2. Measure the connecting rod large end side clearance. If it exceeds the specification, replace the piston, piston pin, piston ring and connecting rod as a single unit.
Connecting rod side clearance (Standard) 0.14-0.36 mm (0.0056-0141 In)
Connecting rod side clearance (Maximum) 0.435 mm (0.0172 In)
3. Remove the connecting rod cap.
4. Position plastigage atop the journals in the axial direction.
