Hydraulic crossover valve help

Psycho Billy · Jul 23, 2015

Hello, my wife and I just bought a nice old 1958 Minneapolis Moline 335 Industrial with a loader. The hydro controls for the loader have a crossover valve and some additional ports to add remote hydraulics, but that's all the seller could tell us. Has anyone seen this before? Which ports are which. And if I add the lines, do the existing handles control them or are they independent?

Thank you!

Does that "crossover valve" allow for a float position for the bucket? Sounds similar to my Ford backhoe.

(quoted from post at 08:02:14 07/23/15) Does that "crossover valve" allow for a float position for the bucket? Sounds similar to my Ford backhoe.

How could I tell if it is a float control or a crossover? It only s out about 3/4"

Float valve or function allows the connection of the two ends of the boom cylinders so that the boom will move up and down with
the contour of the ground ("float"). No pressure down or up as oil is just going from one end of the cylinders to the other.
Most modern valves with float function have it as a part of the boom control valve. Crossover may allow float by connecting the
two circuits of the boom cylinders? Not sure on this application.
