6. Remove seal/expander assembly (13) from
the piston.
NOTE: It may be necessary to apply heat to
break the bond of the sealant between piston (12),
and rod (1) before the piston can be removed.
Refer to paragraph 9.5.a.
7. Remove capscrew (15) and pull the piston
from rod.
8. Remove O-ring (11) and backup rings (10)
from inside of the piston.
9. Pull spacer (8) and head (5) from the rod and
remove snap ring (9) from inside of the
spacer.
10. Remove O-ring (7), backup ring (6) wiper (2),
rod seal (3), and )-ring (4) from the head.
IMPORTANT: Do not attempt to reset the extend
cylinder counterbalance valve cartridge. If re-
placement is necessary, replace the cartridge with
a new one.
4. Using a pin spanner wrench, unscrew the
head (5, Fig. 9.23) from the tube (16).
IMPORTANT: Protect the finish on the rod at
all times. Damage to the surface of the rod can
cause premature seal failure.
5. Pull the rod and piston assembly straight out
of the tube.
IMPORTANT: When sliding the rod and piston
assembly out of the tube, be careful so that gland
threads in the tube do not damage the piston (12).
Keep the rod in line with the tube barrel to prevent
binding.
