Measure on the intermediate wheel as follows:
7. 1.0 mm is chosen as thickness of the intermediate washer “
III
” as starting point.
8. 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. Punch the inner collar when fitting it to secure that
the two inner collars touch each other.
Measure the intermediate bearing housing for the measures “
D
” and “
E
”.
9. Measure the “
M
” measure for use later on.
10. Calculate the thichness of the intermediate washer “
IV
” now, the intermediate washer = “
C
”
measure minus the sum of “
D
” measure and “
B
” measure.
“
B
” measure is written on the gear-wheel.
11. Measure the “
L
” measure, then calculate the thickness of the intermediate washer “
V
”,
this washer being = “
L
” measure minus the sum of “
E
” measure and the intermediate
washer “
IV
”.
12. Fit the intermediate wheel in the bearings and secure it with a Seeger circlip in accordance
with the drawing for it.
13. Fit the bearing housing with intermediate wheel in the gearbox with O-rings.
14. Remove the end cover in the clutch housing together with the shifting fork arrangement for
the test described in the next point (15) to be carried out.
15. Mount the clamping tools for fixing of the big gear-wheel. Mount a dial indicator on the gear-
wheel of the clutch shaft through the upper opening at the reversing handle of the clutch
housing, so that the indicator meets the following requirements.
a. Point of contact about in the middle of the tooth flank and of the pitch circle.
b. The indicator should be vertical in the longitudinal and height direction of the tooth flank.
With the bigger gear-wheel (z=45) fastened, measure the flank clearance. Measure both
the wheels of the clutch shaft in this way.
If occasion should arise, adjust the clearance to the one stamped which is correct by
changing the washers “
IV
” and “
V
”.
16. Refit the end cover and the reversing arrangement as stated under point 6.
17. Measure the propeller house for “
O
” measure, “
W
” measure and “
U
” measure.
18. Fit the bottom conical gear-wheel marked “
X
” at a torque of
125 Nm±5 Nm (13 ±0.5 Kpm)
on the intermediate shaft of the propeller house.
19. The intermediate washer “
VI
” normally is 1.5 mm and must never be used smaller. Fit the
intermediate washer “VI” on the shaft together with the bearing, the ball filling opening of
which should turn up.
20. Measure the intermediate washer “
VII
” with a feeler gauge and fit the correct thickness
together with the upper locking ring.
