Torque Tube Connection to Transmission
 

I hope the pictures posted. This is the connection of the torque tube to the transmission, looking up at it. There is a space between them. The bolts will not snug down, and, I am afraid to really go after them because the whole bolt seems to move, as if it will come loose? What is going on here? Can I leave it as is? The prior owner had it frame off, engine and trans and rear out.

It's possible the threads on stud or transmission are stripped. So to find out you turn and tighten nut. If stripped it must come out and there are various thread repair kits. If ok, Christmas came early !

Good Luck

Re: Torque Tube Connection to Transmission
 

I could be wrong maybe those studs, bolts didn't go in transmission, but the adapter. Could be a bigger problem. Help please !!

Re: Torque Tube Connection to Transmission
 

Those bolts should have a D head that keeps them from turning.

Re: Torque Tube Connection to Transmission
 

It appears the rear transmission mount is well beyond its life expectancy. I am certain the rectangular heads of those bolts are simply spinning within the old / soft rubber. There is no way to get in there to hold them.
Time to replace that mount.
By the way, get one while you still can. They will not be reproduced again and when they are gone, well, you will be up sh--- creek.
Mike Driskell sells a quality reproduction at a fair price.

Re: Torque Tube Connection to Transmission
 

Is the inner cone in there? Looks like a 33-34, correct?

Re: Torque Tube Connection to Transmission
 

I see that mount on that website. It is $290! Correct? And that is 100% the problem? Will the transmission leak as is?

Re: Torque Tube Connection to Transmission
 

No, it is a 35.

Re: Torque Tube Connection to Transmission
 

I can't help but wonder if whoever threw this back together used ordinary fasteners. That might be why you cannot tighten them.

Re: Torque Tube Connection to Transmission
 

Correct bolts from 3rd Gen

Re: Torque Tube Connection to Transmission
 

This is an inside look. If the rubber mount has disintegrated the D head bolts could turn when tightening.

I just stuck the bolts in for the picture. I see two are in backwards lol.

I wonder if there is any way a 1940-48 transmission mount could be adapted to fit your car. The bolt set up is more accessable.

Re: Torque Tube Connection to Transmission
 

He said that he has a 1935 Ford. The rear support (which also incorporates the rubber vibration ring) has the flange on the one side for mounting the parking brake lever. I don’t know how he’d be able to mount the lever to any of the 1937-48 rear support castings. He’d be smart to replace the 48-5089 rear support with a new one.

His photos suggest that the retaining nuts are not secured properly…..one looks ready to find its way to the road. I can’t remember if Ford used lock washers under the four nuts but they should be secured better. Locking nuts or slotted nuts with safety wire would keep the OP sleeping better at night.

As Kube points out, the “L” head shape of the four bolts is designed to sit in the slots molded into the rubber ring. His old rubber isolator has passed its expiration date I believe.

Re: Torque Tube Connection to Transmission
 

Ugh. I believe Sacramento Vintage Ford will revulcanize an original one, but they get $75 per. Thanks for the heads up. I'll pick one up from Third Gen to have in stock.

Re: Torque Tube Connection to Transmission
 

This is all great stuff, thanks to everyone. I will disassemble and see what I need.

Re: Torque Tube Connection to Transmission
 

My advice is to buy reproduction parts you need now while you still can. Sources of reproduction parts are drying up fast and there's no good way to predict when or if things will no longer be obtainable.

Re: Torque Tube Connection to Transmission
 

Third Gen Auto in Tenn also has the proper special size nuts for the bolts. I believe the big nuts on your studs are jammed against the steel cover for the U-joint. You will not get the proper assembly with the nuts shown. The U-joint cavity is filled with lube which is going to leak out and the U-joint will be damaged over time driving.

Re: Torque Tube Connection to Transmission
 

Terry, I was thinking the same thing. They look fairly large. So glad Third Gen is making these nuts. They are almost never found in the wild. When they are, I hoard them like a squirrel for winter.

