Examination
Clean the spring leaves thoroughly using paraffin.
Check thrust buttons for excessive wear and, If
necessary, replace with new ones.
The spring leaves should be examined for cracks,
particularly If one of �hem is fractured.
A crack will often show due to exudation of paraffin
along the line of the crack.
All faulty leaves should be replaced by new ones.
The "setting up" of spring leaves Is not recom­
mended and In the case of a weak spring a new or
factory reconditioned assembly should be titted.
To rebuild
Before rebuilding the spring the leaves should be
thoroughly lubricated with graphite grease.
Rebuilding is the reversal of the dismantling
Instructions, but alignment of the leaves wlll be
greatly facilitated If a length of steel rod of suitable
diameter Is Inserted through the dowel bolt hole,
otherwise damage to the threads of the dowel bolt
may occur.
When the leaves have been fully pressed home the
rod should be removed, the dowel bolt fitted, and
the nut tightened. Carefully refit the bundle clips
together with the rubber packing. The clamp bolt
should not be over-tightened as damage to the
rubber packing and distortion of the clip may result.
Before refitting the spring to the chassis, check that
the leaves are lying flush on each other.
Bushes may be pressed out of the spring or frame
for renewal purposes.
The use of a suitable withdrawal tool Is recom­
mended.
Front eye bush (eccentric type)
If a new front eye bush Is fitted It Is Imperative
that It Is pressed in so that the pivot pin location
Is at the top of the spring eye.

A tolerance of
±
-h
In. (·8mm) must not be ex­
ceeded. To ensure that this is maintained, the
spring should be scribed as shown at (A) In Fig. '4
before fitting.

To check rear sprin1 camber
Spring camber is the difference height In between
, the top of the master leaf and a straight line joining
the spring eye centres.
As will be appreciated this varies according to the
weight carried In the vehicle.
In order to check the rear spring laden camber
LOAD THE VEHICLE BY PLACING WEIGHTS
TO THE VALUE SHOWN IN THE GENERAL
DATA SECTION UNDER THE HEADING "REAR
SUSPENSION".
Stretch a length of thread between the spring eye
centres and measure the distance between the top
of the master leaf and the thread.
Positive camber means that the line of the thread
will be ABOVE the main leaf of the spring. Reverse
or negative camber means that the line of the
thread will be BELOW the main leaf.
For correct spring camber see "General Data" at
the beginning of the manual.
