Special Tools

Order these tools from your Toro Distributor.
Hydraulic Pressure Test Kit - - TOR47009
Use to take various pressure readings for diagnostic
tests. Quick disconnect fittings provided attach directly
to mating fittings on machine test ports without tools. A
high pressure hose is provided for remote readings.
Contains one each: 1000 PSI (70 Bar), 5000 PSI (350
Bar) and 10000 PSI (700 Bar) gauges. Use gauges as
recommended in Testing section of this chapter.
Hydraulic Tester (Pressure and Flow) - - TOR214678
This tester requires O--ring Face Seal (ORFS) adapter
fittings for use on this machine.
1. INLET HOSE: Hose connected from the system cir-
cuit to the inlet side of the hydraulic tester.
2. LOAD VALVE: A simulated working load is created
in the circuit by turning the valve to restrict flow.
3. LOW PRESSURE GAUGE: Low range gauge to pro-
vide accurate reading at low pressure: 0 to 1000 PSI.
A protector valve cuts out when pressure is about to
exceed the normal range for the gauge. The cutout
pressure is adjustable.

4. HIGH PRESSURE GAUGE: High range gauge
which accommodates pressures beyond the capacity of
the low pressure gauge: 0 to 5,000 PSI.
5. FLOW METER: This meter measures actual oil flow
in the operating circuit with a gauge rated at 15 GPM.
6. OUTLET HOSE: A hose from the outlet side of the
hydraulic tester connects to the hydraulic system circuit.
