how can i tell if the hydraulic head needs to be replaced on the roosa master fuel pump model jdb331 al 2405.i bought the 301 john deere from the estate of my neighbor. the grand son had taken the pump off the tractor, when i got it the pump was a bag of parts. the local repair shop wants $1500.00 to re build the pump the tractor is a industrial front end loader a nd not worth that much money i am looking for a diagram and a kit to rebuild
 
The $1500 seems a little steep, I got one rebuilt for $600. I do not know if you can tell it the head is worn without having it on the tractor, or on a test bed.

Why do you think it needs rebuilt?
 
The cost is always higher on a bag of parts than it is with a pump....
Cleaning up someone else's f**up is always more time consuming...

I had a pump off an Allis 190XT rebuilt some 10 years or so ago and it cost me around $800 for it and it was a roosa master pump so that price is about right for today's price. Ya sad to say but that is how it is now days.
 
Has the rotor been taken out of the head? Not a job for an amatuer (sp?) if you are trying to save money.Head and rotor may or may not need replaced. I could take a look at it if you want.Wouldn"t charge you to look. E MAIL IS OPEN
 
Had a roosamaster done two years ago for my IH460, was 600 dollars, they are one of the cheaper old school pumps to do!
 
Very True!!!!! I am in the tool and die biz, and I hate it when someone tries to "Help me out". by taking things apart. Once a simple 2 hour job wound up costing 10 grand, because the was a box with several hundred parts, that had all been hand fit..
 
all 2 cycle mechanics hate to see a basket case come in. When you get it fixed, its so expensive they don't wanna pay for it so they leave it with you. Even tho they swore it had sentimental value & they would pay whatever it takes...
 
I agree that getting a basket case is a pain, but if a pump shop charges extra because of that, they are doing nothing but screwing the customer over.

Almost all the injection pumps I (and all my co-workers) run are built from scratch. I will pull the parts out of the crib, assemble them and run the pumps of on the test bench. If a pump technician cannot be given a basket full of parts for a pump and rebuild without any issues (where does this go type questions), they're not very good.

I agree with you to a point... but I think it gets to be a question of how much time do you spend figuering out where some things go... or more pertinently... what parts are missing.
The numbers tossed around in the first post are not really out of line for what I've been quoted on worst case scnearios where it needs a rotor/head either... at least around here. That being said, pump shops around here are not noted for doing low price work...

Hi sim,

Basket cases don't scare me, send me an email
with a phone # and I'll either get you thru it
or I can do it for you. I have test stand and
parts as well as JD calibration specs.

You are also correct. I think that because I work in Stanadyne's Engineering Center, it makes it a little easier for me....I used to "basket case" pumps. If I am given a complete pump to work on, I get that "wow' feeling.

Probably 95% of the pumps I build are from scratch, with brand new parts I pull out of our crib. The remaining 5% or so, are either new pumps I strip partiality down and rebuild with experimental hardware, or old pumps that have "x" amount of hours on them or the tests are over. I rebuild those, with new hardware if needed or wanted, and/or O-rings (the #1 replacement item on a pump).

a roosa master us such a simple pump its amazing. If you have done more than 1 of these pumps I think you can figure out where the pieces go in about 1 minute.
