Centrifugal ventilator on back side of has bigger diameter than rotor rink, so motor will not
go out straight, as opening is now wide enough. You needs to rotate it about 30 degrees
to one side in order to get it out. Be careful not to damage spinner, or plastic covers
below spinner.
8. Installation of motor
To install motor back on glider
, follow the reverse order of previous chapter.
Take care about additional steps:
1. Open ventilation fully - knob pushed forward.
2. It is recommended to use new bolt securing plates to secure M8 motor fixation
bolts.
3. Make sure that power cables are connected in the same order as before (check
taken photo for reference), as otherwise motor will not run or it might run in wrong
direction. Use only new complete metal M6 self-locking nuts. Make sure that there is no
contact between cable shoes and aluminum mounting wall or M8 fixing bolts. Air gap
distance between each of these elements and each cable shoe should be at least 3mm.
Below the middle cable, should be placed M8 bolt which has more shallow head (one of 6
bolts which holds motor).
4. Carefully plug in male DB15 connector (with signal wires) into motor rear wall
female connector. Fix connector on both sides with lock springs.
After motor is reinstalled, check that:
•
Spinner is nicely located in the center of the fuselage when spinner is in stop
position. This means that surface of the spinner is as much as possible tangent to
the fuselage contour in area of gap between spinner and fuselage.
•
Gap between spinner and fuselage should be between 0,5-1mm. Gap should be
equal all around (on top should be the same as on bottom side, on left side should
be equal as on right side). If gap is wider than 1mm is not nice.
•
All bolted connections assembled correctly and secured properly. Below six M8 bolts
which hold motor in place are thin brass safety spacers, which needs to be bend 90
degrees against one of the 6 vertical surfaces of M8 hex head bolts.
•
Start the motor on a ground and run it for a few seconds to check:
-that motor rotating direction is counter clockwise (looking in front of the
propeller), and that motor is running smoothly
-that electronic braking of propeller works (above 1500 RPM)
-FCU instrument is functioning properly (check about all functions of the FCU in
its dedicated FCU manual)
