Big problem with governer install

[sparks57]

Ok, so I installed this 3200rpm governer spring, but I have spent all day and up to about 3am last night intalling and trouble shooting.



Well, the truck is not in running condition.



Every time the truck is started, it starts to rev up... faster and faster and it doesn't stop until I shut the key off, and then it dies right away.



Along with this, is a lot of white smoke and a lot of missing... but I attribute that to the fact that the engine was cold... my engine always misses and smokes when you give it a lot of throttle right after startup. I could be wrong though...



The ball on the control collar is in tact, the start spring behind the start lever is fine... I have no clue what is going on here... I've been poking and prodding away at the pump for hours and talking back and forth with Dave Miller and Mike Dorsey, he's even got some big pump shop stumped with it...



So does anyone have any ideas what is going on here?

 

[RGT]

are you certain you got the throttleshaft and lever aligned right when you put it back togethor? I had just the opposite problem when I put mine back togethor, I had put it togethor off one tooth... . is it possible to have the foot that the spring attaches to pointed the wrong direction?

 

[sparks57]

Well, I have tried to run it with the throttle shaft in all different positions, and I've had the fuel screw out past stock... so those are not the source.



As for the arm inside the pump, I positioned a mirror so that I could see everything inside as I was puting the top back on the pump... everything went together fine. The throttle moves fine.



I primed the pump and cracked all the injector lines. Fuel flowed freely from all 6.



I'm going nuts trying to figure this out.

C_B,



Have you gone thru the governor spring install instructions I posted on this topic, and if so, did you stick with them pretty much as layed out????



Next, have you looked at the sequence of pictures I posted as a reference??

http://turbodieselregister.com/foru...eadid=88027&highlight=governor+spring+install



Just to be sure you've covered the most common things.....



>The index mark on the throttle shaft has a notch on the top end. That notch should line up with the "10:00/4:00" index marks on the throttle plate.



>Have you made sure that the little spring/top hat/cup washer are in the correct position?? They should be on the outboard side of the start lever...



>Are you sure that when you install the lower spring cup/spring/upper spring cup/throttle plate/hex cap screw that the index marks are exactly right on the proper index marks... . only one "tooth" off will cause your problem.



>Did you fully remove the full fuel screw from the pump, then re-install to it's approx. original position.



>As another member asked... . are you certain that the throttle lever w/spring anchor is in the correct position... . the spring anchor and gov spring end should be moved towards the engine on re-install.



Fill in some of this and we can try to go from there... .

Me thinks someone is going to need to go back in and find out what got messed up. Enough of these have been done that we know the procedure works if done properly.



My suggestion since you say everything was put back together correctly, put the pride aside and take the top off and find out what went wrong. :{

I have taken the pump off 5 times now looking for what is going on. I've called Dave Miller 5 times, Mike Dorsey 2 times, and Mike even called Seattle Injection and nobody can figure it out.



The only suggestions were that the start spring was misplaced, the control collar ball was broken, and that the return plunger spring had failed.



None of those has happened.



As for the teeth on the index, uh... I didn't realize it was that important, but I have it right at, or real close to where it was.



So one tooth off can cause all this? Aw crap man. . this is gonna really take a long time if I have to go back and find the exact position of the throttle shaft again...



But bob, I did follow your instructions exactly. And I did every one of those things you listed, minus the index maybe.

C_B,



This item can and has caused the condition you are seeing... I don't know if it is the cause in your case, but nascar mark did some experimenting around this area and reported similar symptoms as I recall.



It won't take but 10 minutes to check this one out.

Just remove the 8mm allen cap screw, lift it out, gently press down on the throttle shaft... then rotate it counter clock-wise a bit. When you feel resistance, screw the cap screw on a couple turns, lift upward on it to pull the shaft up, remove the screw, replace the next few parts and re-install the cap screw.



That process will confirm your positioning of the throttle shaft/indexing (you're going to look at those marks while the cap screw is off, and while your rotating the throttle shaft. )

I don't think there is ANY possibility of having a cam/roller ring return spring fail from doing a basic gov. spring install.

If a spring(s) fail it was going to happen without the gov spring install.

In addition, I don't think runaway would be the result of a spring failure either... although I am open to correction here...



The components like the tensioning lever, tendioning lever stop, starting lever, starting spring, control collar, fulcrum etc are pretty sturdy bits... they are not easy to damage if even a tad of care is used when the gov spring is replaced. You'd have to have a fatally flawed component in place AND you'd need to disturb it significantly before they would fail from your gov spring install process.



Something is not in place here to cause the runaway condition you are seeing.



Let me sleep on this and I'll give it some thought ... .

I'll redo the shaft in the morning... I tried calling you earlier but I didn't realize Piers closed his doors at 5pm... the time difference got me!

CB-

I've been in your shoes, though not due to a GSK update. It was more trying to figure out why the thing wouldnt flow fuel to the injectors. Anyway, I'd bet a case of beer (You have to pay me then I buy it) and half a sorority house that you got the throttle shaft indexed wrong, or didnt put it back just exactly as it had been, either out of haste, or excitement and wanting to try it out five minutes ago. If you dont know to look at where it is in realtion to the rest of the stuff, it is easy to make this mistake.



