Figure 38 — Sizing the Piston Ring
• P u sh J 2 4 6 0 8 -5 ( in s ta lle r )
J 24608-2 (guide).
• If the piston ring is off-positive in the groove,
reposition by moving with a fingernail or a
blunt-edge tool.
• J 24608-5 (installer) will keep the J 24608-2
(guide) inside when the piston ring is installed
on the piston (32).
• Remove the guide from the installer and do
not store the guide in the installer because the
seal will be stretched and weakened during
storage. This can cause the seal not to hold
the ring installer segm ents tight enough to the
J 24608-2 (guide) when installing the piston
ring (33) to the piston (32).
• Lubricate the piston ring (33) area with 525
viscosity refrigerant oil.
• R otate the piston (32) and ring (33) into
J 24608-6 at a slight angle until the piston is
inserted against the center stop of J 23608-6.
