HELP! Issues using Ichiba spacers

[11B-33T]

Need assistance with removing a broken hub-centric ring that has broken off and is damn near form fitted or crushed to the hub. I was removing my RH's and putting the MX-5 rims back on after having them balanced. This is what I found:

spacer on hub with broken ring

destroyed old ring

lower half of ring stuck on hub

new complete ring


Has anyone ever had this problem using Ichiba spacers? More important, how do I get the broken ring off? Any help is greatly appreciated!!

It looks like you're going to need a chisel and a hammer, is that the only one that's like that? It looks like the spacer wasn't right for that wheel hub.

This is the only spacer set that had a problem. The other three are GTG and I pulled them off to inspect for cracks/splits etc. These are the spacers Ichiba recommend for MSPs: MZ-52110, 10mm, pattern 5x114.3, center 67, thread 12.1.5

Thanks Thad. Took your advice and gently split the ring using a hammer & chisel. Replaced the ring and torqued all lug nuts to +85lbs. I'm still unsure what may have caused this...

That is extremely unusual, did it seem like it was pretty stuck on the hub? Maybe it was a combination of stress from heat, and exposure to the elements that made that one fail. Perhaps it was just a weak one..... they make a product for aluminum to steel applications (I can't recall the name, its a product sold for BMW's by Bavarian autosports) that is ssuspect, to prevent aluminum from adhering to the hubs of wheels. You might try to find that product on their web site, if that could be the suspect.
Edit: that just has to be a really strange failure on that hubcentric ring,

I had the Ichiba spacers too, and have a suspicion as to why the problem occurred. The rings are actually a tad too deep. In order to get the wheels to fit flush I was gonna have to torque the wheels down to the point where it was likely to crush the ring against the hub... sort of like press-fitting a bearing. I ended up grinding the rings down about 2mm so the wheels would seat to the hubs without forcing them against the rings. If I hadn't done that I think I might have had the same scenario that you had.

I checked the other three spacers & they're fine so why just this one hub? It's the drivers side rear BTW.

Maybe just variations in tolerances, either in the rings or the hubs, or the wheels, or a combination of them.
