Fit new sealing ring (16) into base then screw liner (15) into base. Tighten to 75 ft lb.
Fit pump plunger into pump barrel (12) until center groove is flush with top of barrel.
Refit filter (14) and new base gasket (13). Do not use gasket sealant.
Ensure that center groove in plunger (11) is flush with top of barrel (12), then with assembled base and
liner flat on bench with toe pointing away from you, lift body (10) with one hand, and holding quadrant (44)
in upper position with other hand, carefully lower body over liner, turning it at an angle of approximately
45 so it does not interfere with plunger.
When body has cleared plunger, lower it down square to base, and allow sealing ring (53) to rest on liner
(15) with quadrant still held in upper position. This will allow the body to rock backwards and forwards.
Push the body to its foremost position and slowly push quadrant into lower position then pull body
backwards approximately '12 in (12mm).
Grooved pin (46) should now be located under retaining clip (56).
Still holding body in backward position strike top of body with soft-faced hammer to enable it to ride over
seal and drop onto base gasket (13).
To check for correct assembly operate quadrant up and down several times and listen for air,
pulsing from pump, at oil filler hole.
(29) Fit the six base screws (8) and tighten sequentially to 65 ft lb.
Assemble swivel cradle seat (7), swivel cradle (6), lock washer (5) and cap pin (4). Tighten cap pin.
Replace keeper plate (3) but do not overtighten.
Fill with fresh, clean oil, approximately 2 5/8 pints (1 1/2 liters), to not more than 1 inch (25mm) above
mark on dipstick.
(33) Replace dipstick.
Remove any air from jack as follows:
Tighten release valve screw (1).
Insert operating handle (58) into quadrant (45).
Operate pump until ram has risen approximately 3 in (76 mm).
Unscrew release valve screw (1) no more than 1 to 1 1/2 turns.
Press down ram as far as it will go and listen for air.
Repeat steps (a) to (e) until all air has been expelled.
