What to do about the 82GPz750's swing arm sleeve

[Guest]

Complete lack of maintenance for YEARS has left it DOA It's a piece of 22mmOD,16mmID tube.Found some out of England on eBay http://www.ebay.ca/itm/STEEL-PRECISI...sAAOxyRNJSciAk .The $5.41CAD price is good but the $22.52CAD shipping not so muchLooked a McMaster&Carr,the only metric tubing is SS and a 1" piece that size is $48USD +shipping. This kit http://www.ebay.ca/itm/271327524432?...%3AMEBIDX%3AIT out of Blighty is starting to look like the better way to go.

Can't a new one be purchased relatively reasonable?

On every fiche I checked it was NLADidn't do the whole list but enough to think it's just NLA

[Buffalo Bill]

I don't get the issue with using that? Is that just a spacer between the bearing sleeves?

Look at the pic,the grooves are where the bearings ride on the sleeve.If it was just a spacer it would be easy.

[Killer Canary]

You could fill the grooves with weld and then turn back down to size.
If you were anywhere near me I'd do it for ya.

You're both in Canada. How big could Canada be?

[hillsy]

Cut the sleeve in half, turn the pieces around and tack them back together.

Yeah - ghetto, but it should work.

[Buffalo Bill]

I dunno, the complete kit with bearings looks real good to me. The old roller bearings must be bad too.

Good point - the bearings will be shot as well as the sleeve.

[SVSooke]

Yeah one side had no needles left at all,just rust.The other was mostly rust with a few needles intactThanks for reminding me hillsy,while your idea of just cutting and welding wont work because the sleeve's pitted.I do have a piece the same size,I believe it was the swing arm pivot from the KDX. Why not just cut this,use it as a spacer and use the KDX piece cut in 2 for the bearing area.Was thinking I'd have them welded but thinking about it why bother?

[Road_Clam]

When I relube the s/a bearings in my motocross bikes I will mix about 80% Mobil 1 syn grease and 20% antisieze. Been doing this for the past 20 years of racing. The 80/20 mix makes for a super slick and moisture impervious lube that lasts a LONG time. I did this on both my GPz , and my GSXR. I also do this to the steering stem bearings. High pressure washers that many use for MX bikes are brutal on these bearings. New OEM Yamaha grease is the worst as far as quality. The OEM stuff looks and feels like 100 year old Vaseline crack jelly !

No need to weld them together, the bearings and spacer are separate in the GSX750F, I just changed out the swingarm on mine. In fact I was thinking the spacer could even be made of PVC, no stress on it at all.

Antiseize has metal bits in it. Adding that stuff to your grease is like adding grit. Where did you come up with this idea? Maybe I'm missing something but I've never heard of anyone, certainly no OEM, recommend mixing grease and antiseize.

Some common water proof grease is all you need. Marine grease as sold at auto part stores works well.

Oh and regarding that sleeve and the bearings, that kit from the UK would make life easier. It's a little expensive is all. You should be able to find a salvage sleeve out of some bike. There are scads of old swingarms laying around in salvage yards. The bearings are about $10 each from Kawasaki. Partzilla is my favorite parts source for Kawasaki parts since they have competitive pricing and a good fishe.