I'm not sure exactly how i figured it out- it's been a year and a half, and a lot has happened since then. I know that Bob's idea was a little different from how I did it. Seems like I turned the shaft, minus the allen screwed nut, until I had some reisitance, (as the good Pastor suggested), then referenced where it was in relation to a line going parallel to the length of the truck (or the plunger/ shaft of the pump). That made it easier to get the hex cap on, and not have to worry about getting it exactly lined up with the rest of it. Back out your low idle screw as far as you can, then do the tension/resistance/referrencing thing. Then you dont have to worry as much about getting it all in and dealing with the opposing tension of two different springs (inside the pump- new GSK- and the throttle bracket assembly on top outside the pump).



Yes, one or two teeth off will make it rev up (or down). It may not be a runaway, per se, but it seems like it when you are expecting 700 RPM and get say, 1700..... Sorry for wandering, but I have been up since 6 and it is now 11:25... ... .



Later.

[sparks57]

Well guys, I've been fiddling with the throttle shaft for over an hour, to no avail.



When I turn it counter clockwise, it appears that the truck revs faster, and when I turn it clockwise... the engine just pauses before it revs.



Any ideas?

 

[sparks57]

I just put it back together, and now it won't even start. I put the old governer spring back in to see if it would work...



Plus, the throttle shaft broke off at the bottom of where the 8mm nut goes on.



I wasn't even tightening it hard... taking it on and off must have fatigued it. So I'm going to have to find a new one. Mike said he might have one...

 

[cerberusiam]

Ouch! You have my heartfelt sympathy. I have some spare pieces I think will work if you need then overnighted. Let me know.

 

[sparks57]

I went into town and got a metric nut to attach the throttle linkeage back on. I'm going to need a new throttle shaft assembly.



This is turning into a nightmare. Something is seriously wrong here. I think the governer in my pump is not working properly. The pump has 213k on it, with no rebuild... so I wouldn't be surprized.



I'm going to re-attach the linkeage and crack all the injector lines to see if this is just an air problem...



And if the truck starts and runs fine with the old governer spring, that means something is wrong with the governer it'self.



I hope Piers can cut me a break if I need a rebuilt pump... I've got $30 to my name right now. There aren't any local pump shops.

 

[dpuckett]

Sounds like you are in a real fix. Wish this wasnt over the interent- ONE of us could get it running for you. Dont feel too bad about having $30 to your name right now; I have $40. Send me a list of parts you need (or pics), and I'll see what I can do for parts from the Bosch shop in Sikeston. Paying for them would be the lone problem (though I should qualify for frequent shopper points), as I have "bills" coming up (aka Nazi extorsion payment), or I'd let ya reimburse me when you could. Lemme think a while.

[sparks57]

Well, I went to the hardware store and got a couple of nuts, and niether one fits. They are the correct diameter, but the thread doesn't fit. I have "normal" and "fine" neither one threads on the shaft like it should.



Just call me Mr. Murphy's Law.

 

[Stomp]

Hey don't let it get you down it happens to every one I really don't know, but it could be metric not standard or left hand threaded just some ideas hope you get it fixed real soon. I've done allot of work myself, but sometimes it pays in the long run to have someone else do it. I usually cause more problems when I get done working on something.

C_B... . you need to chill a bit...

Take a step back and cool off will you..... I'd really appreciate it if you'd keep the cussin out of the picture.

I hate having to edit anyone's posts... . unfortunately, I did have to make some adjustments to a couple of your's. .

Try to work with me here will ya. .



Bob.

 

[sparks57]

Sorry pastor... this is just very frustrating for me because I've been communicating back and forth with Dave Miller and Mike Dorsey, and Mike even called Seattle Injection and nobody can figure out what is going wrong here. I apologize.



Well, I re-installed the original governer spring, and now the truck is not running. I jury-rigged the throttle linkeage so the shaft would at least be at the index mark.



The truck would not start, so I cracked all the banjos untill fuel flowed out of them, and put everything back together. And it still won't run. I was very carefull when puting it back together so I know everything is in proper order.



I'm going insane.

 

[sparks57]

PB: I went back and smoothed out all my posts... sorry again, my temper got the better of me.

 

[BushWakr - RIP]

Don't sweat it C_B,,,, last time I check the only perfect man on the planet died 2000 years ago... . ...



Your problems are strange though... the gov spring change should not have cause any of your problems... Short of dropping parts/dirt/tools/and other crapOla in there any way.



Come on guys... jump in here and maybe we can help out one of the flock... he's already tried some of the more colorfull expletives and they aren't working... .

I must admit that if between Mike, Dave, injection shop, and us guys here you must have a significant problem that was just waiting to happen.

Are you certain the fuel solenoid is working? Have you tried taking it out, removing the guts, and re-installing it then try starting the truck?? Some times when you go into/near runaway the fuel solenoid can calf on you... . mine did...



Still thinking on this one .....
