Anybody devised an elegant solution to fitting the needle rollers easily :?: obviously a press is the way to go but have no access.
Have a few ideas around threaded rod with turned bushes anythin simpler before I start

thanks boys

I turned up a couple of bits of ally and used an M10 rod to pull them in. I'd post a pic
but that'd mean going out in the snow to the toy cupboard :)

If you're really stuck, I could lend you the ally bits via post as they're fairly small
and M10 threaded bar is pretty easy to get hold of.

I just purchased a couple of plate washers and a threaded bar from a builders merchants. Cost about 3 pounds and job done.

I used the threaded rod and two end plate method. The pack of threaded rod I bought from screwfix made 5 seperate presses and I sold them on ebay for 3 to 5 pound each. Thinking of approaching Dragon's Den.

Last bearing almost in.
Not sure if your bearings finish flush or recessed, but if recessed you might have to find a suitable socket or thick washer.

Thanks for all the ideas lads I have aquired some m16 threaded bar nuts and washers from my tame engineering co in high wycombe one last question did we all put two bearings in each side as per parts diagram blowup or is it just overkill

I can only speak for my Z650, which has 2 each side. If Kawasaki designed it to have 2 in, I would definately put 2 back in. You are far better having the forces spread between 4 than 2, they would wear out too quickly. I have just had a quick look online at a parts catalogue and the 1979 KZ1000 have 2 each side, you did not say what bike you are fitting them to.

Another thing I did was to heat the swingarm in wify's oven about 100 for 10 mins(don't get it too hot, just warm) and I had the bearings in the freezer for a couple of hours and greased the outside of the bearings lightly.

All sorted now lets hope fitting the arm to the Mk2 was as easy as fitting the bearings :lol:
