into rotation, carrying the firing loads through its main and big-end journals to the flywheel.

⚠️ Common Signs of Failure

• Deep knock from the bottom end, worst under load
• Oil pressure falling away as the engine warms
• Bearing shells worn through to copper or with embedded debris
• Journals scored, oval, or blued from overheating
• Metal particles in the oil and on the filter element

🛠️ Service Notes

• The serial breakpoint matters on crankshafts, so confirm the engine serial falls within the published series before ordering
• Renew all main and big-end bearings, the thrust washers and both crankshaft seals with the crankshaft, and check the block bores and rod alignment
• Plan the lift and the handling, as a 90 kg crankshaft is easily damaged if it is allowed to knock against anything
