    earthforce {bobcat}B250

    Default bobcat B250

    Bobcat B250,{earthforce250} Still can;t find problem with no brakes and little drive power. Purchased parts and service manuals. They refer to problems of "main relief valve", etc but in the hundred or so pages never show any of these items in thier locations, In addition these manuals never describe the function of the many "valves" they show. The manuals are of little value unless you ned to know where an obvious nut is. Anyone know of a web site with good details or some other publication that shows the function of these various items. The machine stilll has NO hydro brakes and little power foward or reverse. PLEASE Help Thanks

    Bueno la maquina de por si es lenta al ser hydrostatica la velocidad la consigues subiendo las revoluciones del motor. Mi equipo es B200 bobcat.

    I'm working on a machine with no hydraulic paking brake, no reverse and sluggish in forward. I'm looking for an answer myself. Went threw a lot on the machine

    Bueno el sistema de freno del B200 que yo tengo es mecanico. Referente a lo de reversa hay que empesar por verificar si la bomba hydrostatica esta tirando presion hacia el pedar de palante y pa tras.

    Verifica si tu equipo tiene esta misma bomba hydrostatica de las fotos.

    Probably best to post on the Bobcat Construction Equipment Forum. If you're lucky SSDoxie will happen along with a response.

    No hydraulic brake with no or sluggish drive indicates low or no charge pressure. Possible charge pump failure, charge relief stuck, flushing valve stuck open, or hydrostatic pump worn so by-passing internally.
    Here are couple pages about testing charge pressure and flusing valve. If charge pressure is low and will not adjust, the pump set needs to come out for inpsection.b250 charge pump,flushing valve test.pdf
