Transmission Mounting with or without spacer

[Rockonp04]

I am converting my clutch from a hydraulic throwout bearing to the stock orientation. We have already milled the pilot bearing shaft down to fit the pilot bearing inner diameter. We have the Jose spacer plate. Do I need to use the Jose spacer plate? Do I need to do anything else to the transmission before mating it to the engine? I plan on using the spacer plate and then mounting it up. Does anyone foresee anything wrong with this?

Does "... the Jose spacer plate" refer to a pilot bearing input shaft extension adapter that allows the use of a T-5 transmission with a 7.18" input shaft with a M-II 2.8 V6 bellhousing that was made for a 7.85" input shaft? Are you using a T-5 transmission with a 7.18" input shaft? Are you using a M-II 2.8 V6 bellhousing? If the answer to ALL of these questions is yes, then you need to use the pilot bearing input shaft extension adapter.

In any case, you need to make sure that the throw-out bearing support tube is (a) the right O.D. for your throw-out bearing and (b) is long enough to properly support the throw-out bearing at full clutch release stroke and (c) is not long enough to contact the pressure plate release fingers (note that the pressure plate release fingers move outward as the clutch wears).

It is also important to use longer flywheel mounting bolts to make up for the thickness of the mounting flange of the pilot bearing input shaft extension adapter.

The bell housing is D4ZA-6394 CC.

I'll measure the total input shaft today. The throwout bearing already sits perfectly on the input shaft bearing retainer. I believe the retainer has also been shortened to 4". Again, I'll verify everything tonight.

Attached shows the tag of the transmission. V6 Mustang tranny. 1352-236

Did some digging and I have the longer input shaft.

ROCK, Goto http://danr.mhartman.net/
below my signature element and you will find a PDF on Converting the 2.8 V6.

It is in Alphabetic order from A to Z

As previously noted, the "... Jose spacer plate" allows the use of a T-5 with a 7.18" (V-8) length input shaft behind a Ford 2.8 V-6 with a M-II bellhousing.

IF you are using a 1352-236 T-5 transmission with a 7.85" input shaft and a M-II bellhousing, you should not need to use the "... Jose spacer plate." IF because it is easy to change the model # tag on a T-5 transmission.

When I first started my V6 Conversion, jose was not making an adapter but would refer another gentleman if you needed one.

Following jose directions, I decided to do make my own adapter/spacer plate like some of the other V6 Guys had done.

A picture is available of my Adapter/spacer plate in my PDF.

Then after lots of trial and error I figured a way to make from bronze oil based bushing materiel a bushing that would support the input shaft for both of the lengths (7.18 and 7.85). Kelly Mathis was the person that convinced me to use a bushing for the 7.85 (longer shaft) because it was only being supported by 1/4" on the end of the input shaft (Spud).

Another note of interest is that the input shaft (spud) does not need to be turned down in a lathe as jose recommended. I have never needed to reduce the "spud" on any of my V6 T5 conversions.

Rock, If you are planning to utilize an external hyd release slave you will need to modify the Mutt II Bell housing as pictured in my PDF.

The slot/hole that the former clutch cable was secured in needs to be ground off to allow clearance for the Slave Cylinder.

Update: I have the longer input shaft. We milled down the pilot bearing shaft to the proper diameter. We have milled the throw tube down to 4.5" from the back of the flange to the end of the tube. I will grind the bell housing where the original slave was. All set to go.

Why 4-1/2"? The measured length of the throwout bearing support tube is not important. What is important is the clearance between the forward end of the throwout bearing support tube and the pressure plate release fingers.

Not sure if I understand your meaning..."the original slave" ? The original stock Mutt II had a cable hooked from the clutch pedal to the "side" lever on the bell housing.

 

[Rockonp04]

The bell housing has been ground down on the side to allow for the new slave cylinder on the 2.8L engine. 4-1/2" has been passed down to me as the correct length via this blog post which follows Jose's kit closely.

DanR has 4" for the bearing retainer throwout tube.

Guess I'll find out who is right.