Re: Torque Tube Connection to Transmission
 

Those undersize nuts are hard to find. Seems to me there is somewhere else on the car that uses them, but I can't think of it now

Re: Torque Tube Connection to Transmission
 

Terry, YES, you are absolutely correct! I was thinking that this is the way it is, these nuts are hard to tighten, being so close to the mount. I never considered that they should be smaller sized, but you got it!

Re: Torque Tube Connection to Transmission
 

Pics of 5/8 and 11/16 20 tpi hex nuts. The original in the Green parts book indicates a slotted nut and cotter key. My replacement bolts in a previous post are not drilled for the cotter key as also the ones that I see advertised at 3rdGen.

Re: Torque Tube Connection to Transmission
 

The green parts book show the castle nut as 34031-S and the regular nut as 33881-S.

Re: Torque Tube Connection to Transmission
 

Hex nuts hanging up on 'clam shell' because their heads are too big? Should be 5/8" across flats, not more conventional 11/16".

Re: Torque Tube Connection to Transmission
 

Re: Torque Tube Connection to Transmission
 

Third Gen mentioned in the new products thread that he has the correct nuts in stock.

Re: Torque Tube Connection to Transmission
 

They are listed as "upgraded tall nuts" but like the replacement D bolts are not slotted for a cotter key. I am quite sure they would be just fine IMHO!

Re: Torque Tube Connection to Transmission
 

Would it be possible to file the bigger nuts down to 5/8 across the flats?

Re: Torque Tube Connection to Transmission
 

I could do it in my mill quite easily but I think just chucking them in the lathe and turning a little taper towards the bottom would probably give enough clearance. I could put all four nuts in the mill vise removing 1/32" from each of three flats. It would take 3 passes and then the other three flats the end mill would need to be lowered another 1/32" for the remaining 3 flats. Would not take much time at all. More fun than buying them too!

Re: Torque Tube Connection to Transmission
 

I've made special nuts for that application. A lathe is your friend.

Re: Torque Tube Connection to Transmission
 

What is the context, was this same torque tube, or new build etc.

Looks like a 33/34. I know there is a difference in length between the V8 and 4cylinder. I went through this few years ago trying to connect a 4 cylinder torque tube and shaft to a v8.

It looked just like that, too short.

Re: Torque Tube Connection to Transmission
 

This is a 35 Ford 2 door sedan. The prior owner was doing a complete restoration. He took it off the frame, took the engine and running gear out, then started to build it up. He got the body on frame in primer with the front end off, engine in but intake not attached. He passed away at that point in about 2008. I just bought the car in October.

Re: Torque Tube Connection to Transmission
 

Then the correct nuts may be somewhere in one of the boxes you purchased or lost to time. I would take it apart first to see if they had the rubber done/replaced or not and if the bolts are the correct ones. It is difficult to put a car back together that you did not take apart. Inspect all prior work carefully this may be an indication of their lack of attention to details or a simple mix up of fasteners.

Re: Torque Tube Connection to Transmission
 

It will probably take a while but I am going to take it apart and see what I have. Now that the Ford Barn has provided so much good information, I know exactly what to look for.

Re: Torque Tube Connection to Transmission
 

If it helps at all I modified some nuts for this application. I took some 10mm flanged nuts and ran a 7/16 UNF tap through. I might have turned the flange down a little too. These 10mm flange nuts use a 15 mm hex, which is 1mm smaller than even the reduced hex on the 5/8" hex nuts. They worked well and a 15mm socket fitted well in the space available.15mm is approx 19/32"

Re: Torque Tube Connection to Transmission
 

Oh no Mart!! Using a METRIC socket on a Ford? Shame on you! LOL I suppose you even drive on the wrong side of the road over there!

Re: Torque Tube Connection to Transmission
 

Yeah, he should at least use a Whitworth socket.:D
