The following relates to the MGB, but you really need to confirm the detail
with a Midget Workshop Manual. Note how the outer rings are pressed into
the hub before you drift them out. Basically the taper in the rings must be
facing out on both sides or you will not be able to fit the races
subsequently. The oil seal must be fitted afterwards, with the groove
filled with grease and facing in to the hub. There is an oil seal collar
that goes onto the stub-axle first. Then the inner ring of the inner
bearing, then the inner race. Then the spacer tube, spacer shims, outer
race, and inner ring of outer bearing. Finally the washer and nut. It is
important that the grease is pressed or injected into the races from one
side only, until it oozes out of the other side. If you try and
short-circuit things by pressing a bit in from each side you will end up
with air in the middle and insufficient grease. Don't pack the remainder of
the space inside the hub with grease. You need to check the end-float or
free play, which is .002" to .004" on the MGB. The book says to use a dial
gauge, but if you don't have this arm yourself with up to 4 .003 shims, and
one each of .005 and .010. Then you can juggle shims altering the thickness
1 thou at a time until you find one set that give just perceptible play and
another 1 thou thinner that gives none. Fit the thinner set plus an
additional .003. This is best done *before* you pack the races with grease.
Finally tighten the nut to 40 ft lb, then to the next split-pin hole.
But as I say you really need to confirm the detail with a Midget manual.
