⚠️ Common Signs of Failure

• Knocking that rises with load and is worst on the overrun
• Big-end shell worn, scored or picked up
• Rod bent or twisted, showing as uneven piston wear
• Bolt threads stretched, or the cap fretted
• Metal in the oil, or a bearing knock on start-up

🛠️ Service Notes

• Two earlier numbers, 21194630 and 21188652, were both listed as piston rods and now come to this one, so an old parts list may point at either
• Connecting rod bolts are usually single-use and angle-tightened — check the current instructions rather than reusing them
• Have the rod checked for bend and twist and the big-end bore measured before reusing anything
