Cush Drive Bushes

Okay good UKMOC folk just a quickie question for you....

What sort of age/mileage are people replacing the Cush Drive Bushes on your Monsters?

Mr Gazza · 16-05-2018, 08:05 PM

Not yet at 34000, but I have got some visible radial play on the sprocket, so maybe I will soon need pins and bushes?

Yes I've got a little play that sounds slightly metallic more like pin wear rather than cushioned movement if that makes sense?

So would change both while I'm doing it.

Mr Gazza · 16-05-2018, 08:32 PM

Yep. Same here. A metallic click when I jiggle the sprocket. So the pins are probably no longer a good fit in the bush's metal sleeves.
I'd be happy just changing the pins if that did the trick as I've heard that the bushes can be little scallywags to get out!!

Yes have seen they can be a nuisance to remove but surely the rubber will have hardened over the years and therefore will not really be cushioning anymore so just replacing the pins will exaggerate the harshness?

That's probably a good point, but I can't think that having the play in the metal parts is a good thing? Hard rubber or not.

The real McCoy would be polyurethane bushes if they do those bobbins in that material.
It's so much better that the "Rubber"! that is used in bushes of that kind.
I put Powerflex Polyurethane anti roll bar bushes in my Alfa and they made a great handling car even better...

I so need another Alfa..
