5. Turning force
of box and column only. The
maximum permitted
turning force of the box and
column only (drag
link
attached to steering box
but allowed to slide freely
across idler) is 1.2kg
2.5lbs when test is carried out as in (2).
lf the force
is excessive, lubricate
universal joints
and check
thatthe drag link assembly is free to move. Repeat
test. lf still excessive remove
the steering box,
which can be removed
with the track rod still
attached.
TIME ALLOWANCE 5 mins.
6. Turning force to rotate
Steering Box input
shaft. With some form
of coupling (coupling from
'S'
type Steering Box) test the force required to
rotate the shaft; maximum prmitted
torque0.1 6kg
1.16ft lbs.
lf using an arm and spring balance as
shown the maximum force required
can be
calculated bv

arm length
in inches
These tests should be carried out with the
worm in the central position.
The initial force will
be 0.25 kg %lb greater
than the average pull-
force. lf excessive, remove
input shaft top bearing
cap and adjust the
bearing to give
0.OO to
0.05mm preload.

excessive and unable to adjust by the adjusting
bolt, replace steering box after contacting
the

which can adversely
affect the
turning force of the
Steering mechanism:

lf problems
are experienced
with wheel

axle it is necessary to check
the amount of weight applied to one half of the
wheel rim which should not exceed
