Movable Steering Columns: Disassembly: Notes
NOTE:
Disassembly and assembly procedures for the "Tilt-Wheel" and "Tilt-Telescope" systems are identical except for the upper shaft and yoke procedure on the "Tilt-Telescope" steering wheel which necessitates one additional step. This additional procedure is called out in step 13 of the following.
WARNING:
Components and fastenings mentioned in the following steps are important in that a failure or misadjustment could affect the safety of the vehicle, the performance of vital systems, or result in major repair expense. If a component or fastening must be replaced, it must be replaced with one of the same part number or an equivalent part. DO NOT use a replacement part of lesser quality or substitute design.
With steering wheel removed from column and column removed from car, mount assembly in vise either by clamping weld nuts on column or by attaching a suitable holding fixture to the column and proceed as follows:
- Remove signal switch wire protector and remove cover. Remove tilt release lever, turn signal switch lever. Push hazard warning plunger in and remove hazard warning knob. Remove upper shaft lever from bowl.
- Use a suitable tool (Kent Moore J-23131) to depress lock plate and pry snap ring from groove. Discard snap ring, since a new ring must be used in reassembly. Remove cancelling cam and spring.
- Wrap tape around the upper part of turn signal switch connector and wires and remove switch. Place shift bowl (or shroud) in LOW position. Pull switch straight up.
- If the lock cylinder is to be removed, place it in the ACCESSORY position. Use a thin tool in the slot next to the switch mounting screw boss (right hand slot) to depress the spring latch at bottom of slot and remove lock.
- To remove the buzzer switch (if the lock cylinder is not removed), place lock in RUN and pull buzzer switch straight out of housing.NOTE: Do not pull on switch terminals. Use bent wire or needle nose pliers to pull on switch clip. Next, remove housing cover.
- Use tilt release lever and place steering wheel in full UP position. Remove tilt spring retainer by inserting a screwdriver in retainer slot. Depress retainer and turn approximately 1/8 turn counterclockwise until ears align with grooves in housing. Remove spring and guide.NOTE: Be careful when releasing spring as it is under high compression.
- With tilt column in neutral position, push upper steering shaft in sufficiently to remove steering shaft inner race, seat and race.
- Remove lower steering shaft flange, no-back washer (if used), spacer, spring, clip and bearing adapter assembly at lower end of the mast jacket.
- Place ignition switch in ACCESSORY position and remove. Remove neutral-start switch.
- Use a suitable pivot pin removal tool (J-21854) to remove both pivot pins.
- Install tilt release lever, place in full UP position and disengage lock shoes. Remove bearing housing assembly by pulling upward to extend rack full down and moving housing assembly to the left to disengage rack from actuator. Remove actuator rod assembly. Remove steering shaft assembly from upper end.
- Disassemble steering shaft assembly by removing centering spheres and anti-lash spring.
- Disassemble upper steering shaft, locking wedge, locking rod and bumper from upper yoke.NOTE: This operation necessary only on "Tilt-Telescope" wheels.
- Remove support assembly from column. Remove shift tube retaining ring and thrust washer.
- Use suitable tool (Kent-Moore J-23072) to remove shift tube from bowl. Pilot the adapter in upper end of shift tube and force tube from bowl. Exercise care not to jam lower shift lever into "T" slot on lower end of mast jacket while removing tube.CAUTION: Never hammer or pull on lower or upper shift tube. Plastic injection may be sheared.
- Remove shift tube assembly from mast jacket from lower end. Remove lock plate and wave washer.
