Which Hydraulic Tests Are Necessary?
Before beginning any hydraulic test, identify if the prob-
lem is related to the traction circuit, lift circuit or steering
circuit. Once the faulty system has been identified, per-
form tests that relate to that circuit.
1. If a traction circuit problem exists, consider perform-
ing one or more of the following tests: Traction Circuit
Relief Valve (R3) and (R4) Pressure, Traction Circuit
Charge Pressure, Gear Pump (P2) Flow, Front Wheel
Motor Efficiency and/or Piston (Traction) Pump Flow
Tests.
2. If a lift circuit problem exists, consider performing
one or more of the following tests: Lift Relief Valve
(SVRV) Pressure, Gear Pump (P1) Flow and/or Lift Cyl-
inder Internal Leakage Tests.
3. If a steeringcircuit problem exists,consider perform-
ing one or more of the f ollowing tests: Steering Relief
Valve (R10) Pressure, Steering Cylinder Internal Leak-
age and/or Gear Pump (P2) Flow Tests.
