(4) Position rotor on thrust plate and align shaft
bores in rotor and plate.
(5) Assemble pump shaft, thrust plate, and rotor.
Insert splined end of shaft through thrust plate and
rotor and install shaft snap ring (fig. 2L-56). Do not
overspread snap ring..Open it only enough to install it.
(6) Install assembled thrust plate, rotor, and pump
shaft in pump body bore.
(7) Align thrust plate dowel pins with dowel holes
in pump ring (fig. 2L-57).
(8) Install pump ring on dowel pins and over rotor
and thrust plate. Pump rotation arrow on pump ring
must face upward when ring is installed (fig. 2L-58). Do
not displace end plate O-ring during ring installation.
(9) Install rotor vanes in rotor slots (fig. 2L-59).
Rounded edges of vanes must face outward.
(10) Lubricate pressure plate outside diameter and
chamfered surface with petroleum jelly.
(11) Install pressure plate on thrust plate dowel pins.
Spring groove in plate must face upward when installed
(fig. 2L-56).
(12) Seat pressure plate using large socket. Position
socket on plate and press downward approximately 1/16
inch (1.58 mm) to seat plate.
(13) Lubricate remaining end plate O-ring seal with
petroleum jelly and install O-ring in second (center)
groove in pump body bore (fig. 2L-55).
(14) Install pressure plate spring on pressure plate.
Be sure spring is seated in plate spring groove (fig. 2L-
58).

(18) Install mounting stud O-ring seals in pump body
counterbores (fig. 2L-55). Lubricate O-rings with petro-
leum jelly before installation.
(19) Lubricate reservoir O-ring seal with petroleum
jelly and install seal in pump body seal groove.
(20) Lubricate O-ring seal surface of pump reservoir
with petroleum jelly and install reservoir on pump body.
Be sure reservoir is aligned with mounting stud bores
and seals.
CAUTION: Be careful to avoid displacing or damaging
any of the O-ring seals during installation. Use a wood
or plastic tool to keep the reservoir seal in its seal groove
when installing the reservoir.
(21) Install mounting studs. Tighten studs to 35 foot-
pounds (47 N»m) torque.
(22) Lubricate pump union fitting with petroleum
jelly and install O-ring seal on pump union fitting.
(23) Install pump union fitting in flow control valve
bore and tighten fitting to 35 foot-pounds (47 N»m)
torque.
(24) Install pump pulley using tool J-25033 (fig. 2L-
50).
(25) Install pump. Refer to Pump Installation.
(26) Fill pump reservoir and bleed air from system.
