Fig. 6—Removing Wormshaft and Ball Nut
Inspection
With the steering gear completely disassembled, wash
all parts in cleaning solvent. Dry them thoroughly with
air. With a magnifying glass inspect the bearings and
bearing cups for signs of indentation. Also check for any
signs of chipping or breakdown of the surface. Any parts
Fig. 8—Sector Shaft Bushings Installed—Chevy II and Corvette
that show signs of damage should be replaced.
Inspect all seals. Any seal that is worn or has been
removed should be replaced.
Inspect the sector shaft for wear and check the fit of
the shaft in the housing bushings.
Inspect the fit of the sector shaft in its bushing in the
side cover. If this bushing is worn, a new side cover and
bushing assembly should be installed.
Check steering gear wormshaft assembly for bent or
damaged shaft. Never attempt to salvage steering parts
by welding or straightening.
Repairs
Sector Shaft Bushing Replacement
1. Support steering gear housing in an arbor press and
press sector shaft bushing (2 bushings for Chevy II
and Corvette) from housing with Tool J-1614, in-
serted from lower end of housing as shown (fig. 7).
2. Press new bushing or bushings into position using
the same sector shaft bushing driver as used for
removal. Check position of 2 bushings for Chevy II
and Corvette in Figure 8.
NOTE: Service bushings are diamond bored to
size and require no further reaming.
Wormshaft Seal Replacement
If the wormshaft seal indicates need of replacement, it
should be removed and a new seal pressed into position.
A suitable socket pressing on outer diameter of seal may
be used.
NOTE: Care should be taken to insure that seal
is not assembled in a cocked position.
CAUTION: On Chevy II and Corvette vehicles
check the upper wormshaft bearing cup before
installing the new seal.
