 +====== Oil Pump Pressure (57-85) ======
 +Engine oil pressure was measured (by the MoCo) with a pressure gauge at the oil pump. \\ 
 +Expected oil pump pressure per FSM's: \\
 +
 +**Gauge mounted at oil pump**: \\
 +
 +As checked with hot oil and a gauge at the oil pressure switch location at the oil pump. \\
 +The oil pressure switch has to be removed for the gauge to be installed. \\
 +
 +**1957-1969**:​ ((1959-1969 HD FSM pgs 3A-11, 3A-15)) \\
 +Minimum: 3-7 psi (idle, with spark retarded) \\
 +Normal riding conditions: 10-14 psi (6 psi at 20 mph) \\
 +
 +**1970-1978**:​ ((HD 70-78 FSM pgs 3-1, 3-5)) \\
 +Minimum: 3-7 psi (idle) \\
 +Maximum: 15 psi (60 mph in high gear) \\
 +Normal riding conditions: 4-15 psi
 +
 +**1979-1985**:​ ((1979-1985 HD FSM pgs 3-1, 3-10)) \\
 +Minimum: 4-7 psi (idle) \\
 +Maximum: 10-20 psi (3500 rpm) \\
 +Normal riding conditions: 4-15 psi \\
 +
 +**Note**: On a cold startup, expect pressure to reach ~60 psi ((IronMick of the XLFORUM http://​xlforum.net/​forums/​showthread.php?​t=1456449)) \\
