John (and list),
The carriers will not necessarily interchange. I guess I'm still not real
clear on what your trying to do. At any rate, the bearing sizes went
through four or five iterations and as such some outer casings as well as
carriers use different bearing sizes as well as different diameter shims
for setting pre-loads. It may or may not be possible to use one carrier in
a different casing I would have to see (or have part numbers) of the parts
in question. It is possible to mix and match some bearing/carrier/case
combs, but not all. The same applies to innards. The main problem you'll
encounter is that there are at least two 3.27 carrier types that I know of.
With one type that I have seen/used the ring gear requires special thin
head bolts with NO lock washers and uses Loc-Tite to secure the bolts.
This carrier can ONLY be used with the 3.27 gears. No other (stock) ratio
will fit. It is machined differently and the offset of the gears requires
this. If that's what you have, you CAN NOT use the gear set out of the
other unit with this carrier and vice versa. Like I mentioned before, the
internals are NO STRONGER than the Spitfire parts, so if your swapping for
what you think are stronger internal parts, your not going to achieve this.
If your doing this using parts from both units to make one good one, you
may not be able to do so because of the mismatch of the carriers due to
design constraints. If I knew EXACTLY what you were trying to accomplish,
exactly which parts will go in which casing etc., I may be better able to
guide you in the right direction.
I have copied these responses to the list also because others may be
interested in this information (having been there done that). I hope this
is alright -
