technical reference for M670 hydraulics

sam c · Oct 6, 2015

Greetings,

i have an M670 super that was leaking hydraulic fluid around the quadrant and remote valve control levers. I took it a general mechanic with lots of tractor experiemnce. He fixed external leak. Unfortunately, no 3 point lift. With ptressure gauge no hydro pressure, there must be an internbal leak inside the valve body

i have the moline rrepair manual for 670 super and the generic IT manual for several similar moline models for him to reference.

Lookinng for general wisdom on what to fix next or a suggestion for a repair manual that maybe more specific for this type hydraulic repair

If the O ring is replaced or the return springs on the levers were replaced Ive always heard that the valves need to be synchronized again, not to say that something else might have been overlooked. Does your 3 point lever move like it did before? Can you feel a detent (some resistance) when it is moved?
