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.
REMOVAL OF BRAKE SHOE ASSEMBLY
Fig. 2
5. Removal of Hub Spindle and Bearings
To remove the hub spindle and bearings
having already removed the brake cover plate
assemblies, lift out the felt washers, Part No.
21466, and distance washers, Part No. 30538.
Now hit one end of the wheel 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
the other way, when it will bring out the
remaining bearing.
6. Hub Bearings
These are deep groove single row journal ball
bearings 5/8in. i/d by 1.9/16in. o/d by 7/16in.
wide. The Skefko Part No. is RLS5. Equivalent
bearings of other makes are Hoffmann LS7,
Ransome and Marles LJ5/8in., Fischer LS7.
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
pieces, 30538, which in turn are held up by the
cover plate nuts 31347. 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.
The following are the manufacturing tolerances
which control the fit of the bearings. The figures
for the bearings themselves are for SKF bearings
but other manufacturers' tolerances are similar.
Bearing o/d 1.5622/1.5617 in.
Housing bore 1.5620/1.5616 in.
Bearing bore 0.6252/0.6247 in.
Shaft diameter 0.6252/0.6248 in.
8. Refitting Ball Bearings
To refit the bearings in the hub two hollow
drifts are required, as shown in Fig. 3. 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. In order to make quite sure that
there is clearance between the inner faces of the
outer bearing races and the bottom of the
recesses, fit the distance washer 30538, and the
cover plate nuts, 31347, with either the cover
plates themselves or additional packing washers
behind the nuts. Tightening the nut should not
have any effect on the ease with which the
spindle can be turned. If tightening the nuts
makes the spindle hard to turn this may be taken
as proof that the bearings are bottoming in the
recesses in the hub barrel before they are solid
against the shoulders on the spindle. In this cage
the bearing should be removed and a thin
packing shim fitted between the inner race and
the shoulder on the spindle.
