throttle body bushing
phil - July 17th, 2005 at 09:25 PM

dual solex carbies (kadron kit)i have a bit of play in the throttle body shaft area, they need bushes fitted to take up the wear,
any of you guys had the same problem? who do you get to fix them? any idea how much it is likely to cost?
an aquaintance tells me i need to install sintered bronze bushes. has offered to help, he comes from an engeneering background
and has heaps of gear, lathes etc
what do you think?

your friend is right about the bush

IF your friend knows what he is doing then go with him

Otherwise Carburettor Service Company on Parramatta Road Burwood NSW does this work

thanks again bizarre......i'm confident he can do the work...i guess i wasn't sure about s/bronze versus what other "experts" recommend

Hey, Ive got a bit of play in the throttle shafts aswell i think, not heaps but we are going to rebush them one day. At the same time probably give the whole carb a clean up. My dentist who is into vw's told me all about it and said the hardest part was drilling out the carb bodies that have been worn. Let us know how you go.... very intrested.

From shoptalkforums.com:

"For Kadrons-AJ Simms rebushes throttle plates with nylon bushings that lasts longer than brass and costs about the same as new throttle plates which are now available seperate from Empi."

Do not use sintered bronze - its used for bushes with an oil feed. Besides in this situation it would be to brittle.
Use brass.
You will find the original bushes will pull out. These can be replaced by someone with the expertise (your friend?)
but they will need to be "reamed" to get final internal diameter to suit the butterfly shaft.

hmmm....thanks for the feedback fellas, but i am still confused, my friend says sintered bronze , AJ Simms...says nylon, many others say brass...the s/b is oil impregnated so as to lubicate..says it wont wear out, the nylon "last longer than brass", brass is what is used originally??? like going to the doctor..need another opinion...

sintered bronze is hardy ill give it that im using a bush made of it in my flywheel cause im still waiting for mike sharp to send me the bush for my t4 its been in there for about 18 months now and ill be looking at it when i pull the motor down to fix the oil leaks

whatever you end up making them out of make up two sets while your going, that way next time its a piece of cake, out with the old and in with the new.
