(4) Install pump pulley using tool J-25033 (fig. 2L-
50).
(5) Install pump belt and adjust belt tension. Refer
to Belt Tension Adjustment.
(6) Fill pump reservoir with power steering fluid
and bleed air from system. Refer to Fluid Level and
Initial Operation.
Beit Tension Adjustment
Use Tension Gauge J-23600 to measure belt tension
(fig. 2L-51). When using the gauge, position it at the
center of the longest belt span to check tension. If check-
ing tension on a notched belt, be sure the gauge finger is
seated in one of the notched grooves in the belt.
(1) Loosen pump adjusting bracket bolts.
(2) Pull back on adjuster bracket with a 1/2-inch
drive breaker bar until belt is tight. Tighten adjusting
bracket bolts.
(3) Measure belt tension with gauge J-23600 (fig.
2L-51).
(4) Tighten or loosen pump belt unitl desired belt
tension is obtained. Refer to Specifications for belt ten-
sion figures for various models.
(5) Tighten all pump mounting and adjusting
bracket bolts to 30 foot-pounds (41 N*m) torque after
adjusting belt tension.
Row Control Valve
Removal
(1) Position drain pan under engine.
(2) Disconnect pressure hose at pump. Cap hose to
prevent dirt entry and excessive fluid loss.
(3) Remove pump union fitting and O-ring (fig. 2L-
52). Discard O-ring.
(4) Remove flow control valve and spring using pen-
cil-type magnet.
Installation
(1) Lubricate replacement flow control valve and
union fitting O-ring with power steering fluid.
(2) Insert hex-end of flow control valve in replace-
ment valve spring.
(3) Install assembled valve and spring in pump
bore, spring-end first.
(4) Install replacement O-ring seal on pump union
fitting and install fitting in pump. Tighten fitting to 35
foot-pounds (47 N»m) torque.
(5) Connect pressure hose to pump. Tighten hose
fitting to 35 foot-pounds (47 N*m) torque.
(6) Fill pump reservoir with power steering fluid.
(7) Start engine and check for leaks. Repair any
leaks as necessary.
(8) Bleed air from power steering system. Refer to
Fluid Level and Initial Operation.
(9) Remove drain pan.
