Bobcat B200 hydrostatic pump

[briker57]

I need a hydrostatic pump for my Bbcat B200. Does anyone know if you can put a replacement in by another MFG. Bobcat does not sell repair parts for their pumps so if I buy one from them and it goes out again I have to shell out another $6,000.00 where as if I get a pump made in U.S.A. hopefully I can get replacement parts and get it repaired locally. Also does anyone know if the hydrostatic pumps are a problem on them or if I just got a tractor that was not maintained. I only had the tractor about 2 months when it went out. Thank You

Is there any manufacturers name tags or model numbers on your existing unit? You may be able to fit another model in there but I doubt it would be a direct interchange. You might have to get different hoses, fittings, redo control linkage etc.

Another option might be to try calling or looking at this website. loaderpartssource.com Another forum member looking for older Bobcat parts posted this awhile back. He stated they had parts available for his model, not sure about yours.

good luck

How do you know you need a new pump ? Did it blow up like a hand grenade ? The safety circuit always malfunctions after a certain time and then you get no drive forward or backward. Fixing it requires bypassing the safety valve or simply wiring it to be "permanently on" when the key is on.

So what were your symptoms ?

The inner gear on the charge pump broke in 3 pieces. I caled a local hydroulics shop that I was told was a good and honest one. They said to bring all the pumps along. Their tech checked them out And siad that thay were shot. There were a lot of scratches on the plates and on the pistons. He said it was probably due to not being maintained ie. dirty fluid. H also said that I would have to clean the whole system before I put a new pump on. Any suggestions for cleaning the system?He said that he could not get the parts because he never heard of the company. The tag on the pump says Axial pump made in Italy serial #000415 date 5-01
thenk you

Amazing failure, considering there were only 1000 hours on it. Bobcat does carry spares and there are other shops that will repair those hydros. The smaller units have Italian pumps and the larger units apparently went with rexroth equipment (EF4 &5).

You might consider completely replacing the entire hydro pump with one of the units from Surplus center

The auxiliary pump rides on the back of the hydro pump and some of the pumps listed have that configuration too.

Did anyone ever find a solution to this issue - as I have the same, i.e. need parts or replacement for Hydrostatic pump, with Tag "Axial Pump, Made in Italy". It would be great to know if you found out who made this pump and if and where parts or replacement can be found. Bobcat is offering a replacement for $5000!

Local hydraulic rebuilders are hesitant to take the pump apart without being able to secure parts, sealkits, etc. I expect this is a HP Pump which I believe has been consumed into bondioli-pavesi. I hope to find a US distributor for such if this is in fact the company responsible for this pump.

Any help is appreciated. I will post a solution once I find the correct one.

Thanks, Greg

Hi all, i'm a field technicien, and last monday, I have worked on a T200. I have replace the radial seals located on top of the pumps on the driving shafts.In my case, the pumps were supplied by the make "SAUER DANFOSS" made in Italy. Tomorrow, I will ask my boss if he had already rebuild pumps like them, and if he can get rebuild kits from Europe.

 

[gjb012]

Thanks for the info and the help.

I have taken the pump to a repair shop that has some experience with these.
They advised me that Axial Pump Italy was taken over/purchased by Poclain France.
The pump in the tractor is very similar to the PM65 model they still sell.

The shop has taken apart the pump and it is completey worn out and needs new main and charge pump internals. These can be sources from Poclain but it will take 12-14 weeks to get these parts.
Sadly I have just ordered the new replacement pump from Bobcat as they can get it to me in a week.

I also investigated into getting a replacement pump made by a US Mfg, but after extensive research there is no simple plug-n-play pump that will fulfill all the specifications of the original. Ugh.

If you do find that you can get rebuild kits or parts for these pumps it would be beneficial to others here, as waiting 12-14 weeks to get parts is pathetic, when they are probably sitting on a shelf in a warehouse in France and can be DHL'ed to the USA in 2-3 days!

Thanks again - I will post a complete solution to this saga when I have the tractor running again.

