1. Position the spring for the oil control piston ring in
the oil ring groove in the piston body assembly.
2. Position oil control piston ring (3) over the spring.
Position the oil control piston ring so that the gap
is 180 degrees from the joint in the spring. Install
theoilcontrolpistonringonthepistonwithTooling
(B).
3. Use Tooling (B) to install intermediate piston ring
(2) with the side that has the identification “UP-2”
toward the top of the piston.
4. Use Tooling (B) to install top piston ring (1) with
thesidethathastheidentification “UP-1 ” toward
the top of the piston.
5. Position top piston ring (1), intermediate piston
ring (2), and oil control piston ring (3) so the gaps
are 120 degrees from each other.
6. Check the clearance between the ends of top
piston ring (1), intermediate piston ring (2), and
oil control piston ring (3). Refer to Specifications,
“Pistons And Rings”.
7. Position piston body assembly (4) on connecting
rod (6). Apply clean engine oil to connecting rod
pin (7) and install the connecting rod pin. Install
pin retainers (5) with Tooling (A).
8. Install upper connecting rod bearing (8) in
connecting rod (6).
Note: Ensure that the bearing locking tab is located
in the notch of the connecting rod.
9. Install lower connecting rod bearing (9) in
connecting rod bearing cap (10).
Note: Ensure that the bearing locking tab is located
in the notch of t
he connecting rod bearing cap.
10. Ensure that the dowels are installed in the
connecting ro
d bearing cap.
End By:
a. Install the pistons and connecting rods. Refer
to Disassembly and Assembly, “Pistons and

NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Note: Instal
l the connecting rod bearings dry
when clearance checks are performed. Refer to
Disassembly and Assembly, “Bearing C learance -
Check”. App
ly clean engine oil on the connecting rod
bearings for final assembly.
1. Apply clean
engine oil to the cylinder liner bore, to
the piston rings, and to the outer surface of the
piston.
Note: Ensure that the connecting rod and pistons are
installed in the correct cylinder.
