rod (118). Remove rod (114) from bottom cap
(116).
b.
Remove seal (115) from bottom cap (116),
using a wood or plastic pick. If bottom cap bearing is excessively worn, replace bottom cap
(116).
10. Inspect piston rod (114) and inner surface of cylinder (108) for wear, scratches, or other damage.
Replace as necessary.
If piston (112) is still attached to rod (114) and
either part needs replacement, place flats of rod in
vise and unscrew nut (111). Disassemble piston.
Reassembly
1. Install rod seal (115*) in bottom cylinder cap (116)
with its lips facing up toward the cylinder. Lubricate
piston rod (114) and bearing (inside the bottom cap)
with oil (not grease). Insert rod through bottom cap,
making sure it doesn’t catch the lips of seal (115).
2. Apply Loctite to connecting rod (118) threads, then
screw connecting rod into bottom of piston rod
(114).
3. If piston was removed, place connecting rod (118) in
a vise so piston rod (114) faces up. Apply Loctite to
piston rod (114) threads, reassemble piston assembly (126, 112, 126), and torque nut (111) to 120 ft-lb
