Page 247: Gear Ratio
Gear Ratio The BW7 gear which is used on DV24 has normally a reduction ratio of 3.0:1 for AHEAD and 2.36:1 for REVERSE. For special purposes it can be delivered with a reduction ratio of 2.47:1 for AHEAD and 2.36:1 for REVERSE. Oil Change The gear will need no other attendance than regular change of oil. - Page 248 009W2229-R01...

Page 285: Assembling Procedure For Sail Drive
Assembling Procedure for Sail Drive Measure the intermediate piece (between engine and clutch housing), the clutch housing and the end cover for the same, and then the “K” measure can be worked out. Up-end the clutch shaft so that any clearance is equalized. (about 2 kg compression, if it is not possible to up-end the shaft). - Page 286 Measure on the intermediate wheel as follows: 1.0 mm is chosen as thickness of the intermediate washer “III” as starting point. Freeze the gear-wheel and measure the stagger between the inner collar and outer collar of the bearing. Fit the bearing with the ball filler hole facing the adjusting washer “IV”. Fit the next bearing correspondingly.
