h.
Install pins (13) on pressure plate (12). Place the rotor (8), ring (10) and vane (9) assembly over the pins on the
plate.
i.
Install pressure plate (7) against the rotor and ring. The porting in this plate will be 90 degrees from the other
plate (12).
j.
Carefully install the screws (6), being certain the outer edges of the ring (10) and plates (7, 12) are flush. Tap
with a plastic hammer if necessary to effect alignment. Torque screws (6) to 8-12 ft.-lbs.

Install o-rings (5) and back-up rings (4) in plates (7, 12). Insure that o-ring is positioned in the concave side of
the back-up ring.
I.
Assemble the hub adapter (17) on the pressure plate (12). Install o-ring (18), then back-up ring (19) on the
adapter. Grease with petroleum jelly.
m.
Clamp the body (27) in a vise with protective jaws. Install the cartridge assembly (3) on the shaft (21) with hub
adapter (17) toward the body. Tap the cartridge into position.
n.
Install o-ring (15) in the body and the teflon o-ring (14) in the cover (2), greasing liberally.
o.
Carefully install the cover (2), being sure the pin in pressure plate (7) engages the pin hole in cover. To check,
turn the cover 30 degrees in both directions and be certain the cartridge moves with it.
p.
Install bolts (1) and torque to 190-210 ft.-lbs. Remove motor from vise and install key (16) in shaft.

a.
Remove key (1) from shifting shaft. Remove drain plug (4) to drain lubricant.
b.
Remove cotter pin (2) and nut (3) to remove flange from shaft (40).
c.
Remove plug (8) and, with a wire, lift out spring (10).
