Tests
6. To monitor pump delivery pressure, use the pressure
gauge on flow meter. As an alternative, use the laptop
computer with excavator diagnostics program (See the
installation procedure in this group.), the digital
pressure and temperature analyzer with transducers, or
gauges. For the analyzer or gauges install adapter (A)
and male quick couples to test port in pump housing,
7. Install the temperature probe on the hydraulic
tank-to-pump suction line. (See JT05800 Digital
Thermometer Installation in this group.)
8. Use the laptop computer with excavator diagnostics
program to monitor engine speed or install a
tachometer. (See JT05801 Clamp-On Electronic
Tachometer Installation in this group.)
9. Check that the flow meter loading valve is open.
10. Heat the hydraulic oil to the specified temperature by
closing flow meter loading valve to increase pressure
to approximately 20 685 kPa (207 bar) (3000 psi).
