FLATHEAD Power now includes reproduction transmission covers for ’40 – ’50 Big Twins in its range. Designed to be as authentic as possible, the covers feature copies of the original pieces’ raised cast-on part numbers.
The new covers are cast in 356-T6 aluminum and then CNC machined to provide additional material around the kicker boss for strength and stability. A single bushing is used for complete oiling with a modern small diameter seal hidden after assembly. The covers utilize the stock hardware and filler plug, and a new gasket is included.
Three versions of the cover are available: the J7 cover, which is authentic externally for ’49 – ‘50 Big Twins and has a raised cast-on part number that was authentic from ’48 – ‘50; the G6 cover which duplicates the external shape for ’40 – ‘47, including a stamped-in part number as in the original; and the 00 cover, which has no part number or date code.
