I know but my luck something would go WWEEEEEEEEEEEE across the yard and never be seen again. I just hear so many " I messed with my pump and now it doesn't run " . I like all the " outside the pump " screws and afc stuff but internal,,,,, Im not there yet.

 

i was very hesitant to install mine. however, i need to reseal the AFC pin so the pump top was coming off. i figured, why not do the 366 spring while it's off instead of pulling it off a 2nd time. it's actually much easier than i had initially anticipated. as long as you index the throttle shaft correctly and install the fuel screw exactly where it was, you won't have any problems. oh, just don't drop that top hat!

 

Ive been following this from the start!! Glad you got it running!! I have to do mine as soon as I have my back up vehicle back. And Richie O, I was a newbie and the first mod I really made was that spring... It is totally worth it!!! Wont drive another one a week without it!! Too bad you arent close to colorado, Id help you do it for value meal and a coke!!!

 

O, I will do it some day. I just like all the harrasment I get.

 

I must be lucky. Gov spring was the first thing I did to my truck a few weeks after I got it, before I even realized there was no "g" in Cummins.

 

For any one that reseals the pump & it doesn't start right away don't spray it with either I did this once & the fuel collar wasn't lined up with the pin that goes into it Well it started but it ran away & froze up the head & broke the shaft. Expensive lesson

 

Or look at it this way, for anyone that reseals a pump, does a governor spring install, does any fuel screw adjustment, you should have the air intake tube off the turbo with a 'choke off' plate or board ready to snuff out the turbo in the event of engine run away after start up.

 

↑ ↑ ↑ ↑ x2!! i was told to have a stiff board to choke the turbo with after installing my 366 spring. it didn't run away, but i had someone holding the board ready to choke it if the RPM's were to rise on their own.

 

I had a board ready to go the entire time. I learned a lot about the VE pumps and what can go wrong throughout the rebuild.

If anyone is around NC and needs help with one, let me know. I can pull them pretty easily now and don't mind helping fellow DTR guys out

 

when you spray it with either you don't have time by yourself to get the board over the turbo by the time i positioned the board up to the turbo it was all over

 

So I started toying with fuel screw settings. After turning up the fuel and adjusting the idle, it idles great. There is around 1/2" of screw sticking out after the locknut.

When giving it throttle, it starts to go up and sort of stumbles. I know it has to do with the fuel screw setting because before I turned it up it drove fine but didn't have as much power as before since I set the fuel screw somewhat conservative after resealing the pump.

Any ideas guys?

 

Stumble is usually due to the throttle lever indexed too loose.

 

I had adjusted the lever because it was idling too high, but returned it to what was stock. I can adjust it down another notch and see I guess.

 

I just bought a 93 for my son and the pump leaks on it. All I can say is that it is great to have a bunch of guys like you all around to learn this from. I was really upset about the pump leak until lurking around on the 1st gen forum.

Many thanks for you sharing your knowledge

 

ok, the pump is still leaking . I pulled the rotor head two days ago and put a brand new seal on it. It's dripping off of the rear support bracket.

Using a light and mirror it looks like it might be coming from the nut/bolt in the middle of the injector lines. I blew the pump off with compressed air and after starting the truck I can see fuel/liquid right below the very middle small bolt. Is there an o-ring behind that bolt or do I just need to tighten it down. I didn't touch that at all when I took the pump apart.
