Skid Steers with an auxiliary hydraulic flow of 15 gpm or less - Figure 29
Assemble straight male adapter (6) to “K3” port on valve as shown in Figure 29. Assemble JIC swivel run tee (9) to straight male adapter (6). Assemble 90° male adapter (10) to “K2” port on valve.
Skid Steers with an auxiliary hydraulic flow greater than 15 gpm - Figure 30
Assemble straight male adapter (6) to “K2” port on valve as shown in Figure 30. Assemble JIC swivel run tee (9) to straight adapter (6). Assemble 90° male adapter (10) to “K3” port on valve.
IMPORTANT - The location of the JIC swivel run tee will ensure that proper flow is provided to the backhoe for smooth operation. The flow into the valve from the skid steer is divided between the two outlet ports “K2” and “K3”. The hydraulic flow is split so that 60% is flowing from the “K2” port and 40% is flowing from the “K3” port.
4.Assemble 90° JIC adapter (8) to through port of swivel run tee fitting (9).
5. Assemble 45° JIC adapters (7) to both “In/Pressure” and “Out/Return” ports on the backhoe bulkhead connection.
6.Connect 24” hydraulic hose (11) between 45° JIC adapter (7) on backhoe “In/Pressure” bulkhead con- nection and single 90° male adapter (10) located on top of flow divider valve.
7.Connect 24” hydraulic hose (11) between 45° JIC adapter (7) on backhoe “Out/Return” bulkhead con-
nection and JIC swivel run tee (9) on flow divider valve.
8.Assemble quick coupler (supplied by customer) to pressure line hydraulic hose (supplied by customer) and connect free end of hose to 90° male adapter (10) at bottom of flow divider valve.
9.Assemble quick coupler (supplied by customer) to return line hydraulic hose (supplied by customer) and connect free end of hose to 90° JIC adapter (8) on flow divider valve.
10.Carefully route pressure and return line hydraulic hoses to tractor hydraulic connections. Remove dust caps from tractor hydraulic connections and connect hoses to the appropriate port on tractor.
Testing Backhoe Hydraulic
1.Start skid steer loader engine.
2.Set parking brake and engage auxiliary boom hydraulics so that oil flows to backhoe. NOTE! Consult skid steer Operator’s Manual for proper operation.
3.Exit skid steer and sit in backhoe operator’s seat.
4.To remove air from backhoe hydraulic system, slowly cycle all backhoe functions (stabilizers, boom, dipperstick, bucket, and swing) several times. Be sure to cycle stabilizers first and then lower both sta- bilizer arms into operating position before cycling other backhoe functions.
5. Exit backhoe, disengage auxiliary boom hydraulics, stop engine, and check skid steer hydraulic fluid level.
