Installation – Piston Rings Procedures:
a.
Lubricate new piston rings and piston with engine oil before installing rings.
CAUTION
Do not overlap ends of oil control ring expanders. An overlapped expander will
cause oil control ring to protrude beyond allowable limits and result in
breakage when inserting piston in piston ring compressor.
Do not cut or grind ends of expanders to prevent overlapping. Cutting or
grinding ends will decrease expanding force on oil control rings and result in
high lubricating oil consumption.
b.
Install new wavy ring expander (Figure 12, Item 14) in oil control ring groove (Figure 12, Item C) in
piston (Figure 12, Item 10).
c.
Install new spiral ring expander (Figure 12, Item 15) in oil control ring groove (Figure 12, Item D) in
piston (Figure 12, Item 10).
