ok come on guys tell me the best way to get that little needle roller bearing out from my k5.I have pulled out the top one but my puller wont reach the lower bearing.Any tips or tricks or do i have to split it with a chisel?? :?

I had to remove them from my 250. It can probably be done with a bolt, nut and washer. washer just small enough to pass thru, then push to one side before tightening or pulling. I wouldn't want to use a chisel or any of that because you don't want to chase needle bearings or races. I tried chasing around ideas and friends with lots of tools  or ideas, but after a week of hunting, I found the tool.
  Its called a blind hole bearing puller. A kid about twenty years old and with about that many piercings in his head, had it out in less than a minute. It spreads as you tighten it and is attached to a slide hammer. "Bap, bap, bap," it was out. That bearing doesn't need to be removed very often, so I didn't see a reason to buy one.

ive been looking for a blind hole bearing puller but as im a cheapskate i dont want to pay ?100 for something i wont use often.BUT i think i may try and borrow one.

jonny500:
ok, you can try the washer and bolt idea it dose work some times. i have a way that also some times works. you need to go to a builders merchant with you casing and find an anchor bolt like in the pic below, you may need to mod it with a grinder/file and some how attatch a slide hammer weldingg is good. befor tring to remove alway add some heat from gas torch, or stick it in the oven at around 150 (providing none of the seals in it are needed)

Polar-Bus:
You might not need an expensive blind bearing puller. Try this it won't cost you a dime to try.

1) place the clutch cover in the freezer over night.

2) quickly heat the case near the bearing

3) rap the case off a wood bench top and force the bearing to slide out of the bore.

you might need to do this a few times but the bearing should come out. I use the "freeze-n-heat" method on blind bearings all the time. Works awesome.

You can install bearings by reversing the method. Place the new bearing in the freezer overnight, then heat the bearing bore (or just place the whole case in the over at 300F) and the bearing should press in with your finger, or a light tap of a hammer)
