HYDRAULIC SYSTEM
TEST PORTS (Fig. 34,35)
The test ports are used to test pressure in the
hydraulic circuits. Contact your local TORO
Distributor for assistance.
1. Auxiliary Port is located on left side of piston
pump and is used to measure the charge pressure
of the transmission. (Fig. 34)
2. Loosen and remove the Relief Valve and
Swivel Assembly from the Adapter Fitting in left
side of Piston Pump. (Fig. 34)
3. Connect the Pressure Gauge at Adaptor to
check case drain pressure. (Fig. 34)
4. System pressure Test Ports. (Fig. 35)
NOTE: When testing the system pressure
check system at LOAD and NO LOAD
conditions.
PRESSURE SETTINGS:
Operating Pressure 0 - 1500 psi
Case Pressure 1.7 bar (25 psi) max.
Charge Pressure 17.24 to 20.68 bar
(250 to 300 psi)
System Pressure 344 bar (4000 psi)
max. intermittent
207 bar (3000 psi)
continuous rated
The high pressure relief valves used in the MULTI
PRO
®
5500 are all factory preset at 4000 psi and
cannot be readjusted.
GAUGES RECOMMENDED:
System Pressure Gauge 700 bar (5,000 psi)
Charge Pressure Gauge 0 - 50 bar (0 to 500 psi)
Case Pressure Gauge 0 - 25 bar (0 to 100 psi)
