STEERING COLUMN (FLOOR SHIFT)

The steering column with a floor mounted gearshift is basically the same as previously described. Standard columns and service procedures are identical except as described below.

* In place of rotating shift housing, there is a plastic shroud which is fixed to lock housing. Shroud covers jacket and lock inhibitor assembly. It is held in place by a tab that fits under side cover and one screw. Shroud can only be replaced by removing lock housing from jacket.

  1. The lock inhibitor assembly consists of a lever that engages
    lock levers (preventing locking of steering shaft)
    , a button
    to operate lever and a return spring. Assembly is attached to
    lock housing in same location as shift gate is on column
    shift. Lower steering shaft bearing is mounted in an aluminum
    support.

  2. A spring is attached between shift housing and column jacket.
    This spring keeps housing rotated counterclockwise against
    rubber bumper.
