November 2, 20169 yr Hi, I just picked up a clean 2009 evo 250. Yes its the snappy frame and swinger model but it looks ok to me for now The rear wheel bearing needs sorting out do i got the part number from the parts list 61904. Thinking back to when i did my KTM i was told to buy a decent third party bearing to the same spec. Then i was told to buy the full KTM kit which included dust covers and the internal spacer. Whats the craic with these then? Just grab a decent make one from Ebay orr off to the stealer? Anything else i should watch for or have spare in my toolbox? BTW the map switch, 1 is full power right? Cheers Jon
November 2, 20169 yr Wheel bearings from a trials dealer under the Apico brand will be quite sufficient - fairly cheap probably less than a tenner the pair, knock old ones out, clean up spacer, pick off seal, pack new ones with clean grease replace seal and tap in. Easy job and will last for a couple of years hard use.
November 2, 20169 yr These bearings are quite wee, you will need to keep an eye on them. Failure of wheel bearings can be catastrophic.
November 3, 20169 yr Author A guy also told me that the standard codes will likely say 2RS (2 rubber seals) he said always pay more and get the 2SS (2 stainless seals) and you wont have to worry about them for longer.
November 3, 20169 yr You can greatly extend the life of RS bearings. Flick out the seal with a very fine screwdriver, clean the bearing with 2T mix, dry then repack with good grease and push the seal back on.
November 14, 20169 yr Author Bearings have arrived and quite wee is not the word. They are tiny! no way these are the right ones! (61901 / 6901) Oh well, i'll get the wheel off and soon see
November 16, 20169 yr Author Well I installed the correct ones last night. For anyone attempting this and doesn't know let me share a tip albeit obvious to most. On my KTM it was possible to move the inner spindle just out the way to get a drift in from the other side. On the beta this was not the case but it was possible to fit a smaller socket to the inside of the bearing and hit the lip of the spindle to knock the bearing out on the other side. I applied heat to the other side before bashing away.
