The "M" center crank uses all the design features of the "M" side crank. The addition of another crank web enables the use of two more ball bearings for better load distribution.

The most noticeable feature of the "M" center crank is that power can be taken from both ends, allowing for close-in use of power take-off for auxiliaries.

The engine shares most parts with the "M" side crank, with an additional crank disk, two additional main bearings on the crankshaft, and a different base. Ready to run price is $3,800.
