Suspension bushings

PostPost by: Elan45 » Mon Nov 07, 2005 1:11 pm

Bill,
I made bushings for my 20/22 out of Acetron, a lubricant filled brand name of a material similar to Delrin. They've worked quite well. I also made steel sleeves to fit over the bolts so the bushes pivot on them rather than the bolts themselves. The bolts lock the steel sleeves in place and the Acetraon bushes are pressed into the wishbones. I'm not so sure I'd want these on a street car though, as my Elan gives way more feedback then needed on truck worn freeways.

Roger


Is Delron a feasible material in this application???

Cheers,
Bill Tebbutt

Thanks for the info in your two posts. I had wondered about
dimensional tolerance of plastics that were machined. The idea
above, while great technically, is not legal for the SCCA Solo2 ASP
class as the proportion of metal to non-metal in the "replacement"
bushing is supposed to remain the same as "stock." However, I have
never heard of anyone being forced to take apart a bushing for this
measurement.

Regards,

I have a set of four of these, as I recall, (but maybe 8) that came
with some Europa control arms I picked up. I'm guessing the bushes are
the same for the Elan. Not sure what they're made of but it's off-
white like Nylon, and they are offset. If you're interested, I'll take
some pics and measurements for you. They're hat-style and unused.

If nobody's interested, just how do you make sure the offset winds up
in the right place? I never figured this out. It seems to me they
would tend to migrate after installation. They're a tight, but I'd say
short of a press fit. It also seems it would be difficult to get them
in the right place when installing.

I set the offset by calculation and Loctite stud or bearing lock will keep
them in place, yes even the Teflon ones hold okay with it.
