4.2 Immediately stop a centrifugal chargihg pump if any of the following occur:
- Oil leaving thrust bearing exceeds 160*F.
- Sudden drop in discharge pressyre.
- Loss of component cooling watWh to a running pump.
- Lube oil pressure drops to zero.
4.3 Ir .iately stop the positive displacement pump if any of the f: owing occur:
- Pump bearing oil temperature reaches 180*F.
- Gyrol fluid drive temperature reaches 220*F.
- Pump nearing oil pressure drops to 7.ero.
- Gyrol fluid level falls below 1/4 in sightglass.
