Use Deluxe Rear SCV to Operate Hydraulic Motor

RXA0149443-UN-22JUL15

A - SCV I Retract Coupler

B - Adjustable Flow Control Valve

NOTE: To understand motor features, refer to implement operator’s manual.

If equipped with deluxe rear selective control valve (SCV), use SCV I retract coupler (A), with adjustable (internal) flow control valve (B) for hydraulic motor operations.

IMPORTANT: Never regulate SCV I oil flow with an external flow control valve. Having two flow control valves in the same hydraulic circuit overheats oil, causing component malfunctions and damage.

DO NOT use deluxe rear SCV for any low flow, high-pressure applications such as SEEDSTAR™ variable rate drive planter motor or active downforce circuits. PTO driven hydraulic motor is recommended for low flow, high-pressure applications.

To regulate oil flow when operating a hydraulic motor with any standard valve without adjustable flow control, use an external flow control valve.

Recommendations to Avoid Hydraulic Motor Damage

Use hydraulic motor return coupler (if equipped) for implements having:

• Single directional hydraulic motor.
• Hydraulic motor with low-pressure shaft seal.
• Hydraulic motor with internal case drain.

Use hydraulic motor case drain connection (if equipped) for implements having motor with case drain line. Refer to “Use Hydraulic Motor Case Drain Connection—If Equipped” in this section.

IMPORTANT: If implement motor is not equipped with return coupler, do not use “neutral” lever position to stop hydraulic motor; use “float”. Internal load check valve will cause backpressure damage to hydraulic motor or hoses.

Hydraulic Motor Hose Connections and Control Lever Operations

IMPORTANT: Use only SCV I of rear SCV for “continuous” (motor) applications. SCV I of rear SCV is for high flow and lower pressure application (motor).

DO NOT return hydraulic motor directly to sump via port on differential case, except intermittent high-pressure applications, such as post pounder.

2. Move SCV control lever full forward, into “float” detent.

3. Connect hydraulic motor supply hose to the retract coupler and return hose to the scv extend, case drain or fast dump port as required by application.

4. Deluxe Valve: Set SCV control lever detent for continuous “motor” operation. (See “Set Rear SCV Detents” in this section.)

5. Start engine.

6. To activate hydraulic motor, move SCV control lever forward to ”retract” position.

7. IMPORTANT: To stop hydraulic motor, do not use “neutral” lever position; use “float”. Internal check valves will cause backpressure damage to hydraulic motor or hoses.

   To stop hydraulic motor, move SCV control lever fully forward into “float” detent.

8. Shut off engine and disconnect hoses from couplers.
