MG TD TF 1500 - cracked transmission bell housing

Still taking apart 1954 mgtf in restoration project. I found that the transmission bell housing is cracked. Should I try to get it welded? If not, where would I find a replacement?

(I drained the trans fluid. The car sat for 28 years. The oil came out in clumps. Yuck.)

Ed,
How big or long is the crack,,, where is it located on the bell housing? Can you post a picture some where??

Ed,

Others on this bbs might have better expertise in this area, but I wouldn't want to re-use the bell housing. The engine and transmission are only supported at the front of the engine and the rear of the transmission. The bell housing sees a significant load.

I would watch ebay or check other used part sources for a bell housing and maybe a full transmission if you find other broken parts inside.

Good luck! Let us know what you find.

Depends on where the crack is, and the extent of it. A good welder can do wonders on aluminum. George

Get it TIG welded.

I don't think the location of the crack matters. It is aluminum and can be made good as new.

Call Brian at OConner Classics and see if they have a bell housing - it is easy to install on your gearbox.

Good luck

Welding a crack on aluminium can be tricky, but a good job will be as good as new.

Just be sure to get somone who has experience with welding aluminium. A sweat weld will probably work, but again, it takes expertise.

If you do decide to buy another bell housing, remember there are three different ones - one for the TC, one for the 7¼" TD, and a third 8" for the late TD/TF.

"remember there are three different ones - one for the TC, one for the 7¼" TD, and a third 8" for the late TD/TF."

Any part #s or indentifing marks? I need to go figure out what it is that I have.

I have a couple of spare bell-housings. The TF one is here at my house. The other is not. Here is what I can offer:

OEM (MOWOG) part numbers:

TC - SA2414
TD 7¼" - SA2239/3
late TD/TF 8" - SA2239/4 casting nbr 168022

When my engine decided to destroy itself two years ago, I found the bell housing had a crack about 2/3 of the way back.

My local welding shop is good with aluminum and had no problems welding it. If they can get to both sides, the weld will fill just fine. I smoothed the welds and it looks as good as new.

So far, no problems.

If you do take Gordon up on his offer. I still would not throw it out.
