All C9HE2 except the 982C9HE2 and 989C9HE2 models are similar to the corresponding C9HE1 models except for the incorporation of a built-in torquemeter at an additional weight of 10 lbs. The 989C9HE2 engine is similar to the 989C9HE1 model except for the incorporation of a generator drive. The 982C9HE2 engine is similar to the 98C9HE1 model except for ignition timing, ratings and fuel grade. The 982C9HE-315 is similar to 982C9HE2 except for the incorporation of a built-in torquementer at an additional weight of approximately 10 lbs. NOTE 5. Special takeoff ratings are eligible on the following models as specified: Models T.O. RATINGS (hp, rpm, in. Hg., ft.) 955C9HE1 & 2 960C9HE1 & 2 1525-2800-51.5-2500) With anti-detonant injection 967C9HE1 & 2 1525-2800-52.0-S.L.) fluid consumption 5#/min. 959C9HE1 & 2 1525-2800-56.0-700 (dry) 963C9HE1 & 2 1525-2800-56.0-S.L. (dry) Engines with wet (AD1) ratings incorporate a water injection regulator and utilize AMS-3006 or equivalent fluid which is composed of 25% Methyl alcohol, 25% Ethyl alcohol in accordance with AM-A-24 requirements and 50% water. NOTE 6. The Military R-1820-80 is identical to the 968C9HE1 model and is eligible for use in certificated aircraft and when so used, the engine nameplate should be revised to include the corresponding civil model designation and Type Certificate No. Magneto model designation is Bosch S9LU. NOTE 7. The 989C9HE1 & 2 engines are approved for helicopter application and operation in a 34° nose up and 8° clockwise roll attitude. NOTE 8. The 989C9HE1 & 2 engines are eligible for operation with grade 100/130 fuel at the following ratings: Maximum continuous hp, rpm, in. Hg. at: Critical pressure altitude (ft.) 1275-2500-46.0-3500 Sea level pressure altitude 1275-2500-47.5-S.L. Takeoff (Five min.) hp, rpm, in. Hg. at: Critical pressure altitude (ft.) 1425-2800-52.0-2900 Sea level pressure altitude 1425-2800-53.0-S.L. 5 E-259 NOTE 9. The ratings of 982 and 989C9HE1 & 2 engines are based on standard conditions of temperatures and barometric pressure (60°F and 29.92 in. Hg. at sea level) and 0% humidity. A correction equal to twice the actual vapor pressure may be added to the allowable take-off MAP. When setting take-off power for torquementer equipped 982C9HE3 engine, observe maximum limits of 340 psi torque/229BMEA or 54.5 in. MAP plus vapor correction, whichever occurs first. NOTE 10. The Military R-1820-82 and -82B may be identified as Model 982C9HE2 when inspected and overhauled according to Wright Service Bulletin No. C9-473 dated December 14, 1979, and the 982C9HE2/NAVAIR instruction and parts manuals listed therein. Upon completion the engine nameplate is to be modified to specify 982C9HE2 and T.C. E-259. .....END.....
