Rib On 309 Arb With Power Flex Bushes

[shooter mcgavin 37]

Trying to fit powerflex bushes to my 309 front arb but there's no cut out in the bush for the raised/ribbed section on the left side.

Should the bush sit right on the raised section and just bolt the sucker down or do I have to modify the bush?

 

Just don't fit well at all

Send the bush back as not fit for purpose as it should have a groove, or modify it.

This is the issue with Powerflex bushes - they all have that. Send it back for a refund if you can find some that have the recess. Alternative is to just cut some clearance in there or bolt it up and ignore it might make it all a bit 'stiff' then though, so I prefer to take a bit of material out of the bush.

Think I'll just take a bit out of the bush, ordered them ages ago.

What's the rasied section actually for? Is it to stop the bar sliding side to side, don't think I see it on the 205 arb

205 arb has it unless its a base model with the locating bar and clamp.

I assume it's for that, yes... provide a little bit of side-to-side location.

Never noticed it, the bushes are still on that's why.

 

Looks like I'm missing 2 bolts for the brackets too. Can't even rob them from the 1.6 looks like it has a different set up .

its the same setup, but there's two types used, one cast alloy clamp with a bolt, and the plate steel with studs, its just a 30mm long M10 bolt.

Bolt it up and ignore it isn't good, as the bush grips the bar so tight that you get massive roll stiffness! I packed the clamps off the subframe sufficiently to give rotary movement of the bar but still supporting it properly.

Sorry that's what I meant the 205 one I have has studs the the 309 one has bolts.

 

30mm m10 any weird pinch on the threads? I'm done buying nuts and bolts from the dealer, spent a fortune already.

[welshpug 1,655]

they'll be 60p or so from a dealer, normal 1.5 pitch.

[shooter mcgavin 37]

My dealer stocks just about nothing. Everything I've bought so far has been bags of 5 or 10.

What I'm meant to do with 10 offset washers :-( the stuff to do the beam has cost me a small fortune and I still need 2 shafts yet.

 

Think ill try the hardware place, I'm not buying 10 when I only need 2.

 

Has anyone got a photo of a modified powerflex bush?
