Assembly of Piston and Rods
Insert milled end of relief valve into lower pis-
ton rod, followed by spring and plunger. Press
new end plug into lower piston rod until plug
just contacts valve body. The plug must hold
valve, just tight enough to hold valve sta-

through oil passage at top of rack teeth.
NOTE
A suitable adapter will be required to press end
plug into place; otherwise, damage to rod will

duce a rattling or clattering sound when hy-
draulic pressure is applied. If plug is pressed
in too lightly, it will cause relief ports in valve
body to collapse and restrict plunger, creating
high back pressure. This can result in lack of
steering assistance and a hissing noise.
Remove all burrs from around end plug. In-
stall "0" ring on lower piston rod (with rack)
and install lower piston rod into end of piston
assembly opposite pin hole.
NOTE
Using snap ring pliers, install snap ring with
tapered side away from piston so tapered side
is visible after installation. Measure gap be-
tween ends of snap ring to make sure ring is
seated. The minimum permissible gap is 25/64
inch.
Make certain ports in end of piston rod
are not restricted by snap ring.
