NOTE 3. Accessories such as generators, starters, fuel and vacuum pumps, etc., previously listed in NOTE 3, are 
satisfactory for continued use with these engines. Such accessories are not integral engine accessories and, 
therefore, are not evaluated for approval during engine certification testing. The airworthiness of such 
accessories is substantiated during aircraft installation system approvals. The suitability of the engine 
mounting provisions as described below must be determined when processing such approvals.

The Hartzell "T" Drive, P/N C-192, weighing 3 lb., is an approved dual-drive unit for installation on the above optional 
engine accessory drives with the following provisions: 
 
Vacuum pump provision (optional)

Hartzell Propeller Co. Installation Instruction No. 2 dated May 4, 1951, explains details for accomplishing 
installation of the C-192 "T" Drive. 
 
NOTE 4. Serial Nos. of engines equipped with dampered crankshafts are suffixed with the letter "D". 
 
NOTE 5. Engines with Serial Nos. below 5122 and those with undampered crankshafts are eligible for takeoff rating of 
only 185 b. hp. at 2300 r.p.m. 
 
NOTE 6. Fuel injection engines previously designated by the letter "J" have been deleted as they are no longer being 
manufactured. Fuel injectors used with these engines do not require a positive fuel head because they will 
draw fuel against an approximately 10-foot head. 
 
NOTE 7. E185-10 is not a production model but denotes E185-3 which has had Bendix Stromberg carburetor replaced 
with Marvel-Schebler MA-4-5. The E185-10 is not interchangeable with E185-3 installationwise, and is 
eligible for takeoff rating of only 185 b. hp. at 2300 r.p.m. 
E-185-11 is identical to E185-8 except for revised mounting brackets. 
E185-8 is identical to E185-1 and E185-9 is identical to E185-3 except for revised starter drive to 
accommodate dog rather than gear type starter. 
Military O-470-7, -7A engines are identical to E185-3. (O-470-7 incorporates provisions for 14 mm. spark 
plugs. When modified to incorporate 18 mm. spark plugs, it is designated as O-470-7A). O-470-B is 
identical to E185-9. These military engines are eligible for use with certificated aircraft and when so used, the 
engine nameplate should be revised to include the corresponding civil model designation and Type 
Certificate No. 
 
NOTE 8. Carburetors of the same model may vary with the aircraft installation. The aircraft specification and /or 
engine manufacturer's manuals contain the carburetor parts list number (on carburetor nameplate) eligible for 
each aircraft installation. 
 
NOTE 9. E185-9 with serial number suffixed by the letter "C" uses Marvel-Schebler MA-4-5 carburetor. These engines 
are not interchangeable, installationwise, with other E185-9 engines, and are eligible for takeoff rating of 
only 185 b. hp. at 2300 r.p.m.

NOTE 10. E-Series engines with the serial number suffixed by the letters "SP" utilize P/N 537733 cylinder. P/N 534895 
piston and P/N 536938 and 536939 piston rings, and are interchangeable, otherwise, with standard engines of 
the same model. 
 
NOTE 11. The following spark plugs and/or those listed in Section 6-4.9 of the latest revision of M-0, Standard Practice
