HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

I'm not sure what to think about the 928 TT's
I recently went to the Porsche graveyard and measured what I thought to be a 928 Manual TT. However there were shorter TT's and some that had extention tips that connected via a shaft adapter similat to the 944 TT to transaxle sleeves...
anyways here's what I found on a couple of the TT's (I think these were 5 speed TT's) I may stand corrected....

Flange?
Bolt pattern?

The 928 uses a coupler @ the flywheel - can be eliminated when installing GM V8.
I came up with a 944 to 928 TT dimensional difference of 3.76".

Hmmm, sounds about right...(using the SMS method) Razz

After seeing all the 944 Flange dims off everywhere I didn't bother.....Figured I would use the SMS system when I make an adapter Razz
It was dark inside the building and mosquitos galore, had to bail quickly affraid

I did see that there was a short and long tube as well, maybe one was for Auto and the other for Manual, but not 100% sure either.

Hello,

This is my first time posting... I think there are at least two different lengths of torque tubes in the 928 manual cars. Perhaps the slip collar offers some minor tolerance for BH adapter length?

If we could just get the TT face dimensions... Not sure what SMS is. Must be something similar to my portable Lufkin dimensioning system ($6 at the HomeDepot) drunken

Here is a picture I found in a TT rebuild post that adds some pieces to the puzzle

Here is another bit of information related to the original 928 manual configurations.. Single and Dual disk

Yep...
Saw those. Flange bolt pattern is what we still need.

S.M.S.:

Ok back on this subject. The first pic with the longer 1 piece shaft is the AUTOMATIC Torque Tube and the 5-speed has a coupler designed so clutch changes are easier....I wish the 944 had a 2-piece with coupler but that's another story.... Anyways that coupler has a maximun rotating dia. of 2.75" (Eric) and another measurement of 2.73" by Constantine. Measure twice cut once right? By the way, if you haven't heard, Constantine, the TT rebuild guru is building all-new 944 Torque Tube Shafts from stronger steel and even Zinc Plating them. So if you have a Renegade kit, you might want to contact him Razz

Anyways, I don't build anything on SMS so I will get the 928 Flange dims from him and if Eric can confirm, we're on our way.

Constantine rebuilt a 944 shaft for me, his work is first class.
