I have a cast-iron short tail A-833 with an input bearing retainer measuring a little over 5.1 inches, which would make it an OD, I believe. I was under the impression that all OD A-833s were aluminum. Is there a way I can tell for sure?

The next question, is it possible and how hard is it to swap a '70 and later long tail shaft onto/into it? Anyone done this before?

Rabid,

Here's a good article:

Hope there's some info you can use.

P.G.

the early ODs were cast not alum , what you have is much harder to find , , a short tailshaft A body cast iron od 833, you will need the long main shaft & long tailhousing to switch it to a E body application , I have both pieces if you need them

Thank you for the link, I have checked it out.

Chryco, I would be very interested in the tail and main parts. I'm sending you an IM right now!

Is swapping tailshafts something I'll need a press to do? I have the tranny partially disassembled right now, and the tailshaft seems to be caught on something, but I don't see a clip or anything.

no you do not need a press ,the OD is difficult to assemble & disassemble, you need to pull out the front input shaftas far as possible , rotate the tailhousing 180* pry the counter shaft back with a small screwdriver & remove the key then tap the shaft forward to drive out the frost plug in the front of the case & slide a dummy shaft into the counter shaft to retain all the rolller brgs & drop the counter shaftinto the bottom of the tranny case [I can get you an exact measurement for the needed dummy shaft, it can be made from heater hose or conduit ] & put the front syncro forward to remove the tailshaft & housing as 1 unit , then on the top of the rear housing there is a window where you need to expand a snap ring to remove the rear brg & main shaft, from there you need to remove snap rings & swap all the gears syncros & brg to the longer main shaft a reassemble the tranny

Alright!� I got my tailshaft!!� �

� I have to thank Neil (Chryco Psycho), he is a top rate guy, and the parts were all beautiful!� �

Can't wait to get this transmission put all back together.� It'll will give me an incredibly steep first gear (3.09, similar to a GM 700r4's 3.06 first gear), and a 149 MPH @ 5500 RPM with my current 3.91 rear-end.� With 3.23s the top speed goes up to 180 MPH @ 5500 RPM.....�

Anywho, I got the tranny disassembled, and while trying to remove the countershaft, I used a section of rubber hose to hold the roller bearings from coming out, then I screwed something up (the rubber hose was too small...� DOH!), and all the roller bearings fell out.� � �

� I suppose I learned something by doing this....�

Is it this hard to fix?� How do I go about re-installing all those eight billion little roller bearings?� �

72 rollers to be exact
you need a dummy shaft the correct length & diameter to go inside then use a thick grease a pack them carefully , into the counter gear use 18 rollers then the spacer ring 18 more rollers & the second spacer ring from each end , put the best thrust washer at the rear or replace the bad one

I was swapping tailshafts and tailshaft housings, putting the E-body long tail shaft into an early cast-iron A-body OD four speed case, and ran into a problem.

The original A-body mainshaft had a bearing at the end of it, and the longer B/E body tailshaft end is bigger and will not let me put the A-body's bearing on it.� Please see the picture below.

A.� The long tailshaft, out of an E or B body, with all the swapped on gears and such.
B.� The bearing from the A-body tailshaft, which fits shaft C, but not shaft A.
C.� The short tail, from a A-body OD tranny.

I sent an email over to the guys at Passon performance, and they're stumped too.

Scott,
We have built literally hundreds of these and I have NEVER seen something
like this before.� I need a picture of the A Body shaft in its entirety.�
Also, the gears that are on the long shaft, are they from the A Body shaft?�
Please take a picture of the inside of the input shaft on the A Body
transmission.� I am starting to think that someone retrofitted this bearing
in because these transmissions never used a raced type bearing on the tip of
the shaft like is shown in the picture.� You can call me as well if you see
fit.
Thanks,
Jamie

I'm going to call Jamie back, I just want to throw this up here to see what Chryco and the rest of everyone thought of this.

I have not seen that before either , usuall there are rollersa inside the drive pinion , not a roller brg , possibly the front of the mainshaft was damaged so it was machined down & a brg was fitted
