Engine/Transmission (1998.5 - 2002) Help, questions on reman. VP44

[Phil Stuart]

I just got a reman. VP44 (IPVR-44/17X) on Monday and want to get the truck running , and was scoping it out real close before I go and install it and noticed the keyway on the reman pump is an 030 (the old one a 028). The reman pump has numbers stamped on the top boss area close to the front that are 036. Whats the deal here?I read in the FSM that the keyway MUST mach the numbers on the pump. Do I disregard this and just put it in? These stamped in numbers are not in the same location as the ones on the bad pump. This reman pump just has a small plate with serial number and model of pump with BOSCH on it and thats it. The question here is do I or don't I have the correct keyway for this pump. I hear that the pumps are updated with new parts and some electronics, Yes? So maybe someone can shed some light on this cause I shure as heck don't want to have it all back together and then throw codes again and run like crap.

Have any others encountered this same thing?

Help, want to get it back together soon, I will call this morning to the place I bought it from to see if there is anyone that knows the answer to this.



Thanks,

FWIW I called this morning and talked with the mechanic about the pump keyway. He said that the pump is test run with an 036 keyway and the 030 key will work without any problems.



It's raining here and truck is outside so probably won't get to work on it today. :{ I would like some more input from those of you who have noticed the same thing I did on a replacement pump, any thoughts or comments bring it on.

Phil,

I'm not an expert by any means, but I'm guessing if the pump was "test run" with a 036 and test run means "set-up during bench testing" then shouldn't it have a 036 in it. But, like I said I'm no expert, maybe during bench testing/test run it was determined to need the 030 based on "test" results. I'm "assuming" the outfit that rebuilt the VP is certified Bosch and knows what they're doing . . . Without asking the name of the shop I'd try to call another "certified" re-builder or maybe even Cummins?

Hopefully someone that has had the same situation, or one of the TDR Members that are vendors will chime in with more specific answers for you.

Joe,

Weather broke, put pump in this afternoon, no problems with install.

Fired it up, ran fine once all the air bled out. Drove up to Advance Auto Parts to have the codes cleared. He got rid of the P0216 code but not the P1693. Did he miss that or will that one just go away after so many starts/key cycles? Everything seems OK. Some guy there offered me $22,000 for the truck and said it's NOT for sale. Joe, U know where I bought it from, I'm happy with their service and will ship the core out tomorrow.

Call Central Motive Power in Denver CO ((303) 428-3611). Bosch reman facility.

The keyway is the timing adjustment for the pump, and the pump electronics should be calibrated for the keyway. IIRC Not bench tested with one and another installed.

I will call them today.

Maybe the stamped in number on the pump has no relevance whatsoever. I suppose they'll tell me. Truck runs good tho, put pedal to the floor and has good acceleration, no miss, fuel press no lower than 11 or 10 tops on hard run thanks to FASS I put on a while back. No more crappy Carters for me.



It is a dumb question but what does IIRC mean? I'm not really good at texting, go ahead and laugh

I called Central Motive Power,

The technician said Yes the pump is calibrated for a specific keyway number.

The number that is stamped on the top boss area may just be an old number corresponding to the key it had before it was remanufactured. That makes sense. He said too if the engine runs fine with the 030 key, then there shouldn't be anny issues with it. I would have thought if it was the wrong key that it would have already set off another DTC. That hasn't happened so far.



Thanks for the tip!

Phil,

DTC's can be set and stored in either the ECM (Cummins computer) or the PCM (Chrysler computer). He probably only checked and cleared one of these and inadvertently left a DTC set in the other... hence the P1693 DTC which indicates a code was found set in the other computer.

Bottom line: If it's running good and the MIL (check engine lamp) isn't on, then there's nothing to worry about. The P1693 should eventually go away after enough "good trips" (start / run / warmup cycles). If it doesn't, you can investigate further later.

Thanks JLandry,



Yeah, it runs great Glad I was able to do the job myself. Figured I saved a ton of money that way and learned about the truck in the process.



It's all a learning experience.

Try un hooking the BATT'S for 10min then rehook up start truck and then check to see if the code is there. === Good Luck
