of notches to tension the chain and maintain
correct wheel alignment. Do not forget to refit
the brake rod and adjust the brake so that the
wheel turns freely while the brake is off, while
at the same time only a small travel of the brake
pedal is necessary to put the brake on.
3. Removal of Brake Shoes for Replacement
Fitting New Linings, etc.
Remove the complete wheel as described
above, then remove the left-hand spindle nut,
chain adjuster and
permitting the complete brake cover plate with
operating cam, pivot pin, shoes and return
springs to be lifted off the hub spindle.
4. Replacing Brake Linings
Brake linings are supplied either in pairs
ready drilled complete with rivets, Part No.
37786BX (6 in. steel shoes) or 37787BX (7 in.
steel shoes), or ready fitted to service
replacement brake shoes, Part No. 38042 (6 in.
steel shoes) or 38043 (7 in. steel shoes). When
riveting linings to shoes secure the two centre
rivets first so as to ensure that the lining lies flat
against the shoe. Standard linings are Ferodo
MR41 which are drilled to receive cheese
headed rivets.
5. Removal of Hub Spindle and Bearings
To remove the hub spindle and bearings,
having already removed the brake cover plate
assembly and speedometer drive gearbox. Lift
out the felt washers and distance pieces then hit
one end of the spindle with a copper hammer or
mallet, thus driving it out of the hub, bringing
one bearing with it and leaving the other in
position in the hub. Drive the bearing off the
spindle and insert the latter once more in the hub
at the end from which it was removed. Now drive
the spindle through the hub in the opposite
direction, when it will bring out the remaining
bearing.
6. Hub Bearings
These are deep-groove single-row journal
ball bearings. The Skefko Part No. is RLS5.
Equivalent bearings of other makes are
Hoffmann LS7, Ransome and Marles LJ 5/8 in.,
Fischer LST
The bearings used are 5/8 in. i/d by 1.13/16
in. o/d by 5/8 in. wide. The Skefko Part No. is
RMS5. Equivalent bearings are Hoffmann MS7,
Ransome and Marles MJ 5/8 in. and Fischer
MS7.
7. Fitting Limits for Bearings
The fit of the bearings in the hub barrel is
important. The bearings are locked on the
spindle between shoulders and the distance
Section L7 Page 2
distance collar, thus
pieces, which in turn are held up by the cover
plate nuts. In order to prevent endways
pre-loading of the bearings it is essential that
there is a small clearance between the inner edge
of the outer race of the bearing and the back of
the recess in either end of the hub barrel. To
prevent any possibility of sideways movement
of the hub barrel on the bearings it is, therefore,
necessary for the bearings to be a tight fit in the
barrel but this fit must not be so tight as to close
down the outer race of the bearing and thus
overload the balls.
8. Refitting Ball Bearings
Note that the two ends of the spindle are not
identical. The end with the shorter plain portion
between the thread and the shoulder must be
fitted to the brake drum side of the wheel.
To refit the bearings in the hub two hollow
drifts are required, as shown in Fig. 2. One
bearing is first fitted to one end of the spindle by
means of the hollow drift ; the spindle and
bearing are then entered into one end of the hub
barrel which is then supported on one of the
hollow drifts. The other bearing is then threaded
over the upper end of the spindle and driven
home by means of the second hollow drift either
under a press or by means of a hammer which
will thus drive both bearings into position
simultaneously.
DRIFT FOR REFITTING BEARINGS
In order to make quite sure that there is
clearance between the inner faces of the outer
bearings and the bottom of the recesses fit the
distance washers against the inner races of the
bearings and either fit the assembly of brake
cover plate, speedometer gearbox, etc., or make
up this distance with tubular distance pieces. Fit
and tighten the spindle nuts. Tightening the nuts
should not have effect the ease with which the
spindle can be turned. If tightening the nuts
