TECH: Ultimate T-5 Article

You asked me this question and I can't give you an answer.Try asking Krylon32 - a member here.

 

Yes.

Take it apart, put it back together, with the different shaft. The gears go on it.

Shim for zero-play.

 

Got it, I have to pull it back out again to swap to the mechanical housing from the electric anyhow...... I was just on the McMaster website looking.
Thanks.

 

I have a 67 Mustang dual pattern 200 I6 and have some crazy notion that I would like to use a 9" clutch setup instead of an 8.5. Is there a bell housing that I can use to put a T5 behind my engine with a 9"clutch. Also is the early Econoline bellhousing the only bellhousing that will mate up with a s10 T5 Chevy bolt pattern. This is going under a 61 Falcon wagon so it would all have to fit as well.

I can unbolt stuff but can't remember where it goes back...

 

Can't help you there.Start a new thread and ask that question

 

For what it's worth, I used Ford bellhousing #D20A 6394 AA which is not an Econoline bell, plus an adapter plate to mate with a Ford pattern T5. I'm unaware that there are any Ford bells with Chevy patterns, but I do know that late S10 transmissions (World Class electric speedometer units) had Ford bolt patterns. In any event you'll need an adapter to the older Ford (T10 and Toploader style) bells, not just for the bolt pattern, but because the T5 input shafts are longer.

 

Chevy astro van used a GM bell housing, with the Ford t5 gearbox bolt pattern. Odd duck to say the least.

 

Is the 200 L6 the same bell bolt pattern as the 289, and 302? I have a bell from mid 80s mustang that had a t5.

 

"Mate up" with an adapter plate.

 

Not so odd. All Chevys (and Pontiacs, etc.) with WC T5s have the Ford bolt pattern.

 

But, the camaro and firebirds were tilted to the side, and the astro van allowed the shifter to be upright.

 

And the Astrovan T5 had a unique shift adapter that moved the shifter towards the driver side.

 

Only the very late ones. The early ones do not. They have their own pair of patterns.

 

The early Econoline bell has the Ford "narrow toploader" pattern on it.

There is a common adapter that takes that to the GM/Muncie/Saginaw pattern. That adapter is 5/8" thick.

The S10 T5 has an input shaft that is about 5/8" too long. Fold in that adapter, and this becomes a bolt-on.

In hindsight, doing this conversion, I would have just turned down the T5 collar to take the Falcon throwout bearing.

That's what I am did on Phase II. Seems to work a little better.

These bellhousings are not hard to find, nor are the adapters.

The trouble with going with something other than an S10 T5 is the gearset. Almost all other T5's have dramatically incorrect gear ratios for the engine, unless you also changed the rear end ratio.

 

The problem with the 9" clutch bellhousings is the depth. They are all much deeper than the 8-1/2" clutch bellhousings.

This leaves no room for an adapter, to get the S10 T5 on to them.

If you use a Mercedes pressure plate, there is no advantage to the 9" clutch.

The Mercedes pressure plate should be good for 250hp, and a similar amount of torque.

 

That's some good info there...

 

"In hindsight, doing this conversion, I would have just turned down the T5 collar to take the Falcon throwout bearing.

I remember you saying somewhere on here that you built up teeth on the fork.
What do you mean by turn down the collar?

 

This is the input collar, it is where the throwout bearing rides:



In the lower picture, the dark grey area needs to be turned down on a lathe, to fit the stock Falcon bearing.

 

I have a '88 WC T-5 from a Camaro (#13-52-176) with a Chevy bolt pattern.

 

GM went to the Ford bellhousing pattern 1993-end, on all T5's.

I suspect that this was a vendor decision, as GM's use of the T5 was declining, and they wanted to trim the variants down to save money.

 

Using the fork from the econoline bellhousing ?

 

There appears to be only one 8-1/2" clutch fork. I used the one from my original bell, in the Econoline bell.

Now, in Phase II, I am back to the stock bell, a turned down collar, and an unmodified fork.

I will post pictures in the Doing Falcons Right thread, when I make some progress, besides machine shop work (as this is a T5 thread, and I'm not putting in a T5).

I ripped up my shoulder, which has substantially slowed my work.

 

Sorry, my mistake. Seems the bolt pattern changed around 1993. I thought it coincided with the switch to WC in 1987-88.

What has happened to Flat Ernies T5 tech on page one? Is it my computer not reading it , as all I get are Font codes from half way down??

 

It's not you. It's messed up.

 

Darn , this info is way too valuable to get messed up, Flat Ernies put too much effort into this to loose it.

 

Another casualty of Ryan's "can't leave well enough alone" syndrome.

 

It wouldn't be that hard to fix by somebody that can edit the message.

 

OK - I fixed some of it and even made a few minor updates. I will have to get to the pictures later as I don't have them on this computer. All of my T5 info is on another computer packed up and in storage. The original is also on the flathead techno site in pdf format:
