(2) Remove adjuster screw and shim from pitman
shaft T-slot (if not removed previously). Retain screw
and shim for end play check.
Cleaning and Inspection
Clean the housing and pitman shaft with solvent and
dry using clean cloths or compressed air. Inspect the
housing for cracks, porosity, damaged threads and gas
ket surface scoring or distortion. Inspect the pitman
shaft bore contact surface and sector teeth for wear,
pitting, or other damage.
Insert the pitman shaft in the housing bore and check
for shaft or housing bore wear. The shaft should exhibit
a smooth, bind free fit and not display any visible side
play when installed in the bore. If the shaft appears
loose and is not visibly worn, trial fit a new shaft in the
housing bore. If the new shaft is also loose, replace the
housing. However, if the new shaft fits properly, replace
the pitman shaft.
Measure adjuster screw fit and end play in the pitman
shaft T-slot. When installed, the screw must rotate
freely and not bind in any position. Measure end play by
inserting a feeler gauge between the screw head and T-
slot surface (fig. 2K-12). End play must not exceed 0.002
inches (0.05 mm). If end play exceeds specified limit,
select and install a replacement shim that will provide
the specified clearance. Shims are furnished in four
thicknesses; 0.063, 0.065, 0.067 and 0.069 inch (1.60,1.65,
1.70 and 1.75 mm) and are available in kit form.
Inspect the wormshaft upper bearing and bearing cup
for wear, looseness, flat spots, pitting, cracks, or other
damage. If either the bearing or bearing cup is damaged,
both parts must be replaced. If the cup is loose in the
housing, trial fit a new cup. If the new cup is also loose,
replace the housing. If the new cup fits properly, replace
only the bearing cup.
