POWER STEERING

Fig. 5-9 Measuring Drag Link Height
CAUTION: Bending pitman arm must be done
very carefully to avoid internal stresses and
must be performed cold, with a round tool
placed in middle of arm. Do not bend unless
proper height cannot be obtained by moving
gear. All adjustments for parallelism should
be made at idler arm end if possible. Do not
attempt to bend pitman arm while it is attached
to the steering gear since this may damage
pitman shaft bearing.
6. Steering Column to
Gear Alignment
Whenever steering column or steering gear is
removed or loosened for service, alignment of
these two units to each other should be checked.
Proper adjustment between these two units is
essential to prevent side loading on upper steering
shaft lower bearing and stub shaft of steering
gear. Poor steering returnability, transmission
of steering gear noises through steering column,
and excessive wear of valve lands on valve bore
in housing result from misalignment of steering
shaft with steering gear stub shaft.
Alignment of steering column to gear should be
gaged on position of flexible coupling.
The steering column and gear are correctly
aligned when flexible coupling is resting with
rubber disc flat and safety pins centered in " C "
slots of upper flange. The pins should also extend
equally at both locations beyond edges of flange
slots, Fig. 5T10.
