Procedure for Piston (Traction) Pump Flow Test
Hydraulic System: Testing
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.
Note: Before performing piston pump flow test, make sure that traction speed
is set to 100% using the InfoCenter settings menu.
Traction circuit flow for the Groundsmaster 4500/4700 is
approximately 113.5 LPM (30 GPM). Use 40 GPM Hydraulic Tester
#AT40002 (pressure and flow) for this test (see
2–16)).
