1.11.4
Propeller:
KS-1G-152-R-122-( )-B, attachment bolts: six M 8 x 65 DIN 931 - 8.8, head
with a 2 mm (0.08 in.) dia. hole for lockwiring. Tightening torque of the bolts
- 2-2.5 daNm (15-18 ft lb).
Propeller positioning
(not with optional BBSA friction-centrifugal clutch)
:
To assist in having the propeller stop in a vertical position during flight, the
propeller should be positioned accordingly to the compression point of the
engine. With the propeller in the position for retraction the magneto flywheel
must be in the following position:
x= approx. 20mm (.79in.) with the actuator
directly above the centre of the proximity
switch
Adjustment is made slipping the drive belt
into the required position, see Service Info
69-10 (attached to this manual).
1.11.5
Drive Belt:
Type of drive belt see section 8.1.
Tolerances for drive belt tension and measuring technique: see section 4.12g.
Drive Belt Tensioning:. Tensioning adjustment can be made by turning the
eccentric propeller shaft, see sect. 4.12a.
As an Option a BBSA friction-centrifugal clutch may be installed to reduce
the drive belt loads when starting the engine. The clutch is maintenance free
and constructed as one unit together with the lower pulley and the starter ring
gear. With the clutch the propeller position to the compression point of the
engine will change every engine start, so for aligning the propeller for
retraction a stopper according to drawing 8M234 (enclosed to the MM) is
necessary.
1.11.6
Starter:
Electric starter motor, type see section 8.1.
1.11.7
Ignition system:
a)
Spark plugs; Electrode gap 0.5 mm (o.02 in.). Type see section 8.1.
b)
The electronic boxes (incl. ignition coils) are mounted at the propeller
mount (carbonfibre tower).
1.11.8
Throttle cable connections
The cable can be finely adjusted at the connection point just below the
carburettor. With fully open throttle (butterfly valve vertical) the cable should
be loose. The cable is 1.5 mm diameter Bowden-cable
Friction device for throttle control: This device is located at the control
bellcrank in the instrument panel.
The brake force must be adjusted for a control force of 15-50 N (3-11 lbs.).
