Abstract

The present invention relates to an engine having a crankcase enclosing a transmission assembly including a crankshaft and a clutch member, and a crank torque actuation device (A). The cranking torque actuation device includes at least one driven shaft (311) mounted on a cover having a lubrication path, at least one axially movable ratchet gear (310) mounted on said driven shaft (311), at least one ratchet nut (312), said ratchet nut (312) mounted on the crankshaft (302), at least one oil seal member (313) disposed between the ratchet nut (312) and the driven shaft (311), and at least one idler gear (309) drivingly connecting a drive gear (306) and the ratchet gear (310). Said ratchet gear (310) rotates about an axis of driven shaft (311) with a predetermined movement to engage with a complementary shaped ratchet portion (312a).
