I'm looking for a set of good bushes that go inside the needle rollers on the swinging spindle of my '83 GPZ1100A1 uni

They look like this when they're fucked



From memory I think the ID is 15mm OD is 25 and length 37 . I'd spin some up on the lathe but they're hardened and ground

Mine were similarly shot, tried every where no longer available from Kawasaki, got them made in stainless steel and bought needle rollers from simplybearings.co.uk with genuine seals (still available) works a treat. The dimensions are on the cmnsl website

if these are what the bearing runs on they need to have a hardened surface I doubt stainless will last that long. HRC 58-64

Depends on how much lube and how few miles you do!

You need lube but it won't help with the load. Yep if you dont ride it it will never break

I can easily spin some up in stainless, but as Jon rightly points out, they need to be hardened.

My reasoning is I will be lucky to do 1000 miles on it each year, if it wears out in that time I sort out another one. It's got a bolt running through it so I can't believe it will snap so the only issue is reduced lifespan. Seeing as Kawasaki probably had to over engineer them incase of neglect (which they all were - so finding a good second hand one is unlikely) a reduced spec item that keeps the bike on the road has to be a sensible option - doesn't it? Or am I risking a catastrophic suspension failure?
Either way, if you find a way of making some hardened steel items perhaps you could make me some too - I would need both smaller diameter spacers, the big one is in good shape.
Good luck

Fork rechrome specialists will be able to sort them surely?

Luckily I have managed to source one from Cradley and one is OK so I'm sorted for the time being

by the way the technical term for f&*ked is false brunelling caused by small movements back & forth that removes the lube & wears the surface. Just being a smart arse

I know and understand the cause and result of this phenomena, though I didn't know the technical term to which you refer, but can assure you that all engineers, regardless of professional speciality, will be fully conversant with the term 'fucked'. I therefore would humbly suggest that when conveying the overall condition of a part, my use of the vernacular, is probably better use of the language, particularly as the Z1OC is unlikely to have a second member with any knowledge or understanding of the term 'false brunelling', whereas I bet close to 100% know what I mean when I say 'it's fucked'

Yeah - I speak smart arse too

Yep f*cked works as does googling the term to find the correct spelling
False_brinelling

That makes sense - it may derive from the dents made by the Brinell hardness testing method?
