Hydraulic flow chart for Ford 601

[frank d mayo]

Anyone have a hydraulic flow chart for a Ford 601 workmaster tractor? I'd like to see the flow diagram of the entire top plate from pump to top plate and internals then back to pump. I'm thinking the spool valve inside my top plate is where my problem is located.

There are three digrams in the Ford Service Manual, for Raise, Lower, And Neutral. Here is Raise.

Thank you for the diagram. My 3 point lift sometimes works sometimes doesn't. The control valve, unloader valve, and safety valve all appear fine. BUT.... I found the Pilot Lift check valve at the front of the top lid seized in my Ford 601 work master 1958??? (hybrid finding various year model parts on it . I'm still trying to get it out... I do believe that is the problem for my 3 point hitch lift not working. BTW the part number is NCA668d and the ball and spring is NCA674A. I found NCA668d new at GT Engine Parts order on line ... so I ordered it. This parts fits many many different tractors too New Holland, Club Cadet, Case, and many more. But it is hard to find. This diagram was just the thing I needed to understand the hydraulic flow. thank you. I've decided to just rebuild the entire top lid and Hydraulic pump. I already rebuilt the High Pressure Diesel Injector Pump cost me 185.00. Beats buying it new 1900.00 So why not do the hydraulic pump too
