150 LPM (40 GPM) Hydraulic Tester
K line Part No. AT40002
Use this tester to test the hydraulic circuits
and components for flow and pressure
capacities. The tester flow measurement
maximum is 151 LPM (40 GPM). This
tester includes the following:
Load Valve – Turn the valve to restrict the
flow to create a simulated working load in
the circuit.
Pressure Gauge – A glycerine filled
pressure gauge 0 to 34,500 kPa (0 to
5,000 psi) to provide operating circuit
pressure.
Flow Meter – This meter measures the
actual fluid flow in the operating circuit
with a gauge rated at 20 to 150 LPM (4
to 40 GPM).
Note: This tester does not include
any hydraulic hoses or fittings; refer
to Hydraulic Hose Kit K Line Part No.
TOR6007 and Hydraulic Test Fitting Kit K
Line Part No. TOR4079.
Traction Circuit Hydraulic Diagnostic Fittings
K line Part No. 59-7410
To measure traction charge pressure,
reverse traction circuit reducing valve
pressure or rear traction circuit relief valve
pressure, a diagnostic fitting is required.
To measure reverse traction relief
pressure, two (2) fittings and a diagnostic
test fitting are needed. The fittings can be
temporarily installed into the appropriate
component port to allow pressures to be
measured. Refer to the Testing section of
this chapter for necessary test procedures
when using these diagnostic fittings.
