gears 44R and 48L.

driven shaft (C) is transferred to the reduction gear (D) by way of the
connecting shaft (B) to provide forward force.

32L (E). The rotation is reversed by this gear and transferred to the reverse
gear (E). The rotation of the driven shaft (C) is transferred to the reduction gear
(D) by way of gear 48L and the connecting shaft (B), to reverse gear (E).
