New Guy With a Question

Hello everyone.
I'm new here and want to introduce myself. My name is Paul from Glendive, Mt. I'm beginning a restoration on a 1940 Ford pickup.

I have a question about the intermediate driveshaft support bearing 78-4658. How does it come out?

Thanks
 
Hi Rider, the zerk fitting at the center of the torque tube holds the bearing in place and must be removed, then a special tool can push the old bearing out, and insert the new bearing.
 
Thanks.
I would have tried to beat it out without removing the grease zerk.

I don't have a very good pic and can't seem to upload it. Maybe I don't have enough posts yet?
It is the truck that took my grandmother to the hospital when my dad was born.

Your picture problem is probably that it is too large. Email it to me and I will upload it. We will work out the details for the next one. Number of posts is not the problem. What hardware and software are you working with for your photos?

KR Wilson made special pullers for installing and removing these center bearings. Do not attempt to do it using crude tools such as a sledge hammer. I have used mine many times and it is difficult to get the grease holes lined up even with the correct tools. By the way the zerk fitting has nothing to do with holding the bearing in place.
 
You can remove your driveshaft and inspect the surface where the bearing race is located. If this surface is still looking good I would not remove the bearing. These bearings are scarce and usually cost $200. or more.
 
I'm going with Larry here. It's not a bad idea to replace but if it's doing okay... I'm still running the originals. If you are going for a full rebuild best I can suggest is skips.

Hi Larry, From my initial answer to the question, you can probably tell that I didn't have the tools nor the expert advice, and farmed my own torque tube out for the bearing replacement. I've always been under the impression that the final placement of the zerk assured that the bearing would remain in correct alignment. Can you please explain that point further?
 
HD Rider: Do a search on "Install torque Tube Center Bearing" and lots of info. appears.
I did replace mine.
 
If you can find a local Ford Club guy with the KR Wilson tool it is pretty easy. I have the tools and if you lived in the area would be more then glad to show you how they work. It can get ugly if the rubber part is fused to the inside of the torque tube and you pull the bearing out but the rubber stays in. New, the bearing is inside a rubber doughnut with a hole to let grease into the bearing that must line up fairly close with the hole the grease fitting screws into.

Welcome to the forum, there are many 40 owners here and many have pickups.
 
I am only able to comment on changing the original style center bearing with the hard rubber outer shell. Once the bearing has been pulled into position the friction between the rubber and the driveshaft housing is more than enough to prevent any movement. The zerk fitting threads into the housing and does not enter into the rubber bearing shell.

I know that Skip Haney offers a replacement that is quite different from the original. I am not familiar with has product but perhaps he includes a longer version of the zerk fitting to lock his bearing into place. Someone may be able to comment on that.

Here is what the NOS bearing looks like. Note that the grease can get to the bearing if the line up isn't perfect.
I just installed one of these in my 40 coupe torque tube. I don't have any extras.
 
Howdy HD - I'm on the other side of the state.


Sounds like a great truck with family history - doubly cool.


Welcome!

Welcome to the barn, looks like you have great history with the truck. Pictures for this site can only be 800x600, I find if I crop a picture I can usually upload it, otherwise I run it through some software that converts it to that size.
