correction rulon 142 is closer to turcite B and is even the same color.

Ihave used turcite  a or b ,  a is blue,   X is red and b  used to be an auqua color  B is the hardest and best for high loads  as it has much higher content of fillers usually bronze and others  Turcite A  is  similar to Rulon 142

Are you using Turcite A (Blue) or Turcite X (red)?

> Tried poly bushings in this 911 application, did not work well still had
the same problem as the rubber , on street door bangers the turcite bearing
feels as solid as an aluminum bearing from a responce stand point but has
none of the bad clunky noises and are maintainence free . next they never
wear out aluminum and poly or delrin all wear out or become brittle /cold
flow . The turcite in a couple of cars I have have been in them ( lower
control arm bushings) for over 15 years and they are like new.

in a similar application from a buddy of mine at nasa in the bay area. they
used it in bearing/bushings for space applications, I used it for tooling
and bed ways ,

my race cars and the rest is history . I replaced all the rubber or aluminum
with either heims or with turcite a, or b depending on location , the
turcite absorbes vibration and does not squeek in the places I have used it.

Delrin. Anyway, the Turcite B material is used by Porsche and you recommend
it. Wow, who knew about the secret life of bushing technology?! Thanks for
the short course on high tech plastics.

> Turcite is a composite material used to line and repair bed ways on
machine tools like mills. The concept came up when trying to get bushings
that would locate the control arm as well as be self lubricating , allows a
press fit and will not bind in an application on a Porsche 911 rear trailing
arm. The rear arm has this huge rubber bushing that gets compressed in the
rear control arm attachment bracket and acts as both the bearing and locater
for the trailing arm as well as has to take the load from the torsion spring
that all 911 cars (air cooled) have . The use of aluminum caused binding ,
delrin cold flows too much and the bushing/bearing goes out of whack in very
few runs , , tried lots of other materials and then did a lot of research I
had turcite b and c rods in my shop for use as self lubricating busings in
tooling so tried it and it was better than any thing else from a wear ,
stability , press filt with no cold flow and is compatable with

> Next it can be machined to tight tolerances and for the 911 trailing arm
joint that has complex motion it worked , I use turcite extensively in any
door slammer car when I want good bushings that work as well as all metal
but need no lubrication.

it---finally (duh). It does seem to be quite a formidable plastic. The only
downside seems to be some real deterioration to acids and to chlorine (salt
on the roads?---something that is possible,but *extremely* unlikely with a
Pantera). I recall that the specs seemed to say that it was *harder* than
nylon. It also did *not* say anything about my fuzzy recollection of "cold
flow" deformation. Also, just as Mark says, it can be *machined* to exactly
what (offset) you would like. Pretty cool stuff.

poly but also don't need to be lubed. Dick made several changes to
suspension at the same time so you may want to talk to Dick or others doing
the same thing. All I can say is the bushings he installed look new as the
day he put them on 7-8 years ago.
