Torque Tube to Differential Seal
 

I need to replace the seal on the torque tube. The gasket is one piece. Does the tube slide out and back in easily or would it be better to split the gasket and install it without separating the tube from the differential?

need to know what year tube we are talking about

Re: Torque Tube to Differential Seal
 

Not sure what year yours is but on a 39 , you would have to split or at least cut the gasket in one place ( preferably the top ) and slip it in and on after removing the bolts . The drive shaft is connected to rear end or I should say pinion gear via coupler that has a pin driven in and flattened and the only way I know to put a gasket on without cutting the gasket as described would be remove rear and torque tube , un bolt tube, drive out pin , yada , yada.

Exactly which gasket you referring to ??

Re: Torque Tube to Differential Seal
 

It has been my experience that on a 40 Ford if you are referring to the gasket that fits between the rear of the torque tube and the rear end housing you need to remove the torque tube and drive shaft if you don't want to cut the paper gasket. It's a lot of work.

I did forget to put one the clam shell gasket in place before sliding the drive shaft into the U-joint and transmission and DID cut the gasket to make it easier. I installed the cut at the top of the clamshell. Worked fine. No leaks. Use Permatex.

Personally, I would first try to install it by cutting the paper seal and installing it after removing the rear end bolts and unbolting the rear radius rods. I think that would allow the torque tube and drive shaft to slide forward and give enough space., HOWEVER, I AM NOT SURE ABOUT THIS. Others may know for sure. Make sure to use non-hardening Permatex and install the cut at the top of the housing. I made my own gasket .

DON'T CLEAN OUT THE REAR END THREADS WITH A TAP AND DO TRY TO INSTALL THE BOLTS IN THE SAME HOLES THEY CAME OUT OF. I NUMBERED THE BOLTS & THE HOLES BEFORE TAKING IT APART.

Get a tube of right stuff sealer, use it to replace gasket, clean off oil before sealing

Re: Torque Tube to Differential Seal
 

Make sure homemade gasket doesn’t block the drain back hole from the tube to center section

The drain hole that the pencil is pointing toward. DD

Mr strech cab still hasnt responded back as to what year he is working on. must not be too important. the reason I ask is the later ones with a bearing in the middle sometimes do not play nice

Re: Torque Tube to Differential Seal
 

Sorry for the delay and lack of pertinent information. My car is a 36 Fordor Deluxe.
And thanks for the information. I will try and install new gasket by splitting it at the top.

Re: Torque Tube to Differential Seal
 

As I recall, getting the torque tube off isn't that big a chore. You'll have to remove the speedometer turtle and find the clip that retains the drive gear to the drive shaft. Remove that clip, slide out the drive gear and bearing and you should be able to remove the torque tube. (Please correct me if I'm wrong. It's been a few years since I was doing a rear.)

Re: Torque Tube to Differential Seal
 

Wow Pete, you omitted lots of steps. To remove torque tube you have to pull the rear end.

In a previous post Stretch Cab already had the rear out asking questions on best way to remove the spring. Now maybe he's already put it back in place, and now wants to replace the gasket between torque tube and rear banjo housing flange. Who knows for sure :)

Re: Torque Tube to Differential Seal
 

Everything is still out of car and in the process of being painted. I have a new gasket on order and want to be ready to install it when it arrives.

Re: Torque Tube to Differential Seal
 

If you already have the torque tube removed replace the clam shell 0-ring with this.

*Note: picture #2 in this ebay listing shows the '35-'36 rear transmission mount and the universal clam shell cover upside down. I just wanted to mention this because I have seen some vehicles put together like this, requiring disassembly to correctly assemble these parts.

Re: Torque Tube to Differential Seal
 

One of the old tricks to seal up leaks on the axle housings and torque is to loosen the bolts and separate the mating parts enough to put a few wraps of dental floss in the gap then tighten everything up.

Re: Torque Tube to Differential Seal
 

Thanks Ken, never heard of that. Sure beats taking it apart and installing new gasket.

Re: Torque Tube to Differential Seal
 

Good posts on this.

Re: Torque Tube to Differential Seal
 

Since the axle is out, I would take the turtle off along with the little snap ring at the front and pull the tube. That way you could inspect the front roller bearing and sleeve and replace if needed. I would also replace the front grease seal, noting how it goes in backwards. The new gasket could be slipped down over the driveshaft and put in place uncut when reassembling the torque tube.
