Hydraulic help

[Pat Marchwick 88]

Is there a hydraulic Trouble shooting chart anywhere for wheelhorse hydrostatic and hydraulic system ?

such as :

           Problem                                                                      Possible cause

tractor climbs slope fine in reverse but not in forward, .        Bad spool valve ?

tractor does not move.                                                            Low fluid, plugged fIlter ?

lift cylinder works but tractor will not move.                              Bad shift linkage!  Internal oil leak in valve?

 

looking for help figuring out my tractor weird behavoir

to go forward up a 15 degree incline I have to find a sweet spot with the directional handle. Too far it won't climb and irs not a lack of power. On level ground it works ok.

thank you

From what your describing sounds like you have weak or broken spring the charts below are from the Sundstrand used in Allis and Simplicity. But the acceleration valve is a common component on all hydro units.
