- Measure the piston protrusion compared to the head plane
and use the chart below, to determine the proper base gas-
ket thickness. The proper base gasket thickness guarantees
the engine will run at the correct compression ratio.
- Remove the specific tool and the cylinder.

- Carefully clean the piston ring grooves using an old piston
ring.
- Using a reed thickness gauge, measure the play between
the piston rings and the grooves as shown in the figure.
- If any play is found to be greater than specified in the table
below, replace the piston and the piston rings.
