throttle shaft bushings

Paul and Dale did a great job developing an alternative method for replacing these bushings. I was going to use their method and ended up making a few changes. I ran this by Paul last evening and he suggested posting it.

When I have too much time I think too much. This is the result of my most recent free time. A take-off on the method that Paul and Dale came up with for replacement throttle bushings. This way the only thing I had to do under the dash was remove the cotter and put the shaft back in after grinding the hole. I am not saying this is better, only an alternative.

These are the parts I used, missing but included in the list are the flat and lock washers for the clamp bolt. I drilled the bushings and lock collar with a 25/64 drill. I also used a Dremmel tool to grind the bushing holes so the bushings would slip in.

For the washer on the passenger side I used a washer slightly smaller than the washer. I used a 1/4 inch washer drilled with a 25/64 drill and ground slightly to size. Picture is before altering the washer.

Then I slipped a bushing and lock collar on the shaft for the driver side. Notice this bushing is left the original length.

Next I slid the bushing and collar over and into the bushing hole on the drivers side.

Then I mounted the arm, washer, spring, washer, bushing, small diameter washer, and cotter. The cotter I crimped so it was inside the diameter of the washer. On this side I ground the bushing length to fit leaving about 3/16".

Then I slid the bushing into the passengers side.

Then, with the shaft against the passenger side I moved the locking collar and bushing against the drivers side and tightened the collar. Only thing left is to adjust the arm.

Anyone who doesn't replace their worn out throttle bushings now has no excuse. No more burned or stabbed fingers from trying to install those crappy OEM bushings.

Bit of work initially but a HUGE improvement 'down the road'.

The engine in and floppy bushings was always a PITA for me in the shop. Seemed every TR6 we ever saw needed the "treatment". The bushings I'd use were from "Special Interest Car Parts" and actually FIT, but that still meant a gymnastics workout to do the job.

If it were my car it'd get this 'conversion' just for DRILL! /bcforum/images/%%GRAEMLIN_URL%%/wink.gif

Tom,

The OEM bushings lasted how many years? 34-37? These are a far superior material than the originals, so I figure that you and I will be into our late 90's before they start to show any minor wear again. And at that point, we'll be getting driven around, so don't worry about it.

That means that someone will still be driving you around.

Get a bib early in case you start to drool. It comes from smelling grease and LBC's leaking oil.