Any more info on this? I have a 1999 earthforce ef-2 and when the hydraulic fluid heats up it will barely move forward or reverse. I need to rebuild the hydrostatic unit and was wondering if there are any part interchange numbers or replacement/rebuild part numbers available

 

[gjb012]

Sounds like you have the same problem I did and many others have reported to me since I posted this originally. I now believe this is a common issue with these machines, i.e. premature internal wearing of the pump. I was unable to get individual part numbers for the internals of the pump but I did not look that much as I was not prepared to do the internal rebuild myself. NH Hydraulics, NH, USA would do the rebuild for me, as they had access to the parts and manuals through their Poclain rep. As posted, I ended up buying a complete unit as I could not deal with the lead time for the parts. I would check the tag info on the pump and see if it is an Axial Pump, as I am not sure a 99 EF used the same pump as a 2002 B200. If you want to go the internal replacement route, you need to have a Poclain supplier get you the parts list. I have the repair manual which I am happy to send you, but it does not list part numbers and is too big (4 Megs) to upload to this site.

Please advise if I can be of any further assistance.

Thank you that info does help. I haven't pulled the pump apart yet because I wanted to have the internals ready before taking it apart. I would definitely appreciate the manual. Not sure of the forum rules here but ill try and send you a PM with my email address. I am going to call around tomorrow to try and find a supplier once I get the pump off. This is definitely an ongoing problem with these machines. I've seen MULTIPLE forums about pump failure.

 

[Austia001]

This is the number on the Hydrostatic pump on the 1999 EF-2. Anyone have the same pump on theirs?

I am in a position where I for sure have to replace my main hydraulic pump since it cannot make relief pressure anymore and the machine has lost a considerable amount of power in the loader and hoe.

The HST works (except for the safety valves which are on the blink due to electrical issues) but I figure I may as well replace the HST at the same time, replace any hoses which I have not already replaced, since they always fail at the most inopportune time...

The 5000psi working pressure hose and DKOL fittings can be had from K Series No Skive Hydraulic Hose Crimp Fittings | Hydraulic Hose Hydraulic Hose Fittings (just scroll down till you see the listing of DKOL fittings) "The Hose guys" will send you a sheet with dimensions for doing the crimping so you can take the hose and fittings to your local hydraulic guy to make up replacements for you. I have already replaced every hose on the hoe and not had a bit of trouble with any of the replacement lines. I think the labor charge for cutting and fitting the hose ends for me was $60 for the hoe, after I bought the hose and fittings. I made the hydraulic shop a drawing indicating the length and which kind of fitting was needed on each hose end and it worked out great.

I am looking to use a Rexroth A10VG HST pump Bosch Rexroth Mobile Hydraulics

I can't tell if the surplus one I found for $900 will give me the exact same functionality as before (one may be able to stall out the motor using the HST for instance, without a load valve) but given that the main purpose of the machine is digging while stationary or lifting items and then going somewhere with them, I don't believe that I will sufferer a substantial loss. Perhaps more finesse will be needed when moving dirt with the loader ? Saving close to $7000 on the rebuild (not counting labor) will be worth it to me, given that I am not charging for my seat time...

The biggest question on my mind is the specification of the gear pump. 3000psi gear pumps which will fit are <$250, but the page in the specifications section of my B200 manual is conveniently blank for the HST and gear pump so I don't know if I actually need a 4000psi working pressure gear pump or not (the relief on the hoe cylinders is set to 4000psi). I personally assume that the extremely short life that folks are seeing with the pumps on this equipment are due to gear pumps being used that are likely only designed for 3000psi in the first place combined with ineffective oil coolers on the B200. So my plan is to add a large auxiliary oil cooler to my machine at the same time and lower the oil temperature. I have not found any 4000 or 5000psi working pressure gear pumps yet, and the pump sold by loader parts source looks just like the $250 pumps being sold at Surpluscenter except that they want $900 for it and Bobcat wants $1300 for it. I figure that if I get another 1300 hours out of a $250 gear pump, I can just keep replacing them till the cows come home and be way ahead of giving Bobcat a dime.

I have found a lot of info regarding these bocats on the "out crop acres" website
