tao tao cy150a tire change By scooterwill (Read 1,106 times)

Ok, I got a flat tire last week, ordered my new tire, prepared to change it. Removed the exhaust system, used a puller to get the swing arm off. But the tire still wont come off. Any ideas?

I'm not sure what happened.

Why are your swingarm bearings on the axle? They're usually held in the swing arm with circlips. Your bearings are frozen on the axle and need to be pulled off before the wheel will slide off.

How did they manage to stay there and how do I get them off

[kz1000st]

I don't know why they stuck there but if you can get a puller behind the one next to the wheel that might be a start. I hate to say put a pry bar or big screwdriver and lever them out, but.........

You might find a crumpled circlip between the wheel and the bearings and one still in the swing arm. If the bearings weren't greased on the axle at the factory they probably rusted on the shaft.

Try soaking them with Liquid Wrench or WD-40 before you try to pull them, give them like overnight.

What if I put the swing arm back on, would they reconnect or is that false hope.

That's not going to work. The bearings are held in place by a clip or something. That failed to retain them. It happened because the bearings are frozen onto the axle. I'd say heat them with a torch but I also see a seal that would suffer from it. You could try a real good hair dryer but it might not generate enough heat. Pulling with force on the wheel might work but be aware if the bearings are sinking into the aluminum, it's not working.

I agree with Kz. From looking a photo you posted it appears rusted. MO would be to spray some rust buster on it & let it set for 20,30 minutes then try it.

Ok, so I've been hitting it with wd40 a few times a day, still not moving, it spins on the axel but will not slide off.. any other ideas?

There are some expensive real good penetrating oils, that are a lot better than wd40 which isn't a real penetrating oil, plan to spend $10-$12 a can and they stink a lot more than wd. They can actually dissolve rust.

I guess being nice is over. Do you have a torch, like a Burnzomatic? The bearings will have to be heated to make them expand on the axle and then levered off. It looks like a space behind them is available for a small prybar. Once you break the stiction they'll probably slide right off.

Are you saying the inner race is spinning on the axle? If so then there is no need for more oils or rust fighters.

Get a good puller that can reach behind the bearing and get on the inner race directly, or if not directly then on as much of the bearing as possible. See if the puller can put enough pressure on the bearing to make it move enough to get it off the shaft.

My opinion is that pullers are much more gentle on the products. Hammering and prying can create damage to the bearings but also on the parts used for the pry bars to force against.
