Ring Installation
Identification markings on rings should face top of
piston. The keystone ring goes in the top ring
groove.
Follow the directions on each piston ring packet.
Refer to Figure 5-15.
1. To prevent distortion, use the proper size
piston ring expander (PT6587) to place rings
in piston grooves.
Figure 5-15 — Piston Ring Expander PT6587
Refer to Figure 5-16.
2. Stagger piston rings so that no ring gap is
directly over wrist pin bore, and no ring end
gaps are aligned over each other.

ROD ASSEMBLY TO PISTON
Refer to Figure 5-17.
1. Install a retaining snap ring in one of the
piston pin retaining grooves.
2. Position connecting rod in piston assembly.
Make sure that the side of the rod marked
FRONT is facing forward. Ensure that two-
piece piston identification marks and
connecting rod identification marks indicate
that piston and rod are matched. They must
be returned to same cylinder from which
they were removed.
