Title: Throttle bushings
Post by: Merv on April 06, 2020, 01:25:26 PM
I want to replace the bushings on the throttle arm under the hood. Can this be done on an S1 GTV without removing the engine??

Mere,
Are you talking about the 2 'd' shaped ones attached to the firewall that hold the
Accelerator rod?

I did mine recently but had the carbies off at the time and it was a little fiddly.

I'd reckon with everything in situ the inner one will be the hardest bit.

That's without looking at the car, I'll go check tomorrow and see ...

Cheers.

Easy job. With the air cleaner off and the right spanners it's not too hard with everything in situ.

Thanks for this.  I replaced the ones on the horizontal shaft easily with everything in place.  However, the one with the ball joint for the throttle shaft is the problem.  I believe it needs the carbies' removed from the rubber gasket/manifold first as the old metal cased bushing will need to be cut out and the new one pressed in (on the bench)?

Not as bad as I thought.  Removed the airbox and carbies and then pulled off the bell crank and the throttle rod. Removed the 'coil for clearance and then was able to remove whole accelerator pedal assembly easily.  On the bench, the rubber in metal encased bush in there was disintegrated and causing so much slop.  I drilled it out and pressed in the new bushing.  The bell crank was also sloppy so it go some treatment with new washers, pins, copper grease and a little tightening of the shaft pivot point on bracket.  Now as smooth as ...

The whole job was really quite straight forward.  I would 'hate' to replace that bush without removing the accelerator arm and pedal.  Serious respect for those who managed that.
