NOTICE: The rack and pinion gears are not service-
able items. If they are found to be damaged or
excessively worn, a new rack and pinion unit must

and pinion unit is made of alumi-
num and can be damaged if held otherwise.

Rack and Pinion Unit Replacement on page 60
Anchor in vice by clamping on the mounting ears of
the unit.
2. Disassemble rack and pinion unit (1) by first remov-
ing screw (13) and tensioner (2) to relieve pressure
on rack (3) and pinion (4) (Ref. Figure 17). Loosen
jam nut (5) and remove rack ball joint (6) from rack
extension (7). Cut wire ties (8, 14) securing bellows
(9) and slide bellows off rack extension. Pull rack (3)

inal location on rack extension and set jam nut hand
tight.
