Piston
1. Rotate the flywheel until the piston reaches Top
Dead Center (TDC).
2. Using a needle-nose pliers, remove the piston pin
retainer from the groove in the piston.
See
Figure 10-39.

Piston
3. Gently push the piston pin out of the piston from the
flywheel side. See Figure 10-40.
Note:
If the piston pin sticks in the piston, remove the
piston together with the connecting rod. Remove
the assembly from the engine and hammer out
the piston pin.

Piston
Connecting Rod
1. Lay the engine, on its flywheel side, on a work
bench.
2. Move the flywheel until the piston reaches the
Bottom Dead Center (BDC) of its stroke.
3. Loosen the six hex cap head screws of the oil
cooler housing and remove it from the engine. If
the screws are tight, tap them with a hammer and a
flat-faced
punch
to
loosen
them.
See
Figure 10-41.
4. Using a 13 mm socket wrench, unscrew the two
connecting rod nuts. Pull the connecting rod cap
downwards while pushing the connecting rod
upwards. See Figure 10-42.
5. If the two half shells of the connecting rod need to
be
reinstalled,
mark
them
so
that
proper
repositioning occurs during reassembly.
