I've got a 190XT with a bad pump, they want around $700 to rebuild it and I was wondering why so much. There must be more to it than just replacing worn out seals does anyone know what is done? I've never seen a breakdown on pumps in any of the manuals and I would love to tear this one apart to see what makes it tick but don't think they would like it if I brought it in in a basket. Also how can they set the pump without the tractor, I'd hate to put it back on and end up with a big loss of hp. Just wondering, thanks in advance.

I have a pump for this tractor that I bought at a sale and the guy said it has hardly been used and it does look that way. I bought it thinking I could use it on my 220 but I found out later my 220 uses a 4 roller pump and this is a 2 roller I believe. I would sell it for what I paid for it $180 plus freight.

All you should need to do with it is have it checked to make sure it is set for the horsepower you want it to have.

The numbers are Model # DBGFC637-X76AF Serial # 1275680 Mfg # EX35605

Let me know.

Kirk, thanks but I just dropped the pump off to get rebuildt, took the injectors in too, figured might as well get every thing gone thru as long as the tractor was down.

I have a diesel pickup and have learned a bit about the injection pump because of some problems I had.My truck has a Bosch fuel pump and the local service place has a special clean room to repair and calibrate the pumps due to the extremely close tolerence parts they contain.The smallest particle of dirt could enter the pump and destroy it.That is why it is so critical that the fuel/water filter sepatator is maintained on schedule.The type of tools and equipment required to repair a broken pump is well beyond what we could do in our garages or basements!Not only is this a problem, but they also have test benches set up to calibrate the pump to deliver the correct amount of fuel to the engine according to the published specs for your tractor.Another reason we can't repair one at home. This is definately a job for the guys who do it every day.

listen to don--
the pump must put out a specific cubic centimeters of fluid duirng each revolution and each plunger must put out exactly the same amount. think what would happen if one cylinder gets 25% more fuel than the rest, each time it injects. you can end up with a real mess. The price is outrageous, but is because you have no other options.

One final comment-you had asked if they replace seals inside the pump.To give you a better idea of the tolerances these pumps are built to, most of them don't have any seals on the high pressure side.The fuel is delivered to the injection nozzles in my pickup engine at 10,000 PSI.The only thing that prevents leakage around the pump pistons is the fit of the pump pistons in their cylinders!How is that for a tight fit? Now can you imagine what would happen to one of those pistons if you happened to get a grain of sand in there?

yeah I see your point I'll let the pro's rebuild it, but you do realize that even the pro's were once amateurs, thought maybe it wasn't that difficult. thanks, Gene
