HYDRAULIC HOSE CODES AT VALVE
Hydraulic Hose Band Mark Color Codes:
Color Coded Plastic Band around it. Some Bands are a solid Color and some are Colored with a
Stripe. The purpose of the colored bands are to provide a quick reference for hose and port
connection. A metal band is also attached to the hose, on that band is an Alamo Industrial Part
Number for reference if needing a replacement hose.

Diverter Valve.:
The Diverter Valve bolts onto the front frame mount bracket on the LH side of the tractor, the holes
are in the bracket (See Figure 5 & 6). The Diverter valve is a electrical operated valve that allows the
hydraulic pressure to be shared to operate two (or more if valves are stacked) functions with a single
pressure supply. This valve is strictly a diverter valve and is designed to direct the pressure, not regulate
the flow or pressure.
The Port openings on this diverter valve are marked with letter number codes which show which
port is connected to which hose and where that hose connect on other end (See Figure 4, 5 & 6))
