governer spring install

Postby odee » Sun Jul 10, 2016 6:49 am

got the 3200 gov spring in yesterday. Had to work on getting it back running, bleed injectors. Once running let off throttle engine dies, turned idle up one turn so it would idle. Had 6 thread showing before now have eight. Did I get the indexing off on throttle lever? If so will it hurt anything?

I think that spring is slightly longer than the stock one. The only thing it could hurt is you might no get quite full throttle travel like you could before. If you want then you can trim it to stock length

The 366 spring is the same length as the stock one. It's only the 3800, and 4200 springs that are longer than the stock one. Like mentioned if you get the indexing wrong you may not get full travel meaning it won't do the rpm the spring is rated for.

I had assumed all aftermarket springs were longer since some are. I guess I was wrong

The 366 is the same or a very close to stock length. The 374 and 354 are longer and need to be trimmed or have the throttle indexed more to run.

I've done a few of them and sometimes the lever needs to be indexed 1 notch more because it wouldn't idle. I think it's because the spring is stronger it pulls the lever back to defuel more.

Also if you pulled the power screw out you might not have gotten it in the same place as before. If you didn't get it in the same spot and its backed out more the idle will be down.

What would you fellows recommend to try first? Thinking about giving fuel screw a half turn and back idle screw out some. thanks for the input.

Did you pull the fuel screw completely out?? if so are you sure you got it back in to where it was? Where was it set before? stock or turned up?? I think I would double check the throttle indexing and then if that still looks like goods turn the pump up. Some may give me grief but I turned my idle screw all the way in and then adjusted the idle with the fuel screw lol.

I bet you just need to run the fuel screw in a turn or what ever gets it to where it needs to be, I think the indexing will be a bigger swing than a 2 thread difference.

I moved the lever on my pump at least 7 times before I finally called it good. If I move it one notch tighter I cannot get the idle down, on the "right" notch the screw "looks" too far out by the witness lines in the grease. I didn't count threads or measure the marks, but fuel screw is cranked to the collar same as before I started so that has not changed

My idle screw is backed almost all the way out. My pump is turned up a few turns lol. I lost count. Did you go with the 3200 spring??

Yes, I went with the 3200 spring. Had a fuel leak and you need to remove that spring to replace that seal, so yeah. The pump was already "turnt up" with a ground fuel pin and some other stuff before I touched it, none of that was changed. Tailpipe test says the new spring is fueling harder, don't need an egt gauge to know that black cloud in your mirror is telling you to back down the smoke screw a turn or three

I've changed gov springs twice now, and neither time has the truck actually fuelled harder after. It's only fuelled to higher rpm.
