(b) During testing, do not exceed a pump speed of 4200 rpm; performance capacity at this speed is 0.3
gpm. A 1/10 horsepower motor is required to operate the oil pump under the following conditions: 130 psi oil pressure;
3750 rpm; temperature, 21C (70F).
(c) With pump running at 3750 rpm, increase oil pressure slowly until relief valve by-passes to inlet port.
The pressure at this point should be between 90 and 110 psi gage. If this pressure limit is not obtained, unscrew inlet
elbow (16) and rotate spring retainer (17) to obtain the proper by-pass pressure. After final adjustment of spring retainer,
stake retainer to pump body (8) to secure retainer in adjusted position.
(d) Pump capacity at 3750 rpm and at a minimum of 100 psig oil pressure should check out at a
minimum oil flow of 525 25 cc per minute.
(e) Check for leakage at shaft seal end opposite mounting pad. If any leakage is noted at this location,
replace seal J2) and/or preformed packing O-rings (13). Before installing new seal, inspect that the seal is free of nicks.
(f) After testing, seal oil pump ports and rear end of shaft with tape to exclude dirt.
(g) Oil sump does not require testing. When oil sump is attached to crankcase on final assembly, fill it
with oil to specification FSN 9150-753-4667, FSN 9150-75-4667 4667.
f. Motor
(1) Refer to figure 6-5 and reassemble in reverse order of disassembly except as follows:
(a) Press plug (61) into gearshaft (60).
(b) Pack ball bearings (63) with grease Specification MIL-G-6118 and press bearings on each gearshaft
(62). Position each bearing so that its flush side
