REPAIR STEERING PUMP (Continued).
i.
Inspect the valve plug (17) torque by first
placing the control valve (19) in a bench
vise, then tightening the vise enough to
prevent the plunger from turning. Use a
torque wrench and appropriate socket to
check the torque of the valve plug (17). The
plug should be torqued to a value of 5 to 6 lb
ft.
ASSEMBLY
ASSEMBLE STEERING PUMP
NOTE
Tools for installing needle bearings can be made from round tubular stock. The
outside diameter of the round stock must be slightly smaller than the outside
diameter of the needle bearing.
a.
Press needle bearing (26) into body (1),
using a needle bearing pressing tool (noted
above) and an arbor press.
NOTE
A shaft driver must be used to insure installation of the shaft seal without damage.
b.
Position the shaft seal (27) with spring
side of seal facing body (1). Press shaft seal
(27) in place until it engages the shoulder
within the body.
c.
If removed or found defective, press a
new bearing (23) on shaft (22), using an
arbor press. (All force should be applied to
the inner race of the bearing.)
d.
Install the small retaining ring (25) in place
within its groove on the shaft (22). (The
sharp break edge of the retaining ring must
be facing the bearing at assembly.)
