The following similarities and diffe rences exist between the various models: O-470-B is similar to O-470-A except for increased power rating, different damper configuration, incorporation of inclined valve cylinders, downdraft pressure carburetor and related induction system changes. O-470-E is same as O-470-A except for incorporation of downdraft pressure carburetor and related induction system changes. O-470-G is similar to O-470-M except for crankshaft da mper configuration, revised oil sump integral cast intake air passage and mounting brackets. O-470-J is same as O-470-A except for reduced rated speed and minor changes in induction system risers, manifold and balance tube. O-470-K is similar to O-470-J except for ratings, cranksha ft damper configuration and incorporation of shell- molded cylinder heads and revised mounting brackets. O-470-L is same as O-470-K except for relocated carburetor and revised intake manifold oil sump. O-470-M is same as O-470-B except for crankshaft damper configuration and incorporation of shell-molded cylinder heads. O-470-N is same as O-470-M except for crankshaft damper configuration. O-470-P is identical to O-470-G except fo r crankshaft damper configuration. IO-470-A is same as O-470-M except incorporates Contin ental continuous flow fuel injection system instead of Bendix carburetor. IO-470-C is same as O-470-G except for crankshaft damper configuration and incorporation of Continental continuous flow fuel injection system instead of Bendix carburetor. O-470-H is same as O-470-B except incorporates extension propeller shaft and is approved for pusher operation. O-470-R is same as O-470-L except for crankshaft damper configuration. O-470-S is same as O-470-R except for piston oil cooling and semi-keystone piston rings. O-470-T is similar to the O-470-S except for crankcase design and rating. O-470-U is similar to the O-470-S except for ra ting and crankshaft damper configuration. Page 5 E-273 NOTE 6. O-470-B, -G, -K, -L, and -M en gines are eligible for incorporation of Continental continuous flow fuel injection system (Eq. No. 5580 for -B, -M; Eq. No. 5701 or 5702 for -G; Eq. No. 5613 for -K, -L) replacing carburetion system with no change in weight. When this modification is accomplished the engines will be designated as O-470-B-CI, O-470-G-CI, O-470-K-CI, O-470-L-CI and O-470-M-CI and the nameplate changed accordingly. NOTE 7. O-470-B engine mounting brackets are eligible for use with O-470-M engines. NOTE 8. O-470-M engines with S/N's suffixed with the le tter “P” are approved for pusher type installation. NOTE 9. Straight mineral or ashless disperant oil meeting Continental Spec. MHS #24 is approved for use in engines, except the O-470-S, -T, and -U which must use ashless disperant oil conforming to MHS-24. Lubricating oils qualified under SAE-J1899 or J1966 are considered qualified under Continental Spec MHS-24 Continental instructions should be followed when changing types of oil. NOTE 10. A full flow oil filter may be used with these engines if the installation incorporates a filter bypass valve which opens between 12 and 16 p.s.i. Oil sump housing is eligible for direct mounting of oil filter having a maximum weight of 6 lb. and overhang moment of 25 in.-lb. NOTE 11.
