Procedure for Piston (Traction) Pump Flow Test
Thistestmeasurespiston (traction) pump output (flow).
During this test, pump load is created at the flow meter
using the adjustable load valve on the tester.
IMPORTANT: Traction circuit flow for your Reel-
masterisapproximately30GPM(113.5LPM).Use40
GPMHydraulicTester#AT40002(pressureandflow)
for this test (see Special Tools in this chapter).
1. Make sure hydraulic oil is at normal operating tem-
perature by operating the machine under load for
approximately ten (10) minutes. Make sure the hydrau-
lic tank is full.
2. Parkmachineonalevelsurfacewiththecuttingunits

limiter is in the transport position to allow full movement
of traction pedal.
3. Read Precautions For Hydraulic Testing in this sec-
tion.
CAUTION
Beforeopening hydraulicsystem,operate allhy-
draulic controls to relieve system pressure and
avoid injury from pressurized hydraulic oil. See

eral Information section of this chapter.
