Transmissions Hate me,,Won't Come Apart

Ok,,been down this road with the OD trans,,but that thing was rusted and had sat a zillion years.. This ones just fine .. So undid the 5 bolts that hold the rear hosuing on,, and it comes out about a 1/2 inch then stops

The speedo line is out so figure thats not it..What am I missing here ??

My Packard Transmission book does'nt ( is'nt new enough ) cover these transmissions ,,and can't find anyy real info on em..

Any ideas ?? Don't wanna just try and force it and break something

 

There is probably a snap ring on the rear bearing at the front of the tailshaft housing. I've had the same thing on saginaws.

Look for a space around the bottom of the flange that aligns the tailshaft with the main housing.Look for the ends in the space.

Good Luck.

Since you seem to get yourself involved in O.D.s quite frequently, you need the Borg Warner manuals. (As far as I know, all the planetary O.D.s were B-W or very similar to ). Try oldcarmanuals.com. I'm sure they have a downloadable version.

 

In book I have, snap ring seems harmless...it just lays on back of case with tail casting securing it like '39 Ford. You have the U-Joint flange unbolted I think...book says speedo gear must come out first, cannot see why in picture or if it is retained by anything other than that flange. If your driven gear is still on there, maybe it is hung on the speedo drive gear.

 

Ok I looked inside the trans and sure enough there seems to be a snap ring as it seem the tail shaft is also the bearing carrier

now there as no holes on teh ring or any real way to get to it,,,,taking it out should be interesting

as in teh Picture this is NON OD,,looked on the Packard site and could'nt find anything on these 50's ones.

Maybe I need to write a book on these when im done

 

Got kids at home? Just leave it out on the coffee table and tell them NOT to take the housing off in one piece.

I don't know if this will help, but here's an exploded view.

 

Sorry, now that I look at it, Its not the same transmission.

 

the manual I have for 53 packards says to remove the top cover and drive out the countershaft first, then the cluster gear will drop down and let you remove the main drive gear (input shaft) Then unbolt the tailhousing and remove the mainshaft/tailhousing, and then you open the snap ring to pull the shaft out of the housing. pretty common procedure for taking a manual trans apart.

 

Questions Can I get a scan of that if there is a diagram ,,

How ever I do it tht snap ring with no holes to compress it..

Is there a special tool or way to get that ring off ?

 

Did you take the mainshaft/tailhousing assembly of of the case?

If so, take a picture of the snap ring, and the hole it sits in, and any notch or other area that might make it easier to remove.

It's a paragraph, not a diagram. The later trans is not illustrated, only the early ones with the very short tailhousing.

 

That makes a lot of sense now, being that this trans doesn't look to have a bearing retainer plate like a Muncie, T-10, etc, assuming the bearing registers in the tail housing and not in the case like a Ford top loader. I suppose with the whole assembly out, the snap ring would be a lot more accessible.

 

ok that was easy came right out the ends of teh snap ring are where the arrows are

and if there is a special tool to get this kinda ring out,,I need the name of it,,,lol

The ends come to angled points so im guessing that you's put something in there that gets under it and expands ??

 

That snap ring; it has a slant on each end of the ring. That sharp angled point is what you need to pry up with a good quality screwdriver that has sharp edges on all sdes of the tip.

Go slowly trying to just pry it out just enough to slip a very thin screwdriver under the ring to block the groove. Then if you do have it started, you now keep prying that angled tip to get more thin tools under the ring. At some point, you need to pry the angled part out away from the gear.

 

Tried the damn ring keeps wanting to spin,,,,grrrrrrrr

 

I always start out with one flat head screw driver, a heavy duty angled pick, and some heavy duty needle nose plyers.
Place one screw driver against one side to stop it from spinning. Use the angled pick to bring the other end out from under recess. As the ring end starts to come out turn the pick up and use the leverage to pry it out more. Once you have a good bit out, and the pick stopping it from snapping back in grab your needle nose plyers to coax it all the way out.

 

Here's what my borg unit has: On the top of the tail shaft housing should be what looks like a small rectangular dustcover. Take it off. Inside is a snap ring with two tangs facing up. Spread them while pulling the housings apart.

 

The issue is as you can see in the pix is that gear is so close to the tail it makes the ring really hard to get to.. I tried taking the gears off the shaft,,but after the syncro,,the rest kinda don't wanna move,,gonna try and make some kinda tool today and see if that works..

Thanks all for the info
