Easy idle adjustment.
Easy idle adjustment.
Here are some pics of the idle adjustment that I put on my truck to make doing adjustments possible without a lot of cuss words.If you have any questions, ask away.



Some of the pics are real close-up so you could see exactly where things went. I have my stock adjuster backed all the way out, and just use this one.

On an automatic - 650 in Drive with the A/C on.
Stick is supposed to be 700 with the A/C on, but they idle much smoother at 800, so that's where I like them. You can't do that on an automatic because it pulls too hard.

In the second picture, what is the large bolt/nut that is vertical and (I think) is through the throttle-lever ??
Also, why the screen-door spring, instead of the normal one; is it required for this idle-adjust modification ??
One minor detail that I would suggest :
I assume the steel is also tapped/threaded.
I would insert the bolt in the opposite direction, such that the head of the bolt rides against the throttle, with the locking-nut moved to the forward side.
This wouldn't in any way change the function, but would give a larger bearing surface, thus less wear on the throttle, and less chance that it could ride over the bolt.
Good job.
Thanks.

My Idle screw is broken. (What happens when you let your dealer install a recall pump). The throttle lever on the pump is held back by the threaded rod with the two ball joints. If one of the ends fall off of the ball joints, the truck will shut off. lol
After looking over your design I just wondered about using one of the old high idle solenoids from the late 60s and early 70s gas burners. I don't remember for sure what they were call but they came on with the key so that the Indians would idle properly and then shut off and not diesel when you turned off the key.
Thanks for the pix and info. I just did the same thing and thought I'd post some other pictures of it. I just moved my return spring over one bolt on the timing cover. It doesn't bind up at all so I think it'll work well. Thanks for posting this modification!!
