For my 94 IDI turbo the IP should be the DB2-5069. The pump that's on it says DB2-4823. It also says RM2 on it and its a Stanadyne pump. The tag on it is silver instead of read or black. I googled Db2-4823 and the only reference I saw was for a 1988 Ford. Where the heck did this pump come from?

 

I found this on J&H Diesel Service Website: DB2831-4823 04823 1813460C92 7.3 Liter 1990-92 Navistar S Series Truck (170 HP)

This is the IP that it is on my truck. Apparently at some point in time somebody has replaced the original pump with this one. I don't know what a 1990-92 Navistar S Series Truck is but I know it ain't my 94 IDI turbo!

I was originally hoping to just get by with replacing my injectors but so much for that! Will be ordering the correct one tomorrow!

 

edit,
oh yeah,i misread what you said you have.my bad.
yup.i guess someone just wanted to get by.

off topic fyi,
i thinks Dave's info may have these reversed:
DB2-5013 - 1992-1994 manual tranny
DB2-5028 - 1992 -1994 auto tranny
but i doubt that matters much.i dunno.a stock looking 5013 came off my n/a auto truck is all.plus a little brief search showed someone saying the 5013 was the auto.are the same exact pump,or would they make one with a different timing curve for each trans....danged if i know,but i doubt a guy could ever tell the difference if so lol.

so you found the DB 2831 is a 1990-92 N/A pump then.
well,good to know at least.
there was high and low altitude pumps too i think i recall researching Dave's posts.can't recall any of those part numbers though.

Ken over at DPS says this too,for more info worth knowing:
Turbo Calibration - As the name implies, only good if the engine has either a factory or aftermarket turbocharger. We readjust the fueling and timing curve to take full advantage of a turbo, and normally raise the governed RPM to 3800. The max fuel delivery capability of the pump is also raised. Although we can do a turn-up on any rotary pump, the ideal pump to use is a "XX31" model, found in the '93 - '94.5 idi. We can bring an "XX29" pump up to the same fuel delivery, but the price will go up due to the extra machining involved. Maximum gains are seen when a matched set of injectors are used.

I think when you posted that list for me, I didn't know what I had. I was going by what the PO told me when he said he didn't think it had ever been changed. I guess he didn't know what the owner before him did. I looked at the IP this morning and inspected the tag on it and knew something wasn't right. Don't know why I hadn't already done that. Oh well, my injectors won't be here until monday anyway.

 

this is why once i experienced the stalling issue i had after quick deceleration and hit up U-Haul at the time for a set of reman Delhi's,i just decided to grab one of their pumps a little later too.
iv always just done a complete tune up when buying a used vehicle.just because like you say,until you do it,you just don't know the condition of the ware items.with today's fuel prices,it just doesn't pay to mess around.

 

I just dread timing it, from what I read in eaton's thread it sounds like a bear! I don't know of any shops around here that could time it other than maybe the Ford dealership and I'm not 100% sure they can!

 

don't let his results scare you.
he has something seriously wrong going on there.
pretty much everyone who's recently been doing thier tuneups have all been happy with the performance and FE increases.
they are pretty simple to tune.timing isn't all that hard by ear/feel,it just takes some time.as you can see,he was very scared to make it rattle without the timing meter.don't blame him,but they gotta sound like a diesels a little bit.
you will want it properly timed for best results for sure though.

 

I'm gonna give it my best shot as soon as my pump and injectors get here! I was talking about this topic today and was told by someone that being out of time can bend the push rods. I said well I don't have an answer for that so I just wan't to make sure that won't be an issue once I get it close and until I can get it somewhere to fine tune it.

 

just follow the directions as shown here,and you wont mess with the valve timing.
this NEVER gets altered.there is only one setup for this.you will be steering clear.
TikiWiki : IDI Fuel Injection Servicing

as you can see,only the access cover will be removed.you simply remove the ip from this,via small bolts leaving the valve timing unaltered.


once the ip is back installed and everything buttoned up.you just be loosening the 3 larger nuts on the ip that bolt that on (the ones that are pain to get to.without a modified wrench.) and you'll be turning that to adjust just the ignition timing.this tells the ip when to send the fuel in to burn.too early or two late can both lead to bad things,so care must be taken as well though.


in the event you make a boo boo lol (you wont if you just follow that article)
for the love of god,don't start the engine.cus if she did take off,there could be valve clearance issues.
just follow this first:
http://www.members.shaw.ca/k2pilot/Timing%20article.htm

 

Okay, I've saved that fuel injection servicing article to my favorites and have read it about a thousand times now and plan on having it laying beside me when get started on this.

 

Setting the timing wasn't the hard part. Figuring out why my truck isn't running right is the hard part. If you follow that tikiwiki article, you should be fine. I have typical bad luck when doing work like this and it usually turns out to be some unrelated component failing at the exact same time and causing me tons of extra work and grief. I have the worst luck some times.

 

eaton if you think you have bad luck when it comes to working on cars, you should hear the story of my $300 oil change!

On another note, my injectors came in today but they were B codes instead of G codes like I told them I wanted. I told them I wanted Stanadyne injectors and even gave them the Stanadyne part number but oh well! My mom is the office manager for the parts store/machine shop that I had order them for me. They don't deal with alot of diesel parts, except for BIG Komatsu stuff so even at her price they were a couple more dollars each than I found other places. Ended up having to have them order the IP too since they were the only ones that would except my core since it isn't the proper IP for my truck and I wouldn't be able to send in a turbo IP for a core. All of the other places I tried said they'd have to charge me the core charge unless I had a DB2-5069 core to send in. So I can promise you that my luck is no better than yours! LOL

 

Hey 250, got a question. When I get my new pump I'm sure I will want to turn it up a flat or two. Can I do this before I install it since it would be so much easier or do I need to install it at the factory setting for timing?

 

you really shouldn't alter it at all without a pyro.
since the ip's fuel settings and each truck is different,it's really best to adjust it in the truck imho.
i say this,because too much fuel can lead to high exhaust temps and melt pistons.
someone can get a rebuilt ip from the same place,both trucks may have turbo's and seem the same,yet one guy may need to stay where it is or up just a flat,the other may need two and half flats.

 

I've got a pyro/boost/trans temp installed but I can see your point about installing it first and see where its at before altering it. I was just thinking about how much easier it would be to do it before hand.
