6. Turn the snap rings in the ring grooves until the end gaps are positioned at the bottom of the piston.

PISTON RING REPLACEMENT

1. Remove the piston from the engine block (see CRANKSHAFT AND PISTON REMOVAL ).

2. Using a ring expander (A), remove the old piston rings (B).

3. Clean all ring grooves thoroughly with a squared-off broken ring or ring groove cleaner with a blade to fit

the piston grooves. The top and 2nd ring grooves are 1.2 mm (0.05 in.) wide. The oil ring groove is 2.0
mm (0.08 in.) wide. File down a blade if necessary. Do not use a wire brush to clean the ring grooves, or
cut the ring grooves deeper with the cleaning tools.

4. Using a piston that has its rings removed, push a new ring (A) into the cylinder bore 15-20 mm (0.6 -0.8

in.) from the bottom.

NOTE:

If the piston is to be separated from the connecting rod, do not install new
rings yet.

5. Measure the piston ring end-gap (B) with a feeler gauge:



If the gap is too small, check to see if you have the proper rings for your engine.



If the gap is too large, recheck the cylinder bore diameter against the wear limits (see BLOCK
AND PISTON INSPECTION ). If the bore is beyond the service limit, the engine block must be
rebored.
