🔌 Function

Transfers combustion force from the piston to the crankshaft and converts reciprocating piston motion into crankshaft rotation.

⚠️ Common Signs of Failure

• Knocking from the big-end or small-end
• Bent or twisted rod causing piston or liner wear
• Fretting at the cap joint
• Cracks, heat discolouration or damaged bolt seats
• Repeated bearing failure or abnormal piston protrusion

🛠️ Service Notes

• Return each rod to its own bore and its original orientation, with its own cap the right way round — caps are machined with their rod and are not interchangeable
• Fit new connecting rod bolts unless the manual for your engine expressly permits reuse, and follow its torque-plus-angle sequence exactly; these fasteners are stretched into place, and a reused or mis-tightened bolt is a thrown rod
• Measure the journals, the bearing shells and the rod's big-end and small-end bores against the figures in the manual for your engine, and check the rod for bend and twist before it is used
• Fit the shells clean and dry into their seats with the locating tabs home, then oil only the running faces — never scrape, shim or adjust a bearing shell
• Lubricate the bolt threads and faces only as the procedure specifies, and check the rod turns freely with the correct side clearance before moving on
