Connecting rods
1. Check the fit of a new piston in the cylinder bore before
assembling the piston pin to the connecting rod.
2. Apply a light coat of clean engine oil to all parts.
3. Assemble the piston to the connecting rod, putting the
notch in the piston dome and the connecting rod on the
same side.
4. Start the piston pin in the piston and connecting rod (this
may require a light tap with a mallet). Using an arbor press
and Piston Pin Remover and Replacer T68P-6135-A, or
equivalent, press the piston pin through the piston until
the pin is centered in the piston.
Piston rings
Install the piston rings to the piston using a piston ring
expander.
Note
Never install the piston rings with hands.
Piston rings should be staggered on the piston to
make sure the piston ring end gaps are not aligned.
If new piston rings are to be installed, and no visible
cross-hatch marks remain on the cylinder wall, or
an unfinished cylinder wall, then the wall must be
refinished using a spring-type Cylinder Hone Set
T73L-6011 -A, or equivalent.

1. Oil all pistons, piston rings and cylinder walls before
installation.
2. Install protective rubber caps on the connecting rod studs.
3. Rotate the crankshaft journal to the top of its travel.
4. Check the piston rings for proper end gap positioning.
5. Install a piston ring compressor to the piston.
6. Remove the protective rubber caps.
7. Install a clean, dry upper connecting rod bearing.
