Started the 3 up on Saturday and drove on down the road after sitting since January and noticed the gas pedal moving kind of strange and making a funny noise. After 48 years the gas pedal throttle shaft bearing on the driver side finally disintegrated.

I tried to order just the two bearings last night only to find out there is a minimum $10.00 order requirement after it spat my $9.90 order back at me several times. So....I decided to go to on-line ordering heaven ordering one of these and one of those while gleefully hitting that add to shopping cart button.

Well guess what's back-ordered today?


The bearings! /bcforum/images/%%GRAEMLIN_URL%%/cryin.gif


Now I'm thinking of just pulling that outer bearing cover and cutting a piece of my wifes dining room chair anti floor scuff plastic thing-a-ma-bob in half and jamming it in there to create some type of temporary plastic bushing. Think she will notice the difference?
 
everyone is allowed one chicken-poop solution ...

(should I have put that in quotes?)

There's a brass bushing replacement that you can get for pennies but it may take me a bit to find where I last saw it.

The TR6 guys developed it.
 
"anti floor scuff plastic thing-a-ma-bob"

Drill out the center to the shaft diameter,
file the outside to match your existing bushing
holes and shave the length to about 1/4" and it
might just work.

I'd give it a go.

Dale,

Let's do this right. You did the tutorial, so now point to it. You are the "Grand Master of Bushings" you know.....
 
I plead stupidity, Paul.

How would I direct someone to the tech piece
we authored on throttle bushings?

Harry,

If it's the accelerator rod bushing 330-560 that you need, I think I have a couple in my shop stock for my 4A. I will check stock in a few minutes.

Is that what you need?

I can mail them in the a.m. after I get my wife back from her chemo session. Probably arrive in Conn. by Thursday at the latest.

See if you guys can post it in the "Knowledge Base" section of the BCF. Help Basil build it up a bit. /bcforum/images/%%GRAEMLIN_URL%%/thumbsup.gif
 
Yep. I have a set from TRF p/n 58282 T24 Bush, Accel.,Nylon

Email your address to me kentech0822 AT verizon DOT net and I'll drop them off at the Post Office in the am.


Just ask that you replace them when yours come in.
 
Dale it's in the post that I linked to above for Harry. Read down to your replies and bookmark the page for future reference.

Shawn, I will get this into the knowledge base by the weekend.
 
Paul,

Just so you know, TR2-4A use a different accelerator arrangement including totally different bushings. Harry has a TR3 (in his signature) not a TR6.

Now develop a home-made bush for the TR2-4's and we're all set.
 
Peter,

Oops!! I apologize. Someone told me once that the bushings and throttle setup were almost all the same. My bad!
 
Well ... maybe almost but look way different from your pics.

Like a rounded cylinder, not slotted like the TR6:

Thanks All,

Peter, I'll e-mail you the address this afternoon when I get home, Thanks! Wife thanks you too. One chair leg was almost a half inch lower than the rest last night

Paul, When I did a search on this there are pages and pages and pages of TR6 throttle bush repair suggestions. Sounds like not so much fun judging by the comments. Had to get back to 2005 to read about Alan's fix which is applicable to the 3.
 
PeterK,

Can you post a photo in profile?

And photo of the throttle shaft in the firewall
with a bushing present...

I'll betcha I can design a non-miserable install
replacement.

I'd go take a look at a TR3 myself and figure it out
but we have that problem of "there ain't none"
here on the island.

This mght not be much help,but,years ago I replaced my bushings in my TR3 with ball bearings, wow, almost felt German. Sorry, I dont remember the #s, but take your bushing cap and your throttle rod to your local Detroit Ball Bearing store and find the one that fits. Cant remember exactly what I did but am sure it was'nt hard. Actually,..I cant remember what I had for dinner last nite.
 
If you look in the McMaster Carr website, you will find flanged or non flanged bushings of all sizes made just as you need them for a few bucks each. Use the same method of install as Dale posted and you'll be good to go.
 
Thanks Paul,

I'll put that .pdf in my ever expanding TR6 file!

That looks like a real slick fix. It looks like it would also probably work for a 3 as well.

We have these nifty little 2-piece bearing holder plates which are cupped to fit the bearing and screw right into the side of the firewall to hold the bearing in place. They are pretty visable and definitely noticable if they are missing. We also have three roll pins that hold the throttle shaft together. I'm sure by now that's not all that's holding it together.

Depending on the direction of the jet stream and given the velocity of the speed of sound... Thanks to Peter you should hear me screaming in Rhode Island about 11:00 A.M. on Saturday. I just hope it's not during your backswing.
