Movable Steering Columns: Disassembly: Notes
NOTE:
Disassembly and assembly procedures for the "Tilt-Wheel" and "Tilt-A-Scope" systems are identical except for the upper shaft procedure on the "Tilt-A-Scope steering wheel, which necessitates one additional step. This additional procedure is called out in step 10 of the following.
With steering wheel removed from steering column and column removed from vehicle, attach column holding fixture (C-4132) to jacket pads, clamp assembly in vise and proceed as follows:
- Remove tilt level and turn signal lever. Push hazard warning knob in and unscrew to remove. Remove ignition key lamp assembly.
- Install lock plate compressing tool (C-4118). If working on "Tilt-A-Scope" system, lock telescoping shaft with a set screw before installing tool. Depress lock and carrier to remove "C" ring. Remove tool, lock plate, carrier and spring.
- Remove turn signal switch screws, place shift bowl in LOW and remove switch and wiring. The buzzer switch can be pulled straight out of the housing. A flat spring wedges the switch toward the lock cylinder. (Switch may be removed without the removal of the lock cylinder). If cylinder is in the housing, it must be in the ON position.
- If the lock cylinder is to be removed, it is recommended that it be positioned at LOCK. Insert a thin tool into the slot next to the switch mounting screw boss (right hand slot) and depress spring latch at bottom of slot and remove lock.
- Remove housing cover, install tilt release lever and place column in full UP position. Remove tilt spring retainer. Insert Allen wrench in slot, press in approximately 3/16", turn approximately 1/8" counterclockwise until ears align with grooves in housing and remove spring and guide.
- Remove seat and upper bearing race. With ignition switch in LOCK, remove switch screws and switch.
- Use pivot pin Remover Tool (C-4016) to remove both pivot pins. Use tilt release lever to 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 roll pin and coupling assembly from lower end of steering shaft. Remove shaft assembly from upper end.
- Disassemble steering shaft assembly by removing centering spheres and anti-lash spring.
- Disassemble upper steering shaft, locking wedge, and locking rod from upper yoke, (this operation not necessary on "Tilt-Wheel" system).
- Remove bolts securing support to lock plate and remove support from end of column jacket. If necessary, remove attaching screws and shift gate from the support.
- Remove shift tube retaining ring. Remove thrust washer. Remove clip and bearing adapter from lower end of column jacket.
- The column jacket with shift tube and bowl are serviced only as an assembly.
