Rear Beam Phosphor Bronze Bushes

[gti-si 0]

I think people trim it down Mei. I read a topic where someone doubled up the bearings removing the spacer completely and filled it with a foam of some kind to keep the grease on the loadpoints. Seemed a bit :S to me.

 

I could do with seing the spacer as well really, might be off to the scrappie ey!

 

Anyway, got all my costs sorted, group buy for the 205 bushes will be up as and when the moderators moderate it

Wouldn't something really cheap like fibre reinforced PTFE do the job perfectly well? It's such a low load on the bearings I reckon it should be fine...either way I'd need corner weights before I could figure out whether it will work.

 

I might look into getting a drum rear beam and doing some testing myself.

There's a huge load on the bearings - you've got a foot long arm for leverage on them, fibreglass filled PTFE, or even bronze-filled PTFE, has nowhere near the compressive strength needed, plus, it'll creep over time.

the saxo/106 has a pin that is the same diameter all the way along , on the inside of the radius arm is an inner and outer bearing , which have even narrower rollers than the 205/309 item , approx 9mm , so when i got my beam rebuilt last time , i had 2 pairs of 205 roller bearings fitted , this just needs the plastic spacer trimmed down a bit

 

as far as the saxo/106 radius arm goes , the inner could take a 29mm wide bush , but the outer only 22mm , although if the outer was longer it would still work ,just that the spacer might drop inside the radius arm and be tricky to fit , unless its glued in place first , so no big problem , i was just suggesting both the same length to make it simple , and hoped it would also be compatible with the 205/309

 

if you can get a better price than £35 then looks like i'll be buying from your group buy also , although for us saxo/106 owners , we would be requiring 4 outer bushes and no inners if they are designed for a 205/309

So the outer bushes would do both inner and outer on the saxo, but be limited to 22mm?

 

I can do 2 205 outer and then another 2 at 22mm wide instead of 25mm for the saxo/106 lads.

 

Can do 4 for £96

 

Group buy page hasn't gone up yet, unsure why, but hopefully it'll be there in the morning with all the info

25mm would be fine also , as the spacer could be held by the inner side with grease or something untill its slide onto the stub , as soon as its on the stub the spacer cant go anywhere

Sounds good, but don't forget to subtract half of the interference fit of the OD from the ID. When pushed into position the ID will become smaller.

Cheers Pete, I'll make sure I allow 50% of the tolerance for the ID
