That?s because the white nylon bushes got painted cadmium with the rest of the 
mounts.  It clearly looked like Eric had spread the mounts to insert the 
bushings, then re-crimped them to hold them tightly in place.

... and another on the gas pedal shaft--4 total--although that one doesn't 
suffer as much abuse (that was the 'under the dash' part).  Can't speak to your 
car, Bruce; the instructions show these are suitable for BN7s.  Maybe prior to 
BJ8s they used something different (can't imagine cork would hold up long at 
all).  Mine were rubber/bronze bushings in a metal cup; the nylon/teflon ones 
still go inside the metal cup.   Looking at Bruce's photo, you can see the ends 
of the cup protruding from either side of the brackets, although I don't see 
any of the white nylon bushes.

Every time I think I've done every possible job on a Healey it proves me wrong.

ps.  Of course, it's Eric GruNden, not Gruden.  Guess I still had a little 
football in my head.

engine is out these need to be replaced, two on the cross shaft and one where 
the pedal shaft enters the engine bay.

Nice photo.... looks just like my car

I was going to replace the bushes on my throttle shaft, but saw what Eric had 
done back in, well, who knows when, and they looked great.  So I just stripped 
and painted the shaft.

Good catch. They tend to get munged when folks install or remove their engines, 
if not as stated heat and time.

I built a cable throttle set up to bypass the Rube Goldberg set up. I have 
promised a wrote up to John Sims for quite some time to add to his wonderful 
site. I have been slowly working on it and will soon I hope get it to him.

Cross-posting from BCF:

 

While getting ready to drop the rebuilt engine into my BJ8, I noticed the 
'throttle relay shaft'--yeah, the one under the scuttle, all but impossible to 
get to with the engine installed--was bent. 'Crap,' I thought, 'one more job to 
do before I can get the engine in.' It turns out this was serendipitous--first 
time this word's been used on the List?--because as I inspected the shaft, I 
noticed that one of the two brackets was also bent, and further inspection 
revealed that the bush on the driver's side was way sloppy (actually, pretty 
much gone). A quick check of the Moss catalog showed 'N/A' for all the 
parts--I'm screwed, I thought. Then, I remembered I'd bought a replacement 
set--supposedly made of teflon, but they say 'nylon' on the bag--but had given 
up on installing them because the instructions showed 'through BN7 and BT7' 
(BJ7/8s need not apply). I called BCS to see what they had, and John, their 
parts guy said they'd work on BJ8s. So, I did some digging and, although the 
photo of the instructions and applications on Moss' web page showed 'though BN7 
and BT7,' if you download the instructions--5 pages!--they've been revised to 
show they work on the 'J' cars.

 

Anyway, if anyone has the engine out of one of the later 6-cyl cars I recommend 
you check these brackets and bushings. They are bronze bonded to rubber and, 
although my car has nearly 200K miles, I suspect the life of these is 
determined as much/more in years as in miles, as the rubber gets baked by 
engine heat. The rubber on my driver's side bush was completely dry, caked and 
brittle, and could conceivably have resulted in a stuck throttle. The 
instructions are intimidating--5 pages!--but, except for having to work under 
the dash, which I hate, the job was pretty straightforward. I managed to get 
the shaft reasonably straight, and the used bracket I got from BCS was in good 
shape (though, in hindsight, I probably could have straightened my bent one), 
so now my Rube Goldberg-designed throttle works smooth and with no slop.

 

Thought I'd pass this along since I hadn't seen this issue discussed before. 
I'd long since replaced the rubber/bronze bush on the shaft on the engine, and 
should never have to worry about these again. Credit to to Eric Gruden who 
designed these bushes, and to Moss for going the extra mile to provide these, 
for a reasonable cost (about $13).
