Earthforce Hydrostatic Help Please

[martinrdcustomz]

hello. i am brand new to the forum and i just purchased a 2000 Earthforce EF1D. i have a problem already...it drove around fine for awhile playin in the yard then all of sudden the drive started to go in and out. it would drive for a couple feet then it would just stop pulling then a couple seconds later you could feel it kick in and take off again then do the same thing...i have no idea where or how to check fluid. i have no manual with it. there is fluid on the hydro pumps underneath like its leaking somewhere...does the hydrolic fluid supply the hydrostat drive? basically any input would be helpful. thank you

Been quite awhile since I worked on one of these but if memory is correct. The hydraulic tank is part of or just under the right side step to the operator platform. Check the fluid, the filter is also in that tank. Hydro pump & loader/backhoe pump are 1 unit. Remove the floor plate to see the pump and drive motor, look for leaks.

thanks for the reply. i removed floor board and noticed that when i pushed on gad pedal forward and backwards...i am gettin hydro fliud pushing up past the 2 pegs that the pedal pushes against.. im thinking thats not supposed to do that lol. so i pulled the 2 bolts per pegs and there are 2 o rings in each one that i am gonna replace...gotta wait til monday or tuesday til local o ring shop is open. also checked filter...says earthforce all over the filter so im assuming the filter was never replaced...800 hrs on machine. so i will start the task of trying ti cross reference and try to find a filter for it. does anyone think that the hydro oil leaking out around the pedal post could be causing me to loose presssure and therefore be my problem? just hoping thats all it is but dont wanna get my hopes up lol. thanx

It has been 10 yrs. or more since I have been inside one of those pumps, I'm fairly certain those pegs are the pilot pressure pistons so oil leak there can drop the pilot pressure and not stroke the hydrostatic pump. Could be just weak O-rings or some type of excess pressure build up that is forcing oil through the O-ring.

Bobcat purchased this company and had parts support for it. They made some design changes and rebranded them as B100 - B300 & also as IR BL275 - BL475 models. There are 2 filter elements to that filter assembly. 1 is return oil the other is suction filter. Part numbers are 696403 & 6961187. The EF1 is pretty much the same as B100.

If you run into more problems you may want to post in the Bobcat Construction Equipment to see if anyone else has had similar.

my son has a bobcat B200 4x4 he did some horse trading and ended up with it . it had hydro issues when cold it move then slowed down to nothing. well with a lot of research these machines r made in czech. with many diffrent brand name tags of other companys. but there about all made from the one company..there main problem is the hydro pump period they don't have a good cooling system and the fliud gets hot and breaks down and then u have pump failure.. bobcat wanted almost 6000.00 for the pump. we searched the internet and found a company that handles old new stock of the pumps complete for 2900.00 ... so we purchased one and the bobcat works wonderful.. the hoe and frt bucket worked perfectly with the bad hydro pump... and we could not find a hydraulic rebuild company that could find any parts to rebuild the old pump. r pump wass made in Italy... the company name that handles the old stock new pumps is Hydraulic Pumps & Drive Motors > Bobcat, Case, John Deere, New Holland, Scat Trak, and more! | Loader Parts Source.com and if ur keeping the machine u may want to up grade the cooling for the hydro system if it under the floor boards move it up in frt of the radiator for better cooling hope this helps ...

Yea I'm 99.9 percent sure that's what's wrong with mine but mine is the older 1999 earthforce EF-2. I have attached pics of the tags on the hydrostatic pump. Not sure if it's the same as the one for B200.

You recon the one from LPS for the B200 will fit mine?
