Which Hydraulic Tests Are Necessary?
Before beginning any hydraulic test, identify if the prob-
lemisrelatedtothetractioncircuit,cutting(mow)circuit,
lift circuit or steering circuit. Once the faulty system has
been identified, perform tests that relate to that circuit.
1. If a tractioncircuit problem exists, consider perform-
ing one or more of the following tests: Traction Circuit
ReliefPressure,TractionCircuitChargePressure,Gear
Pump (P3) Flow, Wheel Motor Efficiency and/or Piston
(Traction) Pump Flow Tests.
2. If a cutting (mow) circuit problem exists, consider
performing one or more of the following tests: Relief
Valve(R1)and(R2)Pressure,GearPump(P1)and(P2)
Flow,ReelDriveMotorEfficiencyand/orReelDriveMo-
tor Cross--Over Relief Pressure (Reelmaster 5510 and
5610) Tests.
3. If a lift circuit problem exists, consider performing
one or more of the following tests: Lift Relief Valve (R6)
Pressure, Gear Pump (P4) Flow and/or Lift Cylinder In-
ternal Leakage Tests.
4. Ifas teeringcircuitproblemexists,considerperform-
ing one or more of the following tests: Steering Relief
Valve (R10) Pressure, Steering Cylinder Internal Leak-
age and/or Gear Pump (P3) Flow Tests.
