6. Grease the piston (89), o–ring (62*), and inside of the
cylinder (81). Place the cylinder upside down on a flat
surface. Place the o–ring around the piston; the o–
ring is larger than the piston groove. Install the piston
in the cylinder so the excess of the o–ring fits into the
one of the notches on the flange of the cylinder. Use
your fingers to push the o–ring out of the notch and
seat it in the piston groove. Push the piston into the
the cylinder to hold the o–ring in place.
7. Regrease the inside of the cylinder (81), the trip rod
(33) and the piston stud (73). Be sure the gasket (53)
is properly located on the base (2).
8. Guide the piston assembly and cylinder into the
base, aligning the cylinder and base correctly. Install
the lockwashers (39) and screws (44) snugly.
9. Install a washer (54*) and v–packing (55*) in the
bearing (1) so the lips of the v–packing face down in
the cylinder. Install the o–ring (51) on the bearing.
10. Install the bearing (1) in the cylinder throat.
11. Push the piston up and thread the trip rod nut (65)
loosely onto the trip rod. Use a 1 in. socket wrench
to tighten the bearing (1) into the cylinder.
12. Install the dampener pad (61) and washer (60) in cyl-
inder throat.
