Been studying Carl Munroe's 727 book and working on gathering tools in preparation for pulling and overhauling my 727 this winter.

A few questions for the experienced:

1. What's an alum 727 minus converter weigh on average?

2. My bushing driver set is pretty basic (and undersized) and thinking about buying a little better one. Will bushing drivers up to 1-1/4 inch pretty much handle what I will encounter?

3. Most of my snap ring pliers are pretty small so looking for a heavy duty one for the bigger snap rings like the one securing the tail housing and the ones on the output shaft. Is a HD 8" pair of snap ring pliers large enough - like this?

Or do I need bigger yet?

4. Pulling the pump out - looks like it would be pretty easy to thread a couple pieces of all-thread into the two threaded holes, lay a piece of angle iron over the mouth of the bell housing with two holes drilled for the all-thread to penetrate, install washers and nuts and just wrench it out. I'm surprised I haven't seen anyone suggest that - any reason it wouldn't work?

Thanks for your help.
 
I use two bolts and a dust cap remover. Make sure you have both internal and external snap ring pliers. Learn to inprovise fancy special tools are not required. Most of my trans tools are home made.
The tail shaft snap ring can be removed with 2 std screwdrivers and a block of wood. Save your money for a good inch pound torque wrench.
 
You can make a front clutch spring compressor with 1/2"all-thread rod, 4" of small angle iron, and 2 heavy nuts.

Will a hydraulic press work?

Thanks for the replies. I'm a fairly good improviser but I would like to use a good set of bushing drivers as it's easy to bugger up the edge a little using punches or home-shift items to set them in place and then have to ream or file them a little.
 
The only bushings I ever have replaced in a normal build are the pump and the tail shaft. I made drivers for both. Yes on your other items.

Check input shaft endplay and tighten down front band so guts don't fallout if you do it on a bench. In other post someone said to have trans standing vertical in a 55 gallon drum, while disassembling and reassembling, good idea. Unless you put a window in side of drum I'd remove the pan and valve body first.
 
Thanks Fran - l picked up those hints out of Carl's book. Apparently he knows his stuff. I was thinking of hanging the trans vertical from my transmission hoist with a couple pieces of angle iron. I don't guess there are any check balls or anything that might get loose in this position before I notice them?
 
All check balls are internal to the valve body. A couple of 90 degree brackets off an engine stand work great.

You might want to remove the tail shaft housing before mounting it vertical. Can't think of a reason not to. If there is someone will post it.
 
I like the horizontal position that way if you drop something it falls onto the top of the case instead of into everything that has been installed.
 
I've always done T.F.s on their right side on the bench. Built them professionally in dealerships for 7 years and at home for the last 38 years-no problem. If you have a friend with a metal lathe, bushing drivers are real easy to make. Merry Christmas!

Help, or not...
My usual is to strip out the pan/shift body first. Shift body can be pretty much pulled, and put aside, to be worked later. Then the tail shaft housing...leave the shaft in place.
Then, trans goes onto a vertical stand, sitting high enough to clear the output (tail) shaft. On tear-down/build, that output shaft is just about the last/first part going into the main housing.
You'll figure real quick it's much easier to un-stack/re-stack the parts in the main case.
 
Totally agree with Miller. Have only done my own more than once, but for me horizontal always let stuff droop from gravity & harder to line up.
 
I also improvised every special tool I needed. Not a real big deal.
 
Yup...not that hard. Just a dab of common sense, while your going through it, keeping track of parts.
Key things are sizing, correct clearances, and clean parts. Also kinda satisfying doing it yourself.
