9·9. Adjustment of Rear Road Clearance
Rear road clearance can be adjusted
also by changing engagement of inner
and outer serrations of torsion bar.
Since numbers of teeth of inner and
outer serrations are 37 and 34 respec·
tively and distance between torsion
bar center and wheel center is approx.
400 mm (15.75 in), shifting the match-
ing of inner or outer serration by one
pitch causes change in rear road
clearance by 68 mm or 74 mm (2.68
or 2.91 in) respectively.
Therefore, by shifting the matchings
of inner and outer serrations in oppo-
site directions, various adjustments can
b.e made.
Adjustment with rear suspension
mounted on the vehicle can be made
as follows.
1) Measure rear road clearance, and
determine numbers of teeth to be
shifted on inner and/or outer serra·
tions.
2) Remove the bolt which attaches
shock absorber to the body at the top
of shock absorber.
3) Jack up the vehicle body and
remove wheels.
4) Remove lock bolt of outer bush·
ing.
5) Remove three bolts connecting
outer arm and inner arm, with brake
drum supported by a jack or the
like to prevent brake hose from
damage.
6) Mark on outer bushing, cross-
member and torsion bar so as to
identify their original positions.
7) Measure vertical distance between
end of outer arm and vehicle body.
8) Pull out outer arm together
with torsion bar until inner serration
is disengaged completely.
9) Rotate torsion bar and outer arm
to shift matching of inner serration
by appropriate pitches, and engage
inner serration with crossmember.
10) Pull out outer arm from torsion
bar, and rotate outer arm to opposite
direction to shift matching of outer
9-24
serration by appropriate pitches.
NOTE:
Pay attention not to disengage inner
serration of torsion bar from cross·
member.
11) Install outer arm to trosion bar
and crossmember, and then measure
in the same manner as step 7).
Change in this distance shows a
half of change in rear road clearance
caused by adjustment.
12) Connect outer arm and inner
arm by installing three bolts.
13) Carry out same work on the
other wheel.
14) Install wheels, and put the
vehicle down on the ground.
15) Install shock absorber. to vehicle
body.
16) Install lock bolt of outer bushing.
17) Confirm that rear road clearance
is properly adjusted.
