CHECKING AND ADJUSTING THE FRONT AXLE USING AN OPTICAL ALIGNMENT GAUGE
IMPORTANT The checks and adjustments described in this operation are carried out with a BEM-MULLER 665
JUNIOR kit

the procedure remain the same when carried out using another type of equipment. In that case,
take account of the instructions of the other kit I. PREPARING THE VEHICLE

IMPORTANT NOTE :
To carry out this adjustment it is essential to
use tool 6312 T class 2 which is required for fitting
lower wheelorm on front axle.
a) Remove :
wheel,
lower arm and castor angle adjusting shims (3 )
b)
Determining distribution of shims :
NOTES :
A minimum of 1 shim should be set on each
side of the wheelarm.
- Movement of
1 mm will vary castor angle by
15’.
Total thickness of shims fitted must corres-
pond to the total thickness of shims found on
dismantling, in order to maintain the correct
assembly of the wheelarm in axle unit.

whirls. set /he s,rering 10 Ihv straight line positim~( see chapters I and II )
IMPORTANT NOTE
When the steering has been set in I( straight line >) position, (the marks in line with zero
on the sectors of the turntables
1 steering wheel and front wheels must not be touched throughout the whole of
the testing operation.
2. Check readings Ll and L2 ( see chapter I ).
3. Adjust the length of the telescopic rods approximately according to the front track of the vehicle, both rods
being of the some length.
IMPORTANT : Place the rods on either side of front axle so that they are parallel to each other and perpendicular
to the longitudinal axis of the vehicle and the overall
distance between them is exactly 2.48 meters.
The rods need not necessarily be at equal distance from the axle but the spacing between them is essential.
4.
To make the test :
Pivot one of the two projectors towards the front rod hnd read off on the graduated rule thr value indicated by the
luminous mark. Then pivot projector towards the rear rod and move this laterally until the snne reading is obtained
as for the front rod.
Repeat this operation with the other projector, pivotting it successively towards the rear rod and then towards
the front
rod and each time note the readings indicated by the luminous mark.
The reading shown on the rem alignment rod should be 1 to 4 graduations greater than the reading shown on the
front alignment rod which corresponds to a
toe-in between 1 to 4 mm.
NOTE Never adjust the lens between the two front and rear readings.

CHECKING THE REAR AXLE USING OPTICAL EQUIPMENT
NOTE For detailed instructions on the use of optical equipment see front axle checking operation (Op. MA. 410-O)
1. Checking’axle alignment :
L
(11 With the vehicle on the turntables (engine running and manual height control in normnl runniup position)
& ( turntables marks at zero 1, place a graduated plate ( 1 i on the vertical centreline of each front wheel.

: b) Fit the projector unit on ca<-h rcnl uhccl.
I”
c i Swivel the projectors towards the graduated plate. Focus luminous index on graduations.
2 d ) Push the graduated plates against their stops ( 2 ).
The alignment of the
rear axle is correct when there is no difference in the reading between left-hcnd
52 and right-hand sides.
