Clean the hub and races well with paraffin or white spirit. Then drive the races away from each other. The inner and outer races may be of different sizes. If so, begin with the smaller one.Use a socket as a ‘drift’ (pusher). Choose one which fits through the larger race to rest against the smaller race.NBR auto oil seals sophisticated technology.
Lengthen the socket with an extension piece and tap this gently with a heavy hammer to expel the race. Use a bigger socket to force the other race out in the opposite direction.Lightly grease the stub axle, including the threaded end and the shoulder at the base. Keep grease off brake parts.

Insert the inner race of an outer roller bearing.Fit the thrust washer with its chamfered side towards the bearing. auto oil seals.Screw on the hub nut, then adjust the hub. Position a castellated nut so that it lines up the the split-pin hole – by easing the nut, back, not forward – or fit the nut cover if there is one.Insert a new split-pin, head uppermost, and open the legs. Trim the legs so that they will not prevent the dust cover being fitted. Reassemble the brakes.NBR auto oil seals sophisticated technology.
If the races are the same size, remove the first one with a flat-faced punch and heavy hammer, tapping alternate sides and working evenly around the race so as not to tilt and jam it. Be careful not to scratch the inside of the hub.When the first race has been removed, free the second race, using a socket as a drift.NBR auto oil seals sophisticated technology.
