Hey everyone,
I build trans and rear ends used in all types of
racing and here's the deal on the hose clamp on the
tail housing: the clamp is there in case you need
change the seal, for instance, at the track. the
choice of seals varies depending on availablity. The
seal that comes with the trans has no lip and is
seated in the end of the tailshaft housing. If you
must replace it you may only be able to find a seal
that has a lip on it. the lip extends beyond and cover
over the end of the housing to put it at the right
depth. To help keep it in place you use the hose clamp
to hold half inch by half inch sheet metal "clips" or
straps that you bend over the lip of the seal to
retain it in place.
As far as the roller bearings in the tail, use them if
you need to. They do require that you use a hardened
slip yoke on the driveshaft. These are expensive,
however. the standard slip yoke is used with bushing
tailshaft housings and must have a zerk for grease.
The bushed tailhousings survive very well at high rpm
(on the order of 9000) as long as you routinely grease
them. The rollers rely on splash oiling from the
grease in the tranny and the grease migrates there via
the mainshaft(output shaft).
Hope this helps.
Tom
