250R Airfooler Motor Question

[Tatersaladx]

I was wondering if bearings, and other parts from a CR250 Elsinore would be interchangeable.

Yes 78-80 only the clutch is the same and all the bearings are the same only it has no counter balancer so no bearings there.

[1upfront]

Also the whole tranny is the same layout so I imagine it would also interchange, all of the seals should be the same aswell.

thanks thats really good because i found a bearing kit for the 78-80 Elsinore bottom end, and cant seem to find one for the airfooler

If it's crank bearings you need bike bandit has factory atc 250r ones also the manual has a special procedure for replacing the crank bearings and seals let me know if you need instructions.

[Tatersaladx]

I was gonna order those from bike bandit in the first place, and when im replacing the crank bearing ill just pm you for the instructions.

Special instructions???? I popped out the old ones. Put the new ones in the freezer for an hour. Bearings that is. Put a little heat on the case and tapped them in. Did I do this wrong? I dont think so. Not bashing, just wondering.

[1upfront]

It requires heating the case they recommend an oven and freezing the new bearings and it makes the process easier, I've also just punched them out cold with a brass punch and a hammer.

[Brockey]

Now I see. So yes I did it right. I knew I did nothing wrong.

mine arent to hard to get in/out. requires hammer tapping. NOT beating.
the crank bearings and seals can be had off ebay for about 40 bux shipped. they seem to be good, no problems yet.
