Well I took my wheel into a local motorcycle bussines which fixes bikes and they used their bearing puller to pull the bearings. Only cost me $5.00. Ironically the Evaporust loosened up the frozen bearing on the sprocket side but it is really growly. I see they are 6202 bearings and they are in a cup which is pressed into the hub. I may improvise a homemade bearing puller to pull it from the cup made out of a bolt and nut heavy duty thick washer. Do they pull easily from the cup?
The Evaporust really did a great job on cleaning up the rim. The powder coating place said you need to remove the wheel bearings since the parts are baked at 400 degrees and the bearings dust shields can melt at that temperature and it could be harder to get the bearings out if you fail to remove them before powder coating. The powder coating place says they sand blast the entire rim to put a roughened tooth on the chrome so the powder coat will adhere well. They told me it looks much like real chrome and it will pretty darn durable much more so than paint.
I will get new bearings too. I seen them on Amazon but I want to get a decent set what brand to you recommend? I see Blackwidowmotorsports has them. I was talking with th guy at the place and I told him it's from a Rupp Roadster 2. He is about my age and said they were about the best minibikes made during the 1970's. I told him I have a newer Tecumseh HS40 but I want to put a mildly modified 212cc clone on. He said those clone engines are crazy powered and he used one on a go cart for his nephew and he said compared to the old worn out 5hp Briggs which was on it he said it is now crazy fast. He agreed that the Rupp will be a little speed demon with a Honda clone on it.
