Idle adjust?

[DPKetchum]

Ok. Went to adjust idle speed up a little/dropped after new injectors. HOW THE HECK to you get to the nut to break it loose to adjust idle speed. What size is the can't get to nut!Shop manual said use suitable tool. YEA RIGHT!Give me some hints guys. Oo.

That thing is in a sweet spot eh? To do mine I used a punch with a nice sharp edge to knock the nut loose. It only takes a little tap, as the nut isn't on there really tight. Use punch to tap the nut tight again. There is also a thread on this in which someone posted pics of a universal joint and a crows foot 10mm used to reach the nut.

I'll give it a try. Hope its not tight. Why can't simple things remain simple!Thanks for quick reply!

If it was easy anybody could do it I have a special wrench from snap-on that does the trick. If the punch trick does not work I will scan it and send it. The wrench is at work right now so I can get the info tomorrow.

I just adjusted mine tonight. I use a 1/4 drive 10MM socket,u-joint,6" extension and ratchet. Luckily mine wasn't too tight.

Well the punch hasn't worked so far. How deep of 10mm socket does it take. Mine has a bunch of screw sticking out past nut.

The only reason I've never used the punch/chisel method is if it doesn't work, then you've got a nashed up nut and it's hard to get a socket on it.

The 10mm deep I use is about 2" long. I usually put one of those nut driver adapter things into the socket (1/4") and a small wrench to turn the adapter.

The adapter is used to put a socket on a screwdriver. It's about 1 1/2" long.

I should take a picture of the setup I use. We see this question in here alot.....

You'll also need a little stubby screwdriver. Mine is about 3 - 3 1/2" long.

Hmmmm... I must have an oddball truck - not because mine was easy to adjust, but it sounds like more of a pain than the others. Besides the major PITA to get to the nut (I tried a normal 10mm wrench and a 10mm ignition wrench but neither would work, so the punch did the trick), there was a fuel line (?) directly in line with the screw - not only did it prevent using a socket but I also couldn't get a screwdriver on it. I managed to get it set up some but what a pain... .



It was well worth the $30-something I paid to have it "profesionally" done (not to mention I don't have a tach... . ).

I can get to mine ok with a screwdriver and i can get a 10mm wrench on the nut. Just no room to turn nut. Idle speed changes on these with outside temp. Was a warm day yesterday and was towing a horse and running ac. Idle was kinda low where in cold of winter it was ok. Thought i would just bump it up a little!Maybe it's me but i can't find any shops in the Athens Georgia area(HOME OF GA. BULLDOGS)that will work on this or know much of anything about these trucks. Had to go 60 miles just to get front springs rebuilt and a alignment. The nearby dealer dosen't even have any shop manuals on pre 1994. Said they wern't open then! If any body knows of a decent shop in this area let me know. I bet it will cost me almost that to go buy a 10mm deep well socket and swivel. Before i replaced injectors it was almost too high but i like a little high instead of low.

The punch worked on mine. My friend who just got a 1st gen bought the Snap-on wrench and said it didn't work, so I told him to try the punch method. I use a blunt punch instead of a sharp one so it doesn't tear up the nut. Luckily, mine wasn't overtightened. The hard part for me was turning the idle screw once the nut was loose. If I remember right, I used a 6mm ignition wrench.

I've made a special tool for this job. Take a 10mm boxed end wrench, bend, weld the boxed end at 90 deg to the handle and weld a hex on the end or a handle for turning. Make it 2. 5" to 3" long. As soon as the batteries in my camera get charged I'll post some pictures.

Do it right and make the tool, it's not that hard.

I have BORROWED a 10mm deep well and swivel. Had a 1/4 drive ratchet etc. Will try again on Saturday. NOW JUST A THOUGHT GUYS all the tools etc. are great BUT i was looking at the metal tang that the idle screw rides on. THE part it moves in or out to adjust idle. Kinda thought about drilling a hole through it,tapping it for a small screw and just running a screw in it only from backside to adjust idle??Be easy enough to adjust just like old time gasser carb.

 

[DPKetchum]

WELL FORMULA you were correct. I could'nt get a swivel and deep socket on it either. Try again but instead of a punch used a small chisel. Once it came loose the nut turned very easily. The adjust screw did not want to turn but finally it did. Adjusted idle hot,ac on until transfer case shifter and mirrors were smooth. The idle screw is still stiff to turn. I left lock nut loose for now. Can't Imagen it over turning on its on no matter how much vibration. What a poor design.

 

[formula]

I'd bet that the screw will turn much easier if you move the throttle lever off of it (open the throttle a bit). Mine was this way. Although, the paint on the screw can make it difficult to turn.



Cheers,

I think it was the paint. Also reason lock screw so hard. I still think if needed could drill and tap and add a screw from back side of the lever plate.
