21. Calculate the “ T ” measure. The “ S ” measure is stamped on the gear-wheel whereas the
“ R ” measure has to measure. “ T ” measure = “ S ” measure minus “ R ” measure.
22. The intermediate washer ” VIII
B
” should be: the sum of “ T ” measure and “ Q ” measure
minus the difference of “ U ” measure and “ O ” measure.
23. Find the thickness of the intermediate washer “ VIII
A
” by measuring the bearing outer collar
“ N ” measure, after which the washer should be: the sum of “ M ” measure and “ O ” measure
minus the sum of intermediate washer “ VIII
B
” and “ N ” measure.
24. Having finished the measuring of the intermediate shaft remove the gear-wheel marked
“ X ” again and fit the needle bearings “ Z ” and “ Y ” after the house has been heated.
25. Fit the intermediate shaft with bearings in the propeller housing.
26. Refit the gear-wheel marked “ X ” and tighten it with the same torque as indicated in point
18.
27. Check whether the distance measures of the small gear-wheel are correctly adjusted with
the fitted washers (“ T ” measure) with special tools.
28. Measure the “ V ” measure.
29. Heat the bearing housing “ Æ ” and fit the bearing with the ball filling opening facing the
gear-wheel side.
30. Measure the thickness of the washer “ X ” with a feeler gauge (between locking ring and
outer collar of the bearing ).
31. Calculate the intermediate washer “ IX ”. The “ W
1
” measure is indicated on the gear-wheel.
The intermediate washer = “ W ” measure minus the sum of “ V ” measure and “ W
1
” measure.
32. Fit the output shaft with gear-wheel in the cover for propeller house with seals.
33. Fit cover with shaft and gear-wheel in the propeller housing.
34. Check the flank clearance at the output shaft.
The intermediate shaft is blocked and on the propeller shaft a lever is placed, on which
should be measured at difference radius R=40 mm. The shaft nut must be tightened.
The correct flank clearance is indicated on the gear-wheel and is corrected at the
intermediate washer “IX” if necessary.
On pages S10, S11, S12 and S13 longitudinal sections of the sail drive with places of measuring
drawn in are shown, partly by a general drawing and partly by detail drawings.
