Fitting Piston Pins: Removal
- Remove bearings from connecting rods and cap. Mark pistons, pins and inserts (if reusable) to assure assembly with same rod. Press pin from piston and rod using arbor press and Piston Pin Remover/Installer (J-24086). See Fig 1.
- Replace piston pins showing fractures, etching or wear. Check pin-to-rod bore fit. Check ID of rod pin bore and replace if bore is to large. Ensure proper fit by honing or reaming piston pin bore to light slip fit. Standard piston pin diameter is .9803-.9807" (24.899-24.909 mm). Lubricate pin and small end of rod bore with oil.
