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 sequence and
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 If the turntables ore not flush
with the ground ( when not set in the ground ),
place a compensating chock, of identical
thickness to that of the turntables, under
each rear wheel.
b 1 Apply the hondbrake.

Downloaded from www.Manualslib.com manuals search engine 2: Fitting the alignment gauges :
a) Remove all hubcaps and the two detachable
rear wing panels.
b) Adjust the position of the magnetic feet
A so
that with supports in place, thr central help is
in the centre of the rim.
c ) Fix the projectors on supports ( tighten knurled
screw ) (finger tight only 1.
NOTE Great care should be taken in setting
up this equipment since the accuracy of the
tests depends on its correct adjustment
Connect projectors to on appropriate electricity
SUPPlY.
3. Obtaining S( straight line )I steering position :
IMPORTANT In order that the following checks
should be accurate, the zero setting of the turn-
tables must correspond exactly to the strnifih/
liwv position of the vehicle.
a) Place the magnetic supports C of the graduated
rule forward to its maximum extent against its
stop.
b) With the engine idling, set the manual control
to ,KJWRl n,n,,ir,ji posili, ,,,.
Check measurements Ll and L2.

Focus beams on grotuoted rules so that illu-
minated index is clearly shown on graduations.

Take the reading shown for each side of the
vehicle.

Remove projectors.
( Leave projector brackets in place ).

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.
