IMPORTANT: Reattach each rod cap to its rod
as soon as the piston is removed. Each cap is
unique and can only be installed on its mated rod.
Do not allow rod to contact inside surface of cylin-
der or crankshaft.
IMPORTANT: Identify all internal components
so that if reused, they can be reinstalled in their
original positions.
Repeat steps for each remaining piston and con-
necting rod.
Use an appropriate ring expander to remove all
piston rings from pistons. Discard the rings.
Remove wrist pin retaining rings. Discard retaining
rings.
The wrist pin fit is loose on both sides. Push the
wrist pin through to free the piston from the con-
necting rod. If necessary, use Wrist Pin Pressing
Tool, P/N 326356, to remove the wrist pin bearing.
Be careful not to lose any of the 28 needle bear-
ings or the two wrist pin washers. If any of the
bearings are worn or lost, replace all 28 bearings
during reassembly.
Crankshaft Removal
Carefully lift crankshaft straight up and remove
from crankcase.
Remove upper seal from crankshaft. Discard the
seal. A new upper seal must be installed on
assembly.
