Super A - front whee removal

denglish · Nov 30, 2015

I went to remove a front wheel on my Super A this weekend and I was a little surprised it didn't just slide right off when I removed the retaining nut and tugged on it a little, and then a lot. I resisted hitting it with something.

I am assuming it is okay to use a puller when the wheel is really stuck on the spindle. Is this okay? Is it common?

The outer bearing looks okay and there was a lot of grease. I just wanted to make sure it is okay to put a puller on it and that I wouldn't hurt anything.

So lets get this straight. You pulling the wheel or you pulling the hub. If your pulling the wheel yes they do tend to get rusted in place and can be hard to pop off. If pulling the hub the grease seal some times sticks and makes it hard to pull the hub off but a few taps with a hammer should free it

Yes. I am pulling the hub off the spindle. I wiggled it and tugged but it is stuck on there pretty good.

It needs a new tire and I wanted to pull the whole thing apart, paint the hub and rim and repack or replace the bearings.

Normally it should come off easily, as you expected. The inner ring of the two conical roller bearings do NOT have an interference fit on the spindle.
As Old says, the seal may cause some extra resistance.
If the wheel does not run true or the bearings have a lot of play, something may have gotten crooked and blocking the hub on the spindle, so be cautious in applying a lot of force.

I'd put some puller on it, tighten it firmly (though not overdone) and give the inside of the hub a few whacks with a wooden/rubber mallet.

Thanks for the suggestions. I'll whack it with a mallet tonight and see if I can get it off.

If you do happen to break that hub I have the front end off an A that had an accident and hit a tree which broke the whole front end off so I have a axle and the hubs here

I had the same thing on an M. I never did get it off.
It's sitting in the back of the shed as a parts
machine.

I think in my case something had worn out causing
a groove on the spindle. I just couldn't get it lined up
just right to get it off. Frustration got the best of me
and I put it back together.

Did your A have the adjustable front axel? Mine has it and my uncle used a cutting torch to make a longer slot at some point when he found he couldn't adjust the wheel width. I wouldn't mind having those parts.

By the way, I hit the hub a few times with a mallet and then a ball and peen. No dice. I will put a puller on next and apply slow pressure. I wish I could just drive it around with the nut off that would surely get things moving! Ha. I'll report how the spindle looks.

Glad you got the hub off and thank you for reporting back to us.
Are the bores in the hub and the cylindrical parts of the spindle where the bearings sit still intact? Any idea why the hub was so hard to remove?

Note: On the inside end of the hub (where the large conical roller bearing is) there is a thin wear sleeve pressed into the hub. The seal is fixed to the spindle and rides on the wear sleeve. That sleeve will probably need to be replaced. See your parts manual.

[size=18:23bf0b98de][/size:23bf0b98de]Everything looked okay to me. The metal wear sleeves in the hub and the spindle are intact. I was unable to pull the larger inner bearing off with my hands. Also, I cannot push the small bearing back on the spindle. It will need to be tapped into place using a socket or some such.

Any suggestions on pulling the big bearing off?

Hub probably hung up onthe seal

denglish · Jan 29, 2016

Just a little follow up here. I put that wheel back together with a new rim and tubeless tire. Last night I took the other wheel off and the hub slid right off of the spindle. It appears Gene was right regarding the need for a puller on the first wheel. On the one that was stubborn, the pressed-in wear-ring had a pretty deep groove in it. I think the wheel was hung up on that.

On the wheel I pulled last night the hub slid right off and the outer bearing came out easily. By the way, the wheel that came off easy was the right-side wheel on the lighter side of the axle.

common actually.
The inner bearing is stuck on the spindle.
(old grease, rust, spin damage)
Using a puller physically pulls the seal out of the back of the hub so you can get it off.
Once I get that bearing off, I'd check it carefully.
Bearings are relatively cheap, damaged spindles...not so much.

ps next time, as said, pull the wheel off first.
Working with bearings you don't want that weight and long lever bending action. Bearing roller cages get damaged easily.
