properly adjusted (see 22.214.171.124).
126.96.36.199 Alternator system. The engine alternator system shall deliver 28 volt (V) direct
current (dc), providing not less than 60 amperes (A) for charging and operating loads. The drive
ratio shall be such that at a normal engine idle, the electrical output shall be not less than 18 A.
The alternator shall conform to Drawing 10929868 and MIL-PRF-46795 (see 188.8.131.52.1).
184.108.40.206 Starting system. The engine starter shall be a 24 V electric solenoid actuated,

220.127.116.11 Air compressor. The air compressor on the engine with applicable governor
shall deliver the following minimum air flows at a pressure of 125 pounds per square inch gage
(psig) [862 kilopascals (kPa)] at the specified engine speeds (see 18.104.22.168.3).
a. 5.4 ft3/min (153L/min) at an air density of 0.073 lb/ft3 (1.17 kg/m3) at engine full
load governed speed (2100 rpm).
b. 4.2 ft3/min (119L/min) at an air density of 0.073 lb/ft3 (1.17 kg/m3 ) at 1500 rpm.
In addition, the unloading valve shall function properly in conjunction with air
compressor governor at normal governing pressure. Air flow performance shall
be conducted at (or corrected to) an ambient intake air temperature of 77 +5°F
(25±3°C) and dry barometer pressure of 29.42 +0.5 in. of Hg.(2981 ±51 kPa).
22.214.171.124 Engine governor. The engine speed shall be limited to speeds of not more than
2450 rpm, no load, by means of a tamper-proof governor. The governor shall be set as specified
herein and sealed during the break-in run (see 126.96.36.199.4).
188.8.131.52 Power steering pump. The engine shall be equipped with a power steering pump
conforming to Drawing 11664247. The power steering pump shall be filled with 10W oil in
ambient temperatures between -10 and +120 degrees Fahrenheit (°F) [(-23 and 49 degrees Celsius
(°C)] and arctic oil in temperatures between -65 and 0°F (-54 and -17°C). The pump assembly
shall conform to Drawing 11664481 (see 184.108.40.206.5).
220.127.116.11 Electromagnetic interface. Unless otherwise specified (see 6.2), the engine and
