REPAIR INSTRUCTIONS, PART 1
RING INSTALLATION
Identification markings on the rings should face
the piston top. The keystone ring goes in the top
ring groove.
Follow the directions on each piston ring packet.

Figure 211 — Piston Rings
1. To prevent distortion, use the proper size
piston ring expander, to insert the rings in
the grooves.
2. Stagger the ring gaps so that they are not
aligned and none is directly over the
wrist-pin bore.

Assembly
[212 LP & NP]
Be sure that the piston and rod assemblies are
clearly marked with their cylinder location. They
must be returned to the same cylinder from which
they were removed. Failure to heed this caution
may result in severe engine damage.
1. Insert a snap ring in one of the wrist pin
grooves of the piston.
2. Insert the connecting rod in the piston
assembly.
Align the FRONT mark on the connecting rod with
the FRONT mark on the piston. Refer to
Figure 207.
