Engine/Transmission (1994 - 1998) Pump problems, truck is down for the count

[ChillyDog]

Hey all,



Yesterday I was on my way to Wyoming for a snowmobiling trip and the truck took a dump on me. We came to a stop sign and the truck died. I had a hard time getting it re-started and once running it would stay at around 1250 rpm. After a few calls to Aron Howlett (Amianthus on the TDR) and lots of choice words out in the cold, we found out that one of the spring packs for the GSK had somehow hit something, or something had come apart inside of the pump, leaving one of the studs/spring packs bent. I am at a total loss as to how any part of the governor could hit anything inside the pump? Both spring packs were still set flush with the stud just like I had them set on install. Another thing that has me confused is after I got the truck re-started the volt meter was showing a constant draw, almost like the grid heaters were stuck on? Anyways, I had the truck towed to a pump shop in Iowa and I am now wondering if it is worth it to dig into the damaged pump and repair it at unknown $$$? Or replace it with a bigger/better pump? I would love to have a PDR stupid pump, but $2800 is a little on the steep side right now, and the money I had planned for a turbo upgrade is going to have to go towards pump work now. I need to figure something out soon, my truck is almost 200 miles from home and I am supposed to be leaving on another trip next Wednesday night. Any ideas, tips or suggestion's would be greatly appreciated.



Thanks,

Bill

Sounds like something else gave away inside the pump. The govs just happen to take the hit.

John E is the expert on the P7100 pumps.

I would go with the a new pump. I have a funny feeling its gonna cost ya either way.

I've been there before. At 61000 my pump had a bad barrel. I did have to fight with the dealer. They did not wanna fix it under warrenty. To make a long story short. They did fix it under warrenty.

Jeff,



I also have the feeling that something else let loose inside the pump and ended up hitting the governor. That is my dilemma, do I spend the money to pull the pump and have it torn apart to see what's wrong, or do I just bite the bullet and get a HAPPY pump? I guess I am looking at worst case scenario's here, there were a lot of aluminum shavings in the oil when I checked the GSK, so I am fearing the worst. I am still at a loss as to why the truck was drawing juice while running?

Bill;



I remember this happening to another person not long ago. Something let go and it bent the stud holding the spring stack.

I cannot remember the cause or the repair cost.

Maybe he will read his thread before Monday so you have an idea what to expect.

edit

98rammer is the one that had a similar pump trouble. I believe his was caused by the governor lever pin dropping into the spinning mass. I think he bought a replacement pump from Joe D.



I would get an estimate to repair and call a few pump shops to see one has a used 215 hp pump to sell for a reasonable price. You're probably going to need a bigger turbo to handle a stupid pump. A Cummins reman is pretty reasonable if you catch them in a good mood, too.



I know Mike Adams has a couple pumps in his shop, but don't know if he will sell one. I'll email you his number and you can call an ask.



Jeff

I'm no pump expert. I just like working on them.

John,



I remember a thread not to long ago about bent GSK parts too. I am going to search that thread in the AM. The pump shop that I have the truck at in Iowa seems like a very good shop. I just don't want to spend the money to pull the pump and tear it apart just to see what's wrong, when I could possibly bolt on a 913 pump for close to the same price.

info

Back in 98 a remanned pump was around $2500.

My truck whens its really cold out will kick the grid heater on and off. At least under 5 belowand fully warmed up . Thats sitting and idling though. Once I get rolling again Every things normal again. You can find Bosch service centers through this link. http://www.boschservice.com

Bill, if you need a lift home give me a ring. I think I can get ahold of a trailer if need be as well. At least that way you don't have to pay labor to get the pump changed out.

What a bummer...

I would think even if you get a new pump (. . or rebuilt, or... ) your original pump should be worth something. It would sure be nice to find out what caused the failure.



***** always happens at the most in convient time.



Hope all works out well.



The Mike that JohnE spoke of does have a 215hp pump that is still probably on the engine they bought. He has plans on building a triple 12V pulling tractor so I am not sure what he will part with. I would check with him and other shops to get lots of options.

Josh, I made it home the following morning but the truck is still in Iowa, thanks for the offer though! I plan on calling around in the morning to see if I can pick up a 913 pump for a decent price. I would love to have a stupid pump from Piers, but $2800 is a little to steep right now, and I don't think my poor old HX-35 can handle anymore fuel than it gets now. That's what really sucks, the money I had saved for a new turbo has to go towards this now :{



Thanks for your help guys

 

[JoshPeters]

Well if you want to tow the truck back let me know. It sounds like it's not to far away, we could always make a red-eye run some night this week.

Well it turns out that I ended up with the exact same problem as 98rammer had with his pump a while ago, the governor lever adjusting screw fell into the pump and did pretty extensive damage in the governor area. I decided to order a new pump, and I got a great deal from Piers and Mark on a slightly massaged pump. I have this strange feeling that the HX-35 is not going to be very happy with me and the new fueling . Guess I should have asked santa for that new set of twins after all!

yeah, unfortunately john is right. i did the lever adjustment as per what piers' directions gave. however, i didn't tighten the nut just enough. after about 5,000 miles the nut, lock washer, and short screw work its way out. while on a back road i got on it hard only to let up with it idling really high (1500, then 1700). the 3 pieces went around with the governor assembly and bent one rod rendering that side useless.



yeah, the new governor assembly is about $800 alone... . though piers said he would send out a used one if he had it for free (awesome guy!). i just got the 370 marine injection pump off joe d. for a great price comparibly... plus i learned more from trying it out.

um... that rod doesn't look centered

 

[98rammer]

and i didn't buy these at a hardware store.



sorry to hear that Bill!

 

[midwestdually]

where at in iowa is/was the truck by chance?

 

[ChillyDog]

The truck is at Injection Technology Diesel Service in Northwood, Iowa.

 

[midwestdually]

ahhh Inject-Tech..... good people there... . best around here that i know of

 

[JJW_ND]

Any advice...

Bill or Tom:



Knowing lots of us adjust or will make adjustments to the govenor lever can you offer any advice to prevent this?



I asumme you adjusted yours???



So far I have not had to but I have helped a few friends install plates and GSKs and I would hate to make an adjustment that might lead to the failure you had on someone elses truck.

[98rammer]

installing the gsk is no big deal. it's the lever adjustment that i worry about. take your time, use a mirror to make sure everything is where it should be (probably the most important), and tighten the nut down real snug.



Tom

 

[ChillyDog]

I guess my advice is to double check the nut to make sure it is tight before you put the cover back on. Maybe a little lock-tite just to be extra sure?

I'm on my way out the door to Montana sledding. Hopefully the PowerStroke that is driving has better luck than my truck on the last trip.
