Replacement
1.Using a ring expander, remove the old piston rings.
Clean all the ring grooves thoroughly with a
squared-off broken ring or a ring gtoove cleaner
with a blade to fit the piston grooves.
The top ring groove is 1.2 mm (0.042 in) wide, rhe
second ring groove is 1.2 mm (0.042 in) wide, and
the oil ring groove is 2.8 mm (0.11 in) wide. File
down a blade if necessary.
Do not use a wire brush to clean ring lands, or cutring lands deeper with cleaning tool.
3. Install the new rings in the proper sequence andposition (shown in the right column).
NOTE: lfthe piston is to be separated from the con-
necting rod, do not install new rings yet.

Remove the connecting rod caps, and slip short sections of rubber hose over the threaded ends of theconnecting rod bolts. 4. lnstall the ring compressor, and check that the bear-ang is securely in place. 5. Position the piston in the cylinder, and tap it in usingthe wooden handle of a hammer. Maintain down-ward force on the ring compressor to prevent ringstrom expanding before entering the cylinder bore.6. Stop after the ring compressor pops free, and checkthe connecting rod-to-crank journal alignmentbefore pushing piston into place. 7.
