that end. Remove this bearing first, then enter
the loose section of the spindle into the spacer
and drive out the remaining bearing by means of
a hammer and
hexagon-headed end of the spindle.
8. Hub Bearings
These are deep-groove single-row journal
ball bearings. The sprocket/brake drum bearing
is a Skefko RLS7, 7/8 in. i/d, by 2 in. o/d, by
9/16 in. wide. Equivalent bearings of other
makes are Hoffmann LS9, Ransome & Marles
LJ. 7/8 in., and Fischer LS9. The two bearings in
the hub barrel are Skefko RLS5, 5/8 in. i/d, by
1.9/16 in. o/d, by 7/16 in. wide. Equivalent
bearings of other makes are Hoffman LS7,
Ransome & Marles LJ 5/8 in., and Fischer LS7.
9. Removal of Hub Driving Pins
To remove the six driving pins from the
aluminium fullwidth hub, first remove the hub
cap after unscrewing the three screws attaching
it to the hub. Unscrew the six Simmonds nuts
and drive out the pins.
10. Refitting Ball Bearings
To refit the sprocket/brake drum bearing, use
a hollow drift as shown in Fig. 4. The bearing is
first fitted to the fixed section of the spindle ; the
spindle and bearing are then entered into the
sprocket/brake drum
preferably under a press or using light hammer
blows.
The two bearings in the hub barrel are pressed
in, using the drift part of E.4823. First assemble
the bearing into the circlip grooved end of the
barrel and fit the circlip. Replace the bearing
spacer, the slot in the spacer can be at either end
of the hubs, and assemble the second bearing,
supporting the hub on the inner race of the other
bearing. If the drift part of E.4823 is not available
it is essential that the last bearing is assembled by

drift applied to
and driven home,
applying pressure to both inner and outer races
simultaneously to avoid pre-loading the two
hub barrel bearings.

11. Reassembly of Brake Shoes, Pivot Pin
and Operating Cam into Cover Plate
No difficulty should be experienced in
carrying out these operations. Make sure that
the pivot pin is really tight in the cover plate
and put a smear of grease in the grooves of the
pivot pin and on the operating face of the cam ;
also on to the cylindrical bearing surface of the
operating cam if this has been removed. Fit the
operating lever and trunnion, 23371, on its
splines in a position to suit the extent of wear
on the linings and secure with the nut. The
range of adjustment can be extended by
moving the lever on to a different spline.
12. Centering Cam Housing
Note that the bolt holes in the cam housing,
26347, are slotted, thus enabling the brake shoe
assembly to be centered in the drum. It is not
intended that on rear brakes the cam housing
should be left free to float but the shoes should
be centred by leaving the screws, 26309 and
35140, just short of dead tight. The brake cover
plate assembly with the shoes should then be
fitted over the spindle into the brake drum and
the brake applied as hard as possible by means
of the operating lever. This will centre the
shoes in the drum. The screws should then be
tightened dead tight and secured with the
locknuts. If the shoes are not correctly centered
the brake will be either ineffective or too fierce,
depending on whether the trailing or leading
shoe first makes contact with the drum. With
the brake assembly correctly centered and the
screws securing the cam housing correctly
tightened wear on both linings should be
approximately equal.
13. Final Reassembly of Hub Before
Replacing Wheel
Before replacing the felt washers which
form the grease seals, pack all bearings with
grease. Recommended greases are Castrolease
LM, Mobilgrease MP, Esso Multipurpose
Grease H, Energrease L2, Shell Retinax A or
Marfak Multipurpose 2. These are all medium
heavy lime soap or aluminium soap greases.
The use of H.M.P. greases which have a soda
soap base is not recommended as these tend to
be slightly corrosive if any damp finds it way
into the hubs.
Make sure that the inside of the brake drum
is quite free from oil or grease, damp, etc.

brake cover plate assembly, speedometer drive
