Anyone have a hydraulic schematic of the Hi-Low system on a 3140/2940 or similar? I want to know the flow paths in the top cover/valves.

Thanks

No longer needed, figured it out.

Top cover was siliconed at some point without a gasket, blocking the drain for the Hi/Low spool, pressuring the cover and forcing the spool into low.
