59 pin and castellated nut from the end of the swivel axle spindle. Apply a drag

to hub and withdraw hub and brake drum complete. On cars bearing chassis
number R 3061 and onwards the front hubs can be readily drawn off by
hand, therefore no thread is provided for a drag.

TO DISMANTLE ( Before R 3061 )
SECTION Dismantle hub from brake drum by removing the locking nuts from the
60 end of the wheel attaching studs. These studs are burred over and care

should be taken in removing the nuts so as not to damage the threads. If
the nut is slackened off a little to turn back the burr and then tightened
up again, the burr can be filed off.

Remove the spring retaining ring, washer and grease retaining washer from
large bearing housing.

ball races are fitted correctly. The side stamped ‘THRUST ‘ on the outer
race MUST be against the shoulder in the hub. This applies to both races.

ends after the nuts have been thoroughly tightened.
