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.
Refer to Figure 173.
1. To prevent distortion, use the proper size
piston ring expander (PT6587) to place rings
in the piston grooves.

2. Stagger the piston rings so that no ring gap
is directly over the wrist pin bore, and no ring
end gaps are aligned over each other
(Figure 174).
