T5 transmission to Iron Block M116/117 - Page 3 - PeachParts Mercedes-Benz Forum

I just assumed it was a needle bearing-it's all gone but the shell. After more careful measuring the pilot bearing bore I got 1.3775' which is close to the logical 35mm so the Ford bearing might fit after all.

Got the Ford 1.379" OD bushing:

Froze it and started to install it but it seemed to go in easier than I expected so I stopped and pulled it out before it warmed up and much went it. I measured and found there is .001" of interference which corresponds to the bore being 35mm. I would be more comfortable with a little more interference. I'm thinking about using a high strength/high temp sleeve retainer product like Loctite 640. If the bushing ever needed to be removed it could be drilled out and then split when thin.

I just grabbed a t5 from a 2001 v6 mustang yesterday. I. Didn't take it but it had a needle bearing pilot. Like a sleeve witb a thin wall caged needle bearing in it do that rides directly on the input shaft pilot tip. The trans is yge same as the sn 95 5.0 units with the 3.35 first gear sets. Rated at 260ft lbs. They will take considerably more. Check those bearings out maybe.

I have heard bad things about the needle bearings breaking up and ruining the transmission. Nothing can go wrong with a bronze bushing except normal wear so I feel more comfortable with that. I thought about pursuing the later T5 with the flange output but in the end it looked like another hurdle and the slip yoke interface should work good for me. I might go out to my storage unit and try to raise up my coupe and mock up the transmission so I can get measurements for the driveshaft and check shifter location.

This is a slip yoke trans. 2004^ are flange i believe and have the remote shifter. I did grab the DS with slip yoke rear bolt on flange yoke and even the splined flange that bolts on the pinion gear. I was gonna grab the axle but it had a ton of play in the gears and it was only a 7.5" not a 8.8.
Its been a long time and it was a 6 cyl but I think I had the shifter in the right place aprox with the sn95 style t5. I

Pilot bushing installed. It is .75" deep and has .25" extension which gave me the .75" pilot engagement I wanted. Crank turns with no binding or interference with the input shaft. Next is to install mock up in the car to determine drive shaft length, shifter location and trans mount design.

Tony,

Is the steel shell of the pilot bushing part of the Ford supplied piece, or is it an adapter that you made/had made?

Tony H · #38 06-25-2020, 12:51 AM

It is part of the bushing:

I managed to get the transmission mocked up in the car(in difficult storage unit conditions!). The transmission fit fine physically but as I suspected the bulky shifter box hit the floor with about 1.5" to go. I do not want to cut the floor so I will look at another solution-possibly a front shift tail housing with some kind of remote shifter. The other concern is the driveshaft. The small front section is only going to be about 10" long with the longer transmission. It will be difficult to get the correct geometry with such a short section. I am looking into shortening the longer rear section to my rear center bearing mount and having a longer front section made. That would create 2 pieces about 26" each. I looked at the posiblilty of a 1 piece shaft but no way the large tube would fit as the tunnel was designed for the small 1.75" tubing.

I think the clearance issue can be solved with a S-10 tailhousing that places the shifter box at the front where there is ample room. The tunnel is much higher at the front of the tailhousing and I measure several inches of clearance. The later Mustang V6 T5 is similar but uses a bolt on CV joint instead of a slip yoke and a remote shifter. I might give it a better look.

You may have an output shaft lenght issue with the different tailshaft housing. As long as it's a world-class t5 s10 trans you are probably able to swap it though. A non WC may work but I'm not sure. Astro performance can probably help with that if they are around still. It could be the same lenght though possibly. I used to have a chart on lenghts for them. I'll see if I can dig it up.

The WC S10 tail housing is a direct swap. The slip yoke bushing needs to be changed and a S10 shift rod will be needed. There are a few on Ebay.

https://www.ebay.com/itm/S10-Tail-Housing-T5-2wd-World-Class-Electric-Speedo-USED-Rear-Extension-Hsg/173770337335 They are electronic speedo but there are solutions. I'm going to do some careful measurements first.

Tony:

It seems fair to ask what may very well be questions that you have already answered for yourself:
What is the relationship of the original shifter location (the hole in the floor of the car), and the positions of both the Ford, and the S10, shifter locations? Are either of them even close to being in the MB location? If not, how long of a remote shifter would be required?

Tony H · #44 07-19-2020, 05:33 PM

Hi Frank,
The issue is with the current shifter "box" on the Mustang tail housing. It is large and protrudes above the tail housing in a location where the trans tunnel is small (due to the shorter original transmission). Just forward of that location the trans tunnel is much larger. I really don't want to make any new holes. The S10 shifter box is in an area just before the tunnel narrows down so I am hopeful there will be enough room for any shift linkage I may need to extend the shifter. I have seen several viable solutions for the shifter on the net. Just depends on how much room.

Tony H · #45 07-19-2020, 08:38 PM

Also the shifter "Box" is quite a bit larger than the existing shifter hole but it would still hit the floor even if it lined up. The pic shows the Mustang shifter box and the original shifter hole. Also more room at the front of tail housing if you can see.
