c. Cleaning
1. Discard all seals and backup rings. Replace
with a complete new seal kit.
2. Clean all metal parts in an approved cleaning
solvent such as trichlorethylene. Be sure to
carefully clean all cavities and grooves.
d. Inspection, Repair and Replacement
1. Check that the rod is straight. If the rod is
bent, install new rod.
2. Inspect inside of the tube for deep scoring and
other damage. If the tube is damaged,
replace with new tube.
3. Remove small scratches on the rod or inside
the tube with emery cloth of very fine grit. Use
the emery cloth with a rotary motion.
e. Assembly
NOTE: Follow general assembly instructions in
paragraph 9.5.c.
1. Install a new O-ring (10), backup ring (11),
wiper (2), rod seal (3), and step seal (17) on
the gland as shown in Fig. 9.12.
NOTE: Wiper lip should be toward outer end of
gland and rod seal lips (3) and the step of step
seal (17) toward the inner end of the gland. Use
tools that will not damage the seals. If the backup
ring (11) is not flat on both sides, the side with the
arc must be toward O-ring (10).
2. Fasten the rod eye in a soft-jawed vise. Place
a padded support below and near end of rod
to prevent damage to rod (1).
