Assembling Procedure for Sail Drive
1. 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.
2. 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). At the same time the gear-wheel should be engaged.
Measure the “J” measure now. Measure the “
C
” measure for use later on under point 10.
3. Measure the “
H
” measure in order to find the centre of the vertical intermediate shaft.
Measure the “
G
” measure as “
F
” m “
A
” measure, as the “
A
” measure is written on
the gear-wheel.
Measure the “
F
” measure while the shaft still stands on its edge, so that any clearance is
equalized.
Calculate the thickness of the intermediate washer “
II
v
” as: “
H
” measure minus “
G
” measure.
4. Calculate the thickness of the intermediate washer “
II
r
” as: “
K
” measure minus sum of “
J
”
measure and intermediate washer “
II
v
”.
5. Fit the intermediate piece on the clutch housing with liquid jointing as filling piece.
6. Fit the reversing part at the top of the clutch housing as follows:
a. Put the reversing lever in “Neutral” position and the pipe collar too.
b. Lead the reversing house with gasket into the opening of the clutch housing and press the
shifting eccentric into the wedge-shaped groove of the shifting fork. In order to equalize the
axial clearance between the shifting fork and the pipe collar the shifting eccentric should be
fitted with the groove in the shifting fork with a light pressure.
c. Tighten the reversing house in this position.
NOTE: The clearance of the angle between the longitudinal shaft of the gear and the
one of the reversing lever must be observed. The angle is to be
90°±30`
.
Use a reference gauge for this purpose.
When adjusting the reversing house the fixing screws must not encounter the wall of the
slots of the reversing house as this would lead to wrong adjustment.
d. Shift the reversing lever in both directions and test the shifting function. In both shifting
positions the pipe collar be connected (click), when the angles of engagement measured
on the reversing lever are as equal as possible.
Besides, it must always be possible to turn the reversing lever
37°
. The adjustment is
corrected by axial displacement of the reversing house, the angle of 90° being observed.
e. In order to test the function of both clutches turn the input shaft (clutch shaft) round by hand
and brake the output shaft by hand when engaged.
The upper part of the sail drive is now temporarily ready.
