The Stovebolt Site Forums The Shop Area Engine Shop Throttle linkage stud

Can anyone confirm that the threaded hole where the throttle linkage stud screws in the block is 5/16-18? This is in my '55 235. I need to fab up a replacement and don't want to take the time to pull it out just to check the thread since it's my daily driver. I figure someone on here should know.

Yes, 5/16-18 thread.

Thanks Denny, I knew someone would know. I'm looking through the album you posted, I like the drawing of the stud. TooMany2count was nice enough to offer me a used one by PM.

Thanks to TooMany2count, who mailed me a stud, I was able to rebuild my throttle linkages on Saturday. His showed up Friday in the mail. Saturday morning I went to town with the new stud in hand to find a clip for it. The one on my truck never had a clip which I think lead to some of my problems. Here's what my stud looked like when I removed it.
Old Stud

I found that a 3/8 e-clip fits perfectly on the new stud. I also found a 3/8 id bronze bushing that I thought I might use on it as well. The holes in my bell crank were oblong and oversized already so I drill them out to 1/2" to fit the bronze bushing.

You can also see that I welded some washers on both sides of the arms of the bell crank. Those holes were oblong as well. The 1/4" rods were worn so they got a little weld and then ground back down to round.

Once installed I added a few washers to take up the space you can see here.

Everything moves smoothly now. If I do anything else it may be to make new linkage rods using heim joints.

glad to help you out & that it worked for you....joe

Looks good! Where did you get the bronze bushing?

The bronze bushing came from Ace hardware. It's 3/8 ID, 1/2" OD, didn't measure the shoulder or length.

Good Job Chad, very professional looking. Should serve you till
they won't issue you a licence any more or till we run out of
crude for gasoline.

Denny, that's was my intention. I wanted to fix it so it wouldn't wear out again. That's why I may go back with heim joint ends on new rods.

Sweet fix! Much easier than my fix which involved a short pipe tig welded in where your bushing is. Looks to me that you could have re-used your old stud with that fix, since the bushing won't ride on the bad spot anymore. But then, I am a tight wad. Now all you need to do is add a grease fitting and you will be good until the solar-powered hover crafts come out.

Me too, in the past if I couldn't find one I would have brazed it up & filed it down to fit the bushing...joe

I didn't even consider that I could have used the old one. I was looking to use a shoulder bolt until I was offered that good one.

If I were you, I would save the old one. You never know... I usually put parts like that in a place that I know I will find it in the future, and then never see it again. Don't put it there.

I've got a plastic storage tub with everything I've pulled off that may be use-able. That old stud is going in there. Hopefully I'll remember I have it if I need it.

I have about four different sizes/colors of those plastic tubs, dating back to around 1969. You will soon forget what you put in those bins/tubs, but it is comforting having them AND you sometimes find something useful (even if the use is not the original use).
