REPAIR INSTRUCTIONS, PART 1
The hole in the upper connecting rod bearing
must be aligned with the oil passage in the
connecting rod. Failure to heed this caution may
result in severe engine damage.
5. Position the upper bearing insert into the
connecting rod. Align the tab in the bearing
with the notch in the rod.
6. Apply a light coat of clean engine oil to the
bearing surface.
7. Apply a light coat of clean engine oil to the
inside surface of the cylinder liner.
8. Using ring compressor, J 48205, slide the
piston and rod assembly into the cylinder
until the compressor contacts the top of the
liner.
The arrow on top of the piston and the word
FRONT on the connecting rod must be facing the
front of the engine. This ensures that the notch in
the lower rim of the skirt clears the piston cooling
nozzle.

9. Make sure the connecting rod is aligned with
the crankshaft journal.
10. While using a hammer handle to push the
piston through the tool, apply pressure to the
ring compressor tool to maintain contact with
the cylinder liner. Continue pushing the
piston until the top ring has passed into the
cylinder liner.

Figure 259 — Pushing Piston into Cylinder Liner
Do not use excessive force on the piston. High
resistance indicates an incorrectly aligned ring.
Remove the piston assembly, correct the
problem, and then reinsert it. Make sure the
compressor tool remains in contact with the
cylinder liner until the piston clears the tool.
Failure to heed this caution may result in severe
engine damage.
Be sure that the piston cooling nozzle is aligned
with the notch in the lower end of the piston skirt.
Failure to heed this caution may result in severe
engine damage.
