A piece of steel tube with a slightly bigger internal dia and a bar to push them out, and press them out in a vice or a press. Two man job but it works. Had to do my old KDX220 when they collasped, and they were seized in solid. This was the only way we could get them to budge.
Plus its such a PITA job I would always put new one back in, complete with any new seals etc. On mine I had to replace the spacers and the shaft as well due to the wear.

got mine out by heating the swinger with a heat gun and using a long drift to punch them out. They were knackered though so I wasn't too concerned about damaging the bearings.
To get new ones back in, I used the swingarm pivot bolt and some cylindrical spacers that were the slightly bigger in diameter than the bearings. Place the pivot bolt nut on the other end (also with spacers) and wind both of them in with a ratchet. Use lots of grease though and a bit of heat (espescially to get it started).
maybe not the best way, but it worked for me

Stick new bearings in the freezer for a while, they'll go in a fraction easier.
I normally use a length of threaded rod with a plate on one end, and a socket about the same size as the bearing, large washer or two over that, nut on top, then ring spanner on that and wind it in.
Make sure you don't damage the place where the bearing will sit with a drift when removing them (not saying any more )
Can't remember if you can get generic bearings for the swingarm, but might be worth checking out with a decent bearings factor before paying for the same thing in a little kwak packet

Wouldn't try it that way, most swingarms have an internal stop (can't remember if the kr arm does or not, lost track now ) for the bearing to sit on , so you'll be messing for a long timeheadcoats wrote:Cheers for the replies
Just getting the first one out looks the biggest headache
Elf do you mean pushing the one all the way through with a bar as in say the right bearing would exit on the left
In extreme cases, where they've been rusted in , I've even used a dremmel with a slitting disc to cut the bearing before getting it out, hopefully yours shouldn't be as bad as that!

Dry ice in alcohol works well you can get them done to -50 quite easily .Red Devil 777 wrote:Stick new bearings in the freezer for a while, they'll go in a fraction easier.

Nope push the right one out of the right side and the left out of the left side. It'll depend on the design of the arm as to the best way to push them out.headcoats wrote: Elf do you mean pushing the one all the way through with a bar as in say the right bearing would exit on the left

Bearing is listed as bm283417 on the parts list (care of mj's website )
So I assume that to be 28mm bore, 34 mm outside diameter, 17mm width.
Quick search shows it's not a common size but there are some available.
Also smaller bearing on the linkage is definately available from non kwak sources cos I've had some.
