STEERING 9-10
SECTOR SHAFT SEAL REPLACEMENT
A faulty seal may be replaced without removal of
steering gear from car by removing pitman arm as out-
lined under Maintenance and Adjustments--Steering Gear
Adjustments and proceed as follows:
1.
Loose lash adjuster lock nut and turn lash adjuster
screw several turns counterclockwise.
2.
Remove three cap screws holding side cover to gear
bushing.
3.
Pull side cover and sector shaft from gear housing
as a unit. Do not separate side cover from sector
shaft.
4.
Pull sector shaft seal from gear housing using
hooked tool or pliers.
5. Coat new seal with chassis grease and position in
sector shaft bore.
6. Place a socket or piece of pipe of suitable diameter
on top of seal and drive seal into bore by tapping
pipe or socket with soft hammer.
7. Install sector shaft side cover assembly, being care-
ful not to damage new seal with splines on end of
shaft; splines may be wrapped with a few turns of
tape to prevent this.
8. Install new side cover gasket and align side cover on
gear housing and install cap screw.
9. Perform steering gear adjustment and install pitman
arm as outlined under Maintenance and Adjustments.
STEERING COLUMN
All models are equipped with new energy absorbing
steering columns. The columns are of five basic designs
as follows:
1.
Syncromesh. The syncromesh column is used on
models with standard, column mounted, conventional
shift levers. The shift tube, within the outer mast
jacket, includes two lower shift levers for connection
to the transmission control linkage.
2.
Automatic and floor shift. This column is used on
models equipped with column mounted powerglide
shift levers, or models with floor shift. If the ve-
hicle has the column mounted powerglide shift con-
trol, the inner shift tube has a single lower shift
lever for connection to the transmission control
linkage. On floor shift models, no lower shift levers
are present on the shift tube.
3.
Tilt wheel option. The upper end and steering shaft
of this column is specially designed to accommodate
the optional tilt steering wheel.
4.
Standard Corvette Column. The standard Corvette
column is similar in design to the Automatic and
Floor Shift column used on other models, except
no shift tube is used. Other differences are pointed
out in the disassembly and assembly procedures for
Standard Corvette column.
5. Telescopic wheel option. The upper end and steering
shaft of this column is specially designed to ac-
commodate the optional telescoping steering wheel.
To perform service procedures on steering column
upper end components, it is not necessary to remove the
column from the vehicle. The steering wheel, horn com-
ponents, turn signal switch, upper housing with bearing,
shift control lever, hazard warning knob, and upper shift
bowl may all be removed with the column remaining in
the vehicle. When servicing the above components, omit
the removal procedure and proceed with the applicable
disassembly procedures. Because of the numerous dif-
ferences in steering column types, be sure to refer to the
set of instructions below which apply to the exact column
to be serviced:
CAUTION: The outer mast jacket, shift tube, _
steering shaft, and instrument panel column
mounting b
racket
are designed as energy ab-
sorbing units. Because of the design of these
components, it is absolutely necessary to handle
the column with care when performing any serv-
ice operation required. Avoid hammering, jar-
ring, dropping, or leaning on any portion of the
column.
Removal
1.
Disconnect steering column harness at connector.
Disconnect neutral safety switch and back-up lamp
switch connectors if so equipped.
Remove steering wheel as outlined in this section.
Remove nuts and washers securing flanged end of
column to steering gear. On Chevy H models, re-
move nut and clamp bolt securing lower end of steer-
ing column to steering gear.
Disconnect transmission control linkage, if so
equipped, from lower column shift tube, levers.
Chevrolet and Chevy II only: Remove screws at-
taching upper and lower mast jacket covers together.
On Chevrolet, remove screws attaching lower cover
to instrument panel (figs. 15 and 18). Remove lower
cover.
Chevelle only: Remove screws securing mast jacket
trim cover to instrument panel and remove cover
(fig. 15).
Corvette, only: Remove screws securing escutcheon
to instrument panel. Remove screws securing upper
and lower covers together and remove covers.
On Chevrolet and Chevelle columns with Powerglide
shift levers, loosen set screw at six o'clock position
at bottom of column and remove the transmission
shift indicator pointer (fig. 15).
