Using Hydraulic Motor Return

Hydraulic motor return kit provides a convenient port to access the tractor low pressure return circuit.

Remove cap from hydraulic motor return coupler (A). Connect return hose to coupler, making sure hose end and coupler are clean.

Using the motor return coupler will prevent:

• Inadvertent reverse operation
• Pressurization of auxiliary function return line
• Potential flow checking of the return-side SCV coupling

Examples of implements which cannot withstand high pressure applied to both ports are:

Hydraulic motors which have the return and case drain ports connected. Failure of the motor housing or shaft seals may result if the return line is pressurized.

Auxiliary control valves located on the implement may allow unexpected movement of cylinders or not function correctly if the return line pressure is too high.

NOTE: Motors without overrunning check valves should be connected to the motor return coupler to prevent return line pressurization when SCV is returned to neutral.

Combining of return flows through a single coupler may result in excessive return line pressure. Use the multiple return coupler kit if additional return circuit connections are required. (See Using Multiple Hydraulic Motor Return in this section.)
