rear wheel dust hubs

[bulleteer]

I am trying to replace the bearings on my rear wheel, but am having difficulty getting the dust seal off on the right side. It seems pretty well entrenched. Is there a way to get it out without ruining it? And if it is damaged, where can I get another? I don't think they are made any more.

Thanks in advance for your help.

Can you drive the bearing out from the opposite side with a long punch? I think you should be able to. That will drive out the seal without damaging it, and the left side bearing, I believe it is, is no longer available anywhere. Do you already have the new bearings, and if you do where did yoy find the left side one?

Bearings and seals were available as of last year. I bought my seals and the one wide bearing from Yamaha. The rest of the bearings ar redily available.

The right bearing is actually the one that feels rough, but I was told to replace them both, that both were available from bearing suppliers. I suppose I should find out first. I have tried to knock the seal out by using a long drift from the left side up against the bearing, but to no avail.

[DiverRay]

If you have a propane tourch, warm up the hub. Warm the side near the bearing, from the spokes, and then try drifting out the bearing and seal. If I remember, there is a "spacer" between the bearings. You will need to be sure you are NOT trying to drive out the bearing with the spacer.
Good luck,
Ray

It's always a good idea to have new parts in hand before taking something apart. It would suck damaging the old parts before finding out they are obsolete.

I just checked Bikebandit.com, and they have both rear wheel bearings it seems. The right side is $11.37, and the right side is about $34.10.

Eureka! A little bit of heat and the seal popped out without damage. Took out the circlip (reason why I couldn't use the bearing to push the seal), out came the bearing and the left side was a snap.

A little background here. I've had this bike a month and when I got it, it was a mess. I started just cleaning it up and one thing led to another, and it is now a full blown restore, well almost. The engine runs good, fires right up and idles nicely and will be pretty much left alone. Today I was taring apart the rear wheel and brakes (rebuild master cylinder, calipers and new pads) and felt that the right bearing was rough, hence thought it might be a good idea to replace.

I also checked at bike bandit and found them.

Thanks for all your help.

This bike might be on the road by Easter. Fortunately the RE is carryin me through the winter.

As an fyi, Zanotti's has the bearing and oil seals. $8.80 for the right and $26.41 for the left. They also have the oil seal, comes to $52.00 for everything, including frieght.

And as of two weeks ago. I picked up three from yamaha. They're $30 sumptin' bucks apiece. Got mine for mid-twenties (dealer exchange)... so that Zanotti's price is REAL good!
Oh yeah... Use the old bearings to press/hammer the new ones into the hub. Take the old bearings to a bench grinder and grind off a few thousandths from the outside diameter. (Prevents them from sticking in the hub with the new ones)

Think I saw on UK site that they have made some.

Thats how I do it.

Also have several different sizes of tubing which I use to drive some bearings. When end of tubing gets mangled I cut it off w/pipe cutter to make it "square" agin.

"Wow man... totally tubular!"

MRO, I use a length of old fork tube to hammer down new steering bearings on the lower tree.

[DiverRay]

Darn, and I spent money on a real tool!! But then, that was twenty something years ago

My fork tubes are still attached.

If your interested, I've got a set of "seal" drivers that are NOS. Bought years ago and never used. CHEEP (gust never seemed to fit the seals that needed driving)
