FRAME
SWINGING
FOR#
The swinging fork
is
pivoted to the main frame by a ground, hollow spindle. Two
phosphor bronze bushes are pressed into the fork bridge lug to provide a bearing
surface for the fork to swing on. The spindle
is
a drive
fit
into the frame lug
and a working
fit
in the fork bushes. To retain the spindle in position, a rod
is
passed through the hollow in the spindle and
at
each end a retainer cap
is
made
captive, by
a
nut screwed on the rod end.
Between the bridge lug and frame lug
on the R.H. side,
a
spacing washer
is
fitted in order to obtain the clearance which
should be between
.OOOSa.
0.0065" (0.013
-
0.16 mrn.). A grease nipple
is
fitted to
the frame to provide access for grease to the bearing by means of a grease gun.
(See Routine
Mai~tenance).
Under average conditions the life of the bearing bushes
is
approximately 20.000 miles
(30,030 kms.). The operation required to replace the bushes
is
of
a
major type which
calls for the removal
oI
the primary chaincase assembly, gearbox covers, rear wheel
and mudguard assembly. If the private owner attempts this work, he should ensure
that he has
suffirient tools available to complete the work. Details of rernoving the
above mentioned parts will be found by referring to the index on page
210.

UNITS
These units are completely self-contained and are known under the type number
S/MDA/4/4, which should always be referred to in any correspondence.
During the norhal life of the unit the maintenance
is
negligible: such parts
as
tile
main spring and rubber bushes can be easily changed by the owner, but shr.:ld the
hydraulic unit be suspected, no attempt should be made to dismantle
it.
The
complete units should be returned
to
a Lucas-Girling Depot or the manufacturers.
where a service unit can be obtained, or the fault in the suspected unit rectified.
