I took the 180 pump from my '98 to a pump shop for a tuneup and when they benched it they found the plungers were bleeding down bad. Upon disassembly found the pump was well worn out. . .excessive wear pretty much everywhere. This is on a truck that has been near stock power all its 208,000 miles of life.

I was quoted $2300 parts + $880 labor to repair. . .6 new plungers & barrels, governor components (they are badly worn), and the two main bearings. Needless to say I don't want to throw $3200 at a pump job!

I should find a good used pump but then what if might need rebuilding too? I basically want a good stock replacement not a hotrod pump. If I buy a pump from a vendor would they take a pump as a core that's essentially shot?

I'm surprised it turned out to be this bad especially since the truck ran very smooth, it's just that it hazed bad even with stock injectors & plate. It's basically done it as long as I've had the truck (for 80k miles) so the only thing I'm thinking is the last owner ran some bad fuel through it (he was not a "diesel" guy and pretty clueless about diesels in general).

Anyway any suggestions would greatly be appreciated . . .

For what its worth, u can get a reman unit from standard motor corp, or a1 cardone for 1900 to 2200 respectively on Rockauto.com just my $.02
 
i think you may want another shop to take a look at it. pretty rare to be in that bad of shape. but for that kind of money you can get a 13mm monster built.
 
second opinion!!!!

then if its still looking that bad, get a reman stocker.


that price is outlandish!!!!
 
took him for a ride already, just on tear down and inspection costs i'm sure
 
X3 on Seth at Diesel Performance Engineering, sounds awful high
 
The governor is oil bathed as well as the cam and roller lifters. You also stated the bearings are shot as well. This is all related to oil quality for these oil lubricated components.


Many times the plungers wear into their respective barrels with a stock type plate setting and rack movement. If a rack position is changed this can start a wear groove in another location. When I say groove, it is not a visible groove, just a micro level wear pattern between the p&b.
 
Vaughn this is Jake we met at the dyno at Motor Mayhem in Meridian. If you are coming back to Meridian anytime soon there is a good pump shop in Boise called Master Tech Diesel Injection. One of the guys from the Idaho Club works there.
 
Don it could be the previous owner used a non-diesel rated oil, he was diesel clueless for the most part and had the truck for over 100,000 miles. I looked at it today, to my eye the plungers looked fine except at the ends around the delivery port area the mirror finish was worn dull, they told me they're at the point they need replaced.

I will give Seth a call at DPE, thanks for the suggestions you guys. Hadn't heard of DPE before.

Jake I'll talk to Motor Mayhem as well, I didn't realize there was a good shop down that way.

I went by and looked at the pump today and they didn't even put it on the stand, said they stopped doing that a couple years ago, now when they come in they just tear 'em down. Luckily he doesn't have that much time into it but it will cost about $150 what he's done so far.

In the end I want a quality pump in that truck, I was planning to sell it but I'm thinking I'll keep it now.

i have a 215 pump on my 95 that has 450k on it, never been touched. i just put a 5 k kit in it and a 100 plate. i have never had to replace a worn out p pump, and i have had many 300k plus trucks.
