engine and drivetrain Auto trans question...

[TobyB]

well, actually, bellhousing...

What's the 'thickness' of an auto bellhousing?

As in, if you unbolted it from the engine and transmission,

flopped it engine- face- down on a flat surface, and then measured from

the flat surface up to the transmission- mounting surface?

Thanks!

TELL US WHY your asking - and maybe

someone will take the time to answer - if it's wurthy

[gracer]

I'm betting that he wants to use one to adapt a quaife five speed. Am I there Toby? G

[TobyB]

Hell, no, I shan't explain, for it is

YOU are not WORTHY, my good

NON 2002 owning POSTINI!!!

hee hee...

CD, I do love you, but why not say that you just don't know?

And anyway, 3m stuff is every bit as good as Wurth, and a

darn sight cheaper... and easier to find...

Here's a picture or 2 to gross you out.

(Gordon, you're close, but a Quaife would eat up next season's

entire shrimp budget, if you know what I mean?)

ps, if anyone knows the actual dimension, I'd be grateful! The victim is

far too lengthy to be easily adapted...

[peteinjp]

Comeon man- spill the beans!

Might be worth checking on one of the s14 forums as to the size of the 265 bellhousing.

Why do my door seals fall off when I use the 3m stuff and stay stuck when I use the Wurth stuff....Hmmmmmm?

Toby,

I don't actually know your answer but I do know its been discussed here before. I think the guys were discussing how Jensen Healys used the same Getrag CR box with a different bellhousing so the post had all the dimensions up there...

I know (or I think) ToddK was involved in the post, possibly try searching his user name and "Jensen"???

I'm at work and have limited FAQ'ing abilities here with internet filtering and all...

What gearbox is the donar?

[PSloan]

I don't think it's a Jensen box. Maybe a japanese something?

[TobyB]

Yup, it's in fact Japanese...

Alp would be able to guess, as he has one (or 6) of 'em...

It's a Nissan from the late '60's. The ratios

(with a 4.44 diff) are pretty darned good for a 22" rear tire

and a motor that doesn't wind past 7500. And when I do,

the later Nissan boxes have the same bellhousing, so 'gear' changes

will become 'gearBOX changes.

AND it'll work with a 1- piece, dry driveshaft. It's so good a fit

you'd think it was made for it. Well, except for the bellhousing...

So I need a bellhousing for it, with a short (145mm) depth.

When you mill the back off a standard box, you kind of run out

of aluminum about 160mm... and I was trying to find out if

it was worth chasing down the auto housing or just setting to

work with the tig.

The auto cars do show up in the cheapo junkyard from time

to time, but (as it alwasy happens) there haven't been any there for a

while. I may have to range farter...

Winston, the Jensen discussion got close to the answer, but never

made it there... good memory, though!

[gracer]

Toby, I used a stock belhousing that was machined down with an adapter plate welded to it for the correct dimension. G

[TobyB]

Right on, Gordon-

that's this weekend's project!

Well, maybe next weekend- I need a boring head

to mate the adapter plate to the donor transmission...

You do know, though, that I'll be slower after I do this?
