Connecting Rod Measurement
WARNING: This page is about a different variant/trim than selected.
- Clean the connecting rods in solvent and dry with compressed air.
- Inspect the connecting rods for the following:
- Signs of being twisted, bent, nicked, or cracked
- Scratches or abrasion on the rod bearing seating surface
- If the connecting rod bores contain minor scratches or abrasions, clean the bores in a circular direction with a light emery paper. DO NOT scrape the rod or rod cap.
- Measure the piston pin to connecting rod bore using the following procedure:
- Using an outside micrometer, take 2 measurements of the piston pin in the area of the connecting rod contact.
- Using an inside micrometer, measure the connecting rod piston pin bore.
- Subtract the piston pin diameter from the piston pin bore diameter.
- The clearance should not be more than 0.05 mm (0.0020 in).
- If there is excessive clearance, replace the piston pin.
- If there is still excessive clearance, replace the connecting rod bushing.
