TEST A: Traction Pump Flow
1. Make sure hydraulic oil is at operating temperature.
2. Block up one front traction wheel off floor. Place
blocks in front of remaining wheels.
3. Operate engine at full speed:
3600 ± 100 RPM
Reelmaster 216:
3200 ± 100 RPM
Reelmaster 216-D:
4. While watching flow and pressure gauges, slowly
push traction pedal into forward until 7 GPM is obtained.
5. If pressure rises above 600 PSI, proceed to Test B If
pressure remains below 600 PSI proceed to step 5..
6. Use flow control valve to obtain 800 PSI at 7 GPM. It
may be necessary to depress the pedal farther to main­
tain 7 GPM as pressure rises.
TESTER READINGS: GPM Flow — Not less than 7
GPM at min. 800 PSI. RPM — 3000 minimum.
