Oil Pressure Readings - NS

[Paccool]

I have a Cummins Operation and maintenance manual for B series engines. For a 160 HP B5.9 used for automotive use:

Minimum allowable pressure at idle = 10 PSI
Minimum allowable pressure at rated RPM = 30PSI
Regulated pressure = 65 PSI

"Regulated pressure" is the pressure the bypass spring opens up and puts oil back into the crankcase. This should be the highest pressure you see on a gauge.

BTW, the manual was printed in 93 but the engines are the same basic engine from 89 to 93. Shows 5 different HP engines from the 160 HP the way up to 230 HP and the oil pressures are all the same.
