Repair or replace inj pump 5085M?

Can a common rail inj pump system similar to the pump on a JD5085M(900 hrs) be repaired or do they require replacement? Granted I understand a lot depends on correct maintenance procedures. Anyone know the flat rate hrs to R&R inj pump on same tractor?
Thanks,Jim

I have to ask what is wrong with your pump? I work on a pile of HPCR engines and I haven't had to replace but one pump. It was on a QSK19 cummins with a lil over 19,000 hrs. Just curious??

It's not my tractor but belongs to someone on another Tractor forum. He stated tractor had 900 hrs on tach,quit running and local dealer stated inj pump needed replaced to the tune $1700 for pump and $650 for labor. I think $650 to R&R inj pump is way too HIGH

Tx. Jim, at the JD dealer I work at we do end up replacing a few HPCR pumps a year. That being said more needs to be known as to what other trouble shooting was done. When we have had to replace pumps it was the last option as we don't just jump in the replace the pump bandwagon because generally those pumps are pretty robust. As far as the labor rate I am not sure as we are not a flat rate dealership and at our labor rate ($105) that seems about right as you have removal, instaliation, test running, clean up. I am not familiar with that engine as far as time for removal goes( I work on combines sprayers and planters)

Tractor owner stated he purchased tractor with 850 hrs on tach. He performed maintenance(filters & fluid) and 50 hrs later tractor died while applying fert. That's all I know. Man 6 hrs sounds like a lot to R&R an inj pump. I would think it could be accomplished in 1/2 that time. You state your dealership isn't a flat rate dealership but I'll bet JD still pays warranty claims by flat rate similar to when I was dealer service manager.

Well, Im assuming that the dealer isnt just guessing at it. Im sure they have been through the proper test to verify the issue. 6 hours is about twice what i think it should take. But it is exactly what I would expect a dealer to charge. Man clocks in on the job. Gets the tractor in the shop. Replaces the pump. Test his repair. cleans the tractor. cleans his bay. Does a write up explaining what was done. All this cost money.

After serving several years as a JD dealer service manager I think I fully understand the technicians procedure. You left out the scheduled coffee breaks that the technician "fails to clock out/in" on the repair order!!!! :wink:
PS: you also left out the part about diagnostics.

I personally asked Tim S about R&R time and he thought it was about twice too much.

Update: Tractor owner reported on the other tractor site that JD dealer is going to replace inj pump under extended warranty under an emissions warranty.

Yes they do pay warranty by flat rate. I will see if I can find what the flat rate manual says for pump removal.

TxJim,

Hopefully the gear comes off the pump shaft easy enough to allow pulling the pump. Got a call on a Friday evening about 5:00 pm at the dealer, local dairy had a 8230 they used for grinding hay and feeding cows. Anyhow, tractor dies about halfway down the feeding alley and wont start. I drive out there, plug in Service Advisor and pull codes, and start through diagnostics. Go into reading and see that there is no fuel rail pressure. Check the wiring circuits etc. and find that the pump shaft broke inside the pump. Its now 7:00pm, flies are so thick it looks like rain clouds, it stinks, its wet....you get the idea.

So I pull the front cover off and yep, I can wiggle the pump gear and shaft. I call the parts guys and tell them to send out a new pump and gear. I install the gear puller and.....you guessed it, gear will not pull off the shaft. I break both bolts off in the gear pulling on it. I tried heating the shaft...etc. Nothing. Now its 11:00pm, I get another tractor, drag this 8230 out to the end of the alley and go hook another tractor to their feed wagon so they can continue feeding.

In the meantime, parts had told me they had the pump, but no gear. We have a Cessna 182, it flies 3 hours to a dealer that has a gear, and comes back. Its 3am, I have cut out the shaft with an air grinder, cleaned up the parts, and get the new gear installed, install the pump, time it, get it running, rehook up the feed wagon and get everything going. Its now 7am, been on that job for 13 hours......

Sooo I say this, In a perfect setup, timing the crank/pump removing the pump, installing the new one etc, would only take 1-2 hours if everything was perfect. I dynode all my work to verify no leaks, and performance was correct. Then wash it up and release it.

SMT (Service Marketing Times) are generated most of the time off warranty claims history. Sooo lets say 50% are nightmares, and 50% go smooth...it would be easy to see the 6 hour charge for AVG times. Bottom line, unless you have the special tools, Service Advisor to diagnose properly and the know how, plus warranty procedure for working on it....6 hours...it is what it is. Is it right?? If you cant fix it yourself, I guess it is!!

My 2 cents

As a former service manager I understand about the repair calamities
that rear their ugly head. It always amazed me how engineers seemed to engineer things to be difficult to repair. I'm glad I own a 4255 not a 5085M!!!!!!!!
