Procedure for Piston (Traction) Pump Flow Test
This test measures piston (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-
masterisapproximately30 GPM(113.5LPM).Use 40
GPMHydraulicTester#AT40002 (pressureandflow)
for this test (see Special Tools in this chapter).

the parkingbrake. Makesure mowspeed limiteris inthe
transport positionto allow fullmovement of traction ped-
al.
2. Read Precautions For Hydraulic Testing in this sec-
tion.
CAUTION
Before opening hydraulic system, operateall hy-
draulic controls to relieve system pressure and
avoid injury from pressurized h ydraulic oil. See
Relieving Hydraulic System Pressure in the Gen-
eral Information section of this chapter.
3. Make sure that traction pedal is adjusted to the neu-
tral position. Also, ensure that piston (traction) pump is
at full stroke when traction pedal is pushed into fully for-
ward position.
4. Raise and support machine so all wheels are off the
ground (see Jacking Instructions in Chapter 1 - Safety).
