The Stovebolt Site Forums The Shop Area Engine Shop Throttle Return Spring Question

Does anyone know how the throttle return spring clip connects to the engine rail. Do they just snap on and stay or do they have an oil pan bolt go through them. Here is a link http://www.pbase.com/dennygraham/image/139631246 - I'm talking about the where the bottom of the spring connects to the block. Also where might I find one of these critters? Thanks.

What year truck?
What size engine?

Some years/engines use the clip shown by Denny.

1941-1953 216/261 - clip shown by Denny
spring used with clip shown above

1950 216. That may work. Does an oil pan bolt go through it for hookup?

I just made a clip for my 50 coupe Saturday. Yes, a pan bolt goes through it.

Note: someone will have to verify this..................the throttle spring I used was TWO springs wound together. I suspect that is a safety thing but I do not know if they were double when original. I just happen to have one from a ????? car I worked on one time. Ace Hardware is a good place to "rummage" through their supply until you find what you want....and cheap with no shipping.

Alvin,

Quite often, after an original spring got loose, and stretched, and abused, and maybe replaced by whatever spring was on-hand - one spring was often not enough. All sorts of solutions were employed.

I have a spring collection from 1960s-70s junk yards.

Tim, I wish I had a picture handy. They are identical and one would over look it if you weren't careful. It was definitely made this way....but no documentation of what it may have been made for. I liked it so it is now on the coupe.

.....yes, like you, I have seen some almost un-believable set ups......which means I'm getting old...uh, older! hehe

In some years of 235 engines, that tab was used with a return-spring.
In some years of 235 engines, a return-spring was attached to a hole/recess in the block/pan "rail".
In some years of 235 engines, a return-spring was attached to the brass block-coolant fitting near the middle rear of the block.
(some GM illustrations were provided not long ago in a similar discussion here)

here is a listing of different accelerator pull-back spring lengths, and clips

I think the truck suppliers sell that clip. The clip is held on by a pan bolt. It has a small ridge in it to fit over the lip of the pan. It is tear drop shaped and the small end has a hole for the spring.

Photos of the clip are shown in the second post.

Thanks all!

Interesting that they had ........."free length....two Loop ends" and "free length....two Hook ends" and other configurations as well. Just shows that one size don't fit all as we all well know.

Thanks for the links Tim, you have taught us one thing for sure........ documentation is the key!

Pictures of springs/locations would be nice, too . . . (worth a thousand words) . . .
