d)
Initial setting of eccentric axis 8M115
If the marking was lost or if a new axis is to be installed, the eccentric
must be positioned as follows:
Remove the sealing cap 8M118/1.
The groove in the front end of the axis shall point downwards. This is
the lowest position of the eccentric. From this position rotate the axis in
a clockwise direction (see a) 5.) from 1 mounting hole to the next and
fix the axis min. 2 bolts in each position to check the drive belt
tensioning. Proceed until the correct tensioning is reached.
During this the axis should not be rotated more than 180° (groove in
upper position). However it should be impossible to reach this position.
e)
Reassembly
1. Reassembly is the reverse of disassembly. Use Loctite 243 to secure
all screws and bolts except for the propeller mounting bolts.
Caution: When reassembling the drive belt covers be careful to use
the correct screws. Screws which are too long will damage the belt!
2.
If the position of the axis has been changed the fork 8M119 must be
brought to vertical position again. Screw out the fork (axis already
assembled with all 6 bolts). Loosen the distance washer 23 x 32 x 1
from the axis 8M115. Apply a suitable 2 component metal adhesive
(e.g. UHU Plus 300) between 8M115 and the washer. Screw in the
fork 8M119 again using Loctite 243 for securing until the fork is in
vertical position. The glue should be pressed together to less than 1
mm thickness. Let the glue cure before operating the engine.
3.
Adjust and secure the proximity switch according to sect. 1.14.15.
f)
Changing the relation of propeller to engine
see section 1.11.4
Adjustment is made slipping the drive belt into the required position,
see also Service Info 69-10 (attached to this manual).
