Hi, Sam -
You are rebuilding a BJ8 gearbox, yes? BJ8 gearboxes do not use the AEC3183
spring bearing plate. That is for BJ7 'boxes.
The stackup of shims, etc. is intended to make sure that there is a positive
pressure on the gearbox front main bearing outer race when the bellhousing is
clamped up, to minimize the possibility of the outer race turning. The goal
is to have the thickness of the bearing and shims to be just a bit greater
than the depth of the bearing recess. I found it a bit hard to measure the
recess depth (the front bearing broke up and gouged the recess in the
bellhousing), so I used the two shims that were already there and cut another
one out of a paint thinner can to make sure that the new bearing was clamped
up.

Subject: Transmission rebuild
In reassembling the bell housing to the transmission, I discovered I
didn't have a spring bearing plate(AEC3183) as called for in the
mechanical service parts list. This round plate fits in a cavity in the
bell housing and between the drive gear bearing. There is also two
bearing shims called for( A/R) which I have. I have not been able to
find a source for the spring bearing plate and was wondering if there is
a source, and if it is really required. With the packing shims being
called for, it looks like you are trying to obtain a certain clearance.
The amount of the drive gear bearing that protrudes out of the
transmission beyond the circlip and the thickness of the shims, looks
like it will fill the cavity without the bearing plate. Could someone
shed some light on this and if it is a certain clearance that you are
trying to obtain, what is it and how do you measure it.
Thanks,
Sam Austin
