New front wheel hub

[CMoore]

Looking for advice, I had to replace the passenger side front wheel hub and the fit is so tight that I can’t get it on without force. Tried the old hub and it slides right on. I understand wear on the old hub, but is there something I need to do with the brakes to install new hub to fit right?

Welcome CMoore!

Is your hub complete with a new drum as well? It sounds like to me that the inner bearing race is too small on the I.D.? If you would, drop us some pictures to see exactly what you are seeing please. Dr. Dana will be by shortly to offer his professional expertise.

The hub seems to be rubbing on the brakes. I will get pics soon.

[CMoore]

Yes new drum as well

I am not sure what exactly we are talking about here. What vehicle do you have? Definitely shoot some picks. If you are talking about the Drive Hub that connects the axle shaft to the drum hub, that issue is common. The fix is fairly easy.

Sorry, it’s a 47 CJ2

Sounds dumb, I’m trying to figure out how to upload pictures

CMoore, go to "Go Advanced" Scroll down to manage attachments, Select "Browse" pick a file and then select "Upload". One file at a time and there is a limit to the photo's per post, as well as the size. The "Attachment Key" has the size limitations and file types that are up-loadable.

Hopefully this will help you see what I got. I slid the bearing on, no problem. I seems to hang up on the brakes. I was just wondering if there is a way to compress the brakes or what else should I try? Sorry, I couldn't upload a picture with my phone, I had to go to the laptop.

There are locking nuts and eccentrics on the back of the backer plate.

You can loosen them to get some slack in the shoes and then readjust them. It looks like the shoes might have been adjusted way out for a drum that had been turned to clean it up.

Larry is right on it I think. It looks like as the brake linings wore they were adjusted out to compensate. If the drums have been turned (a common practice) as LarrBeard suggested, it would exasperate the situation. These brakes are discussed thought on many forums. the reason is they can be a bit "finicky" to adjust. You will need to adjust the shoes all the way in as covered in the manual. Then the drum will go on.

If you have a Universal Service Manual for Jeep Vehicles, This is covered in section P-6.

There is a discussion on brake adjusting here. https://willysjeepforum.kaiserwillys.com/showthread.php?1421-well-the-darn-thing-is-out/page59&highlight=brakes

If you search this forum for "Brakes" it comes up a few times.

I strongly suggest that you get a Service Manual for the 'lil critter.

Here is an excerpt from the manual, taken from the KWAS web-site:

I think you're going to be fine.

It worked! Thanks for the advice. I do have the manual but didn’t understand these kinds of brakes. I am a aircraft mechanic by trade and this was the first time to mess with them. Thanks again everyone!

"I am a aircraft mechanic by trade"

Just way too simple - you overthought it.

And that hub looks a LOT better - the other one had been chain whupped.

Glan to have been a little help. Show us a picture of the rest of the Jeep.

It’s just a ranch Jeep, but one day I’ll do restore the thing! It’s been garage kept for years. It’s still a 6 volt which I want to change. Are you military?

Very nice looking vehicle.

It's not "just a ranch Jeep". How many 73 year old vehicles are still working for a living?

A. At one time I was a Senior Chief Electronics Technician in the USN/USNR.

B. I also spent 40-years working in industry as a tech/engineer/manager for military radios and avionics. I love crawling thru airplanes. P-3C was my favorite, EA-6B second. F-4's rule!

C. There is nothing wrong with 6-volt systems except the headlights are as dim as candles. Good cables, clean connections, good brushes in the starter, right oil in the engine and it will start from Greenland to the Sahara desert.

Keep em flying! I’m an F-16 guy for 27 years so far.
