Piston Ring, Engine


On these engines, replacement rings are available in standard size only. If piston ring clearance is excessive, the piston and cylinder liner must be replaced. Refer to ``Cylinder Liner, Replace'' procedure.


Piston pins are a matched fit with the piston and are not available for separate replacement. Piston pins are pressed into the connecting rods and will not become loose enough to cause a knock or tapping until after very high mileage.
