A - SCV I Couplers

B - SCV I Lever

  1. Connect jumper hose to SCV I couplers (A).

  2. If SCV is equipped with flow control, open flow control knob fully to allow maximum flow.

  3. Start engine and set idle to 1200 rpm.

  4. Hold SCV I lever (B) forward or rearward until hydraulic oil warms to operating temperature.

  5. To check warm-up progress, turn steering wheel side-to-side. When wheel turns smoothly without hesitation, oil has warmed to operating temperature.

  6. Return SCV levers to neutral.

  7. Return flow control knobs to original setting.

  8. Remove jumper hose.

A - SCV I Couplers

B - SCV I Lever

C - Continuous Flow Detent

  1. Connect jumper hose to SCV I couplers (A).

  2. Select SCV I detent to continuous flow detent (C) (no kick-out).

  3. Adjust to approximately medium oil flow.

  4. Set engine at 1200 rpm. Move SCV I lever (B) rearward to detent position until hydraulic oil warms to operating temperature.

  5. To check warm-up progress, turn steering wheel side-to-side. When wheel turns smoothly without hesitation, oil has warmed to operating temperature.

  6. Return SCV levers to neutral.

  7. Return detent selector and flow control knobs to original positions and setting.

  8. Remove jumper hose.
