(See Fig. 7).

Take off both spindle nuts, and lift out the brake plate and shoes from the brake drum. By using two spanners working against each other, loosen the lock nut on the left-hand end of the spindle and take this nut and the bearing adjustment nut off the spindle. Take off the dust cap. Using a punch made of brass, copper, or aluminium-alloy drive the spindle through the hub towards the brake drum. In no circumstances must the spindle be driven out from the brake drum side towards the left. The centre of the roller bearing on the right-hand side will come out with the spindle. The dust cap from the left-hand side of the hub is easily prised out of place and the centre part of the bearing can be taken out Both bearing cups in the hub can now be repacked with grease.

If the roller bearings have to be renewed due to wear or damage, the old outer bearing rings have to be driven out of the hub in which they are a fairly tight fit. When removing them it is almost impossible to avoid scrapping the grease retaining washers which are inserted between the outer bearing rings and the internal shoulders in the barrel of the hub. If a punch is to hand which will just fit through the barrel of the hub the retainer on one side may be saved but as one ring and one washer must be taken out before such a punch could be used it is usual simply to drive both rings out of place with an ordinary bar about lir-in. diameter and 10-in. long, replacing both grease retainers with new ones on assembly.
