Technical data

An oil filler screw with dipstick and an oil drain plug are screwed into the gear casing. The filler
screw is provided with a breather hole.
The shaft for actuating the multiple-disc clutch extends through a cover on the side of the gear casing.
3. GEAR SETS
The transmission is equipped with shaved, casehardened helical gears made of forged low-carbon
alloy steel. The multi-spline driving shaft connecting the transmission with the engine is hardened as
well.
The driven shaft (propeller side) of the transmission is fitted with a forged coupling flange, except on
the V-drive model.
4. MULTIPLE-DISC CLUTCH INCLUDING OPERATION - POWER TRAIN
The engine torque is applied to the input shaft (36) in the specified direction of rotation and, IN
SHIFTING POSITION A (forward), via gear (44), the frictionally engaged clutch discs (51 and 52) to the
external disc carrier (57) and from there via the guide sleeve (59) to the output shaft (66).
IN SHIFTING POSITION B (reverse), the torque is transmitted from the input shaft (36) via intermediate
gear (26), gear (65), clutch discs (51 and 52) to the external disc carrier (57), the guide sleeve (59) and the
output shaft (66).
