The sleeves are not meant to turn inside the swing arm, it should remain stationary, thus the need to press them in with the bolt /washer/nut tool. This sleeve is in essence the outer race of the bearing set-up The needle bearings rotate on the sleeve on the O.D. side and on the bolt that goes thru the frame/swing arm itself. On the I.D. side.In essence the Inner race That is the way i have always seen needle bearings operate

One more thing. On the diagram it shows bushings on the swing arm but I had only bearings. Can I use either or with this swing arm? It's the 1978 kz650b to be precise.

I also noticed when I had the sleeve and the bearings inside and decided to put it on the bike when I put the bolt through the swing arm and tightened it, it was hard to move the swing arm up and down. But when I loosened it it was a little easier.

But if you are actually having to hammer the sleeve in then something is wrong wrt the size of the bearings. Or they got ruined while installing them. having to do it a second time would really suck.
That sucks,...I know how frustrated you must be, I spent all day getting the old ones out. I actually used the swing are bolt to try to get the old ones out and deformed the end so much that I had to get a new one, So,...I am good a breaking things also.
I used a threaded bolt, washers, and nuts (and socket for the deep ones) to pull the new bearings in versus using a hammer to make sure I did not deform them.
Yeah I didn't check them on the sleeve before installing them. I assumed they would fit. I forgot that the sleeve was supposed to go in easily. I bought these bearings off Amazon because they were the same size. The need height is too high or whatever. I'm really not sure the purpose of the bearings honestly. I didn't wanna get the bearings off z1 enterprises for $11 each. No thanks. I'm gonna just have to somehow get these bearings out now.
Well for some reason these bearings aren't allowing the sleeve to turn inside the swing arm

Probably because the old ones were worn out.blink543 wrote:JimB wrote: I wrote grinded but I actually just used some sand paper. I do not think some rust would make it that hard to get in. Take a good look and make sure some bearings did not pop out and are stopping the sleeve from going it. Just for the heck of it did you try to turn the sleeve around and/or push it in the other end of the swing arm first?
Yes I did but upon looking at the old bearings vs the new. They are both the same size but the new ones have a different needle height compared to the old so that must be the problem. Wtf why can't needle bearings just be the same
Back when these bikes were fairly new/low mileage it would of been no big deal to just change out the bearings and reusing the sock sleeve.
But now that a lot of these bikes have lots of hard miles on them and many of them went for years without seeing a grease its really important to inspect everything.
Another thing I always suggest on these old bikes that have been used and abused is to have a machine shop line hone the pivot opening on the swingarm to make sure its straight,Especially if going from bushings or single needle bearings to double needle bearings on each side.

Safe riding.
But is the sleeve supposed to be so snug in the bearings that it doesn't move?

I got the older bearings in and I slid the sleeve 3/4 of the way in but kinda got stuck on the other bearings so I had to wack it in pretty hard to get it the rest of the way through.
Zephyr 750 front hub width, any owners? was created by scubaanders

Any Zephyr 750 owner on the forum with a ruler/caliper?
Currently upgrading my KZ750R1 with parts salvaged from old Zephyr 750, like the swingarm and the front fork. But I am going for ZXR 400 wheels and I found my self running in to some snags fitting the front wheel.
There fore I am trying to figure out the width of the front hub of original Zephyr 750 wheels.
Does anybody feel like giving me a measure?
Its basically the measurement between the two front brake discs.
I tried the Zephyr Zone forum, but obviously the guys on that forum don't own any Zephyrs as nobody could help me out :blink:
