Removing Rear Wheel Bearings? By randall (Read 901 times)

Hi,
I need to remove and replace the rear wheel bearings as they had suffered ingress of water during my bikes hiatus with its careless previous owner. It's a 150cc GY6 based bike. There are two bearings pressed in the tube and I was wondering if I could remove these by just bashing them both straight through. Looking at the small gap between them however, it might almost appear that there is a spring clip between them, so perhaps the brute force approach may not be wise?

Anyway, any tips on properly removing these?

I just removed a bearing in my rear swing arm. Yours sounds different, but the way it was explained to me (and what worked, getting the old out and the new in) is to heat the area around the bearing with a torch or heat gun, then bang out the bearing using a hammer and a socket bigger than the inner diameter of the bearing.

Randal look at the 150 Velux parts manual on page 40 for the breakdown diagram and you'll see two locking circlip rings and they are the standard 6301 bearings that should come out easily:

Hey JR,
Yup, saw that in the parts diagram, but the circlips retain the 2 running seals which are not shown there. Well, you could say the circlips retain all 4 parts, but the bearings are well stuck in there. I've put a puller on them but I was afraid to torque down too much on it in case there was a lip or another circlip between the 2 bearings. I'm starting to think there's nothing between the bearings, though. I've been giving them a good penetrating oil soak for a couple days while I bust my new tires on, so I'll try again. Worst case I'll just cut them out!

Mike, I had tried pounding them through with a socket, but they were not budging a bit. I think they are just rusted in.

Turns out they are actually 6302's.

Randall since they are no good you can take a propane torch along with the penetrating oil and heat them and they should let go and drive out.

Got'em out. Took some persuasion, in the form of a 5 pound sledge, but they finally came out. Got the new ones in, bike is back on the road. Oh, and the new Michelin City Grips I just put on are a dream! Wow, everything is smooth and quiet!
