The Stovebolt Site Forums The Shop Area Engine Shop Photo of 235 throttle linkage & spring?

Does anyone have or can point me to a photo of the stock '55-'59 235 throttle linkage and return spring? My freshly rebuilt '55 235 is almost ready to install in my 1940 GMC, but I'm having difficulty figuring out how to hook up the spring. I'm using the forward most bellcrank pivot hole, the one directly behind the exhaust manifold outlet. I've cut and re-welded the bellcrank so it will work with the stock '40 accelerator rod. I've read in the archives that the spring goes from a clip on the vertical linkage rod to the lip of the oil pan. But it seems that if I run the spring straight down to the pan lip, it will interfere with the exhaust pipe.

A photo would be a big help.

Thanks,
Steve

I can hook you up with pics from a 235 in a '46 and a '50 if that will help.

If somebody hasn't beat me to it by tomorrow morning (little too dark to take pics now) i'll post 'em.

No pics, but I made a clip out of .040 aluminum sheet that nests inside the oil pan flange, then sticks out with a hole for the spring to connect to. Just hooking it over the flange didn't last for too long until I lost the spring. Also, some blocks have a small hole for the spring.

Both the 235 engines in the '46 2 ton and the '50 2 ton have the same deal.. the spring goes right down to the lip of the oil pan.

Not sure how the exhaust is routed in the later trucks, but in the '46 and '50 trucks, the exhaust curves out and away.

Thanks for the pic. That set up would be fine on mine if the exhaust manifold pointed straight down like your picture shows. But my 235 manifold exits pointing somwhat rearward, not straight down. It results in the exhaust pipe aiming right over where your spring connects. That's what is causing my confusion. There is no hole in the block to attach a spring that I can find. I can make a clip to go onto an oil pan screw if I can figure out where to put it so the spring doesn't get in the way of the exhaust pipe. I don't know, maybe it will work in that position of the exhaust pipe is made to angle out away from the block a little. The motor is still on the stand. I plan to have the exhaust custom made once the motor is in.

Here's mine on a '61 261. I had to mess around a bit with various parts and I don't know if the lever on the pivot on the block is stock 261.

contact me off line please

My 62 has a threaded plug that will drain the block. It is located at the back of the block down low, just ahead of the bell housing. I take it off when I flush the block about every 5 years. The spring attaches to this. I don't know if that's the same as 55. Good Luck!

I finally got the linkage worked out. By cutting and welding the bellcrank I was able to get the angles to match the bellcrank of the old motor. I welded at tab on the side of the throttle rod to attach the spring, then made a clip to anchor spring above the pan. Seems to work great and I won't need to modify the accelerator rod.

Take a look at my webshots page, in the 224 to 235 album to see photos of the motor and the modified linkage.

Thanks for the help guys.
