Who has rebuilt their own pump and had good results. I have performed all my mods myself but have never been deep inside an injection pump before. On a scale of 1-10 how difficult is the job? I want to do a bunch of custom stuff and am not sure if I want a shop to be touching those kind of things.

 

I haven't had one apart, yet, but am gonna go into at least three pumps, as soon as it will quit pouring the rain every day.

I have been gathering links to various helpful articles on the VE pumps; you can find them here :

Down about post number-9 is a link to a DVD/book set that is worth every cent of the fifty-bucks I spent on it, although the VE he is demonstrating is for a 4-cylinder V-W, and has a much simpler top portion, the main pump and internals are the same as ours.

Surprisingly, and quite frustrating, is the lack of good pictorial information on our 6-cylinder turbo-equipped Dodge-specific pumps; nearly all the info I have found is on V-W sites.


Someone needs to do an in-depth article on re-sealing a Dodge/Cummins VE-pump, starting with removing the pump from the engine, complete dis-assembly, cleaning, re-sealing, re-assembly, and re-installation on the engine.

The V-W information is really helpful, but there is a ton of difference in the upper additions to the pumps.

 

In my view, there is rebuilding, and re-sealing/modifying.

I have disassembled and put new seals in two pumps so far. Both have been in daily service ever since -- over a year now. If you are clean, careful (don't drop or lose anything) and methodical (remember to make notes and draw diagrams -- like how the internal shut off lever is clocked, and how many turns the governor shaft was threaded in) it is not too hard.

If you get in there, though, and find that you need a new bushing for the input shaft, then you have to get a bushing (supposedly not available from Bosch anymore) press the old out, press the new in, and ream to fit your shaft. If you have a good machine shop at your disposal, that is doable -- but if you are doing it at home, it would be hard to get good results. Also, if you start swapping parts, you won't be able to get back any real fuel settings without a flow bench. If you just want to turn it up as high as you can, it isn't a problem, but it if you want more control in your tweaks, it gets a little difficult.

I strongly recommend reading the VE manual and understanding the theory of operation, looking at the VE diagram that Jim Lane originally posted when he put new o-rings in his case pressure control valve, and making sure that you have a Bosch seal kit before you start.

 

its easy to rebiuld but dialing in is the had part expecialy with out a flow bench, my first one took me 2.5 hours and some coffee

 

bump....anyone else?

 

To say it is easy is a loose cannon statement. Arm yourself with all the material you can find, the Technical Instruction, the umpteen bazillion posts, the part breakdown schematics and the latest $50 two hour long VE rebuild dvd. Then it would be somewhat easier. And keep in mind that many a fool has gotten away with completely disassembling one and had it work in the end...

 

here are some pics of mine putting new seals in it is not to bad if you take your time and are very clean.
