7. If the bearing and guide (35) was removed, install it on
the upper housing (53) with the three screws (36)
(apply thread sealant).
8. Hold the flats of the trip rod with an adjustable wrench
and install the upper housing (53). The trip rod will
protrude from the top.
9. Slide the lower trip rod guide (37) and spring (45) onto
the trip rod. Install the spool (38) with the detent at the
top. Install the top spring (45) and guide (37) on the
trip rod. Install the top hex nut (46). Torque the nut to
82-88 in-lb (9.3-9.9 Nm).
10. Remove the adjustable wrench. Seat the upper
housing (53) onto the cylinder (29), so the tube fittings
align with those on the lower housing (25).
Reinstall the hydraulic tube (4) and
loosely
tighten the
compression nuts.
11. Replace the o-ring (49*) on the stop plug (48). Seat the
plug into the upper housing (53).
12. Install the end cap (47), using thread sealant on the
socket screws (51).
13. Lubricate the threads of the tie rods (57) and install
them with lockwashers (52). If the crown nuts (44)
were removed, reinstall them and torque them onto
the rods to 70-80 ft-lb (95-108 Nm).
14. Torque tie rods into base, apply thread sealant to tie
rod threads, then torque the tie rod nuts (19) to 70--80
ft-lb (95-108 Nm).
15. With the motor on its side, install one detent
assembly: the ball (43), guide (42) with the concave
surface toward the ball, spring (40*), o-ring (41) and
retaining plug (39). Torque the plug to 145--160 in-lb
(16--18 N.m). Repeat for the other side of the motor.
16. Slide the drip cover (18) onto the piston (30a) up to the
o-ring (17). Install screw (20) into the piston. Attach the
drip pan (16) to the base using screws (12).
17. Snugly tighten the compression nuts on the hydraulic
tube (4) and torque to 60--80 ft-lb (81--108 Nm).
18. Install the motor on the displacement pump.
Reconnect all fluid lines. Be sure the ground wire is
connected before operating the pump.
