Test Hook-up No. 3: Charge Pressure and Implement Relief Pressure (Fig. 20)
Gauge Connection
Connect a 1000 PSI hydraulic pressure gauge to charge
pressure gauge port.
TEST A: Charge Pressure
1. Make sure hydraulic oil is at operating temperature.
2. Operate engine at full speed:
3600 ± 100 RPM
Reelmaster 216:
3200 ± 100 RPM
Reelmaster 216-D:
3. Traction pedal and lift valve in neutral. Parking brake
engaged.
TESTER READINGS: 70 – 150 PSI.
TEST B: Implement Relief Pressure
1. Make sure hydraulic oil is at operating temperature.
2. Operate engine at full speed:
3600 ± 100 RPM
Reelmaster 216:
3200 ± 100 RPM
Reelmaster 216-D:
3. Traction pedal in neutral and parking brake engaged.
4. Pull lift valve lever to raise cutting units and hold lever
so systems goes over relief.
TESTER READINGS: 700 – 800 PSI.
CAUTION
Implement relief pressure should not exceed
800 PSI.
NOTE: If pressure is within specification but the cutting
units do not lift or lift slowly, check for mechanical
binding, or internal leakage of lift cylinder.
