CAUTIO N
Do not hit the circular driving lugs on
the shaft head. This may cause the lugs
to shatter and splinter. Do not use
chisels or wedges to loosen the shaft
or dowels. This will damage the hub,
shaft and oil seal.
b.
Remove the eight axle shaft stud nuts (27, fig. 12-2), washers, and tapered dowels (25). To
loosen the dowels, hold a 1‘A-in. diameter brass drift against the center of the axle shaft head, inside
the circular driving lugs. Strike the drift a sharp blow with a 5-6 lb hammer. A 1%-in. diameter brass
drift is excellent and safe.

Break the carrier loose from housing with a rawhide mallet.

the carrier free. A small pinch bar may be used to straighten carrier in the housing bore. However, the
