Inspection Of Bendix Gear - Magni Gyro M16C Ordinary Maintenance Manual

M16 (C) TANDEM TRAINER
MAINTENANCE MANUAL
14. Make sure the rotor brake lever pn 199 is in OFF position (low);
15. Make sure that the sheath pn 131 of the rotor brake cable is positioned correctly in the seat of the rotor
brake lever pn 199;
16. Insert the rotor brake cable pn 1,5x3.900 along the sheath retainer pn 200;
17. Insert the rotor brake cable pn 1,5x3.900 in the clamp pn 202 of the brake lever pn 201;
18. Tighten the clamp pn 202;
WARNING:
The lever pn 201 must not travel more than 20 mm.
19. Insert the flexible cable pn 118 and the sheath pn 119 into the rotor head couplings pn 039 and pn 040;
20. Screw the two bolts pn M6x16 that fix the sheath pn 119 to the connection pn 039. Thereby respect the
position of the four split washers 6x12 and two plane washers 6x12;
21. Operate the bolt pn M6x20 placed on top of the coupling gear GR03 and turn this gear clockwise, so as to
insert the flexible cable pn 119 more easily in its seats;
22. Following the instructions of paragraph 3.7 CONTROLS FRICTIONING, either tighten or release the bolts
pn NAS 628 52 and NAS 628 30 to check that the frictioning of the controls is correct;
23. Place the safety pin pn AN416‐1 on the bolt NAS 628 52.
3.6 INSPECTION OF BENDIX GEAR
(See Fig. 3.6/1 ‐ 3‐6/3)
The Bendix coupling gear GR03 together with the notched gear pn 061 are the last link of the pre‐rotation chain.
The Bendix gear has its seat in the fork's tube pn 046, where it can slide and engage the notched gear pn 061 to
transmit the movement of the flexible shaft.
A failure of the Bendix unit GR03 can cause a bad or no functioning at all of the pre‐rotation system. In this case,
the operator can apply to the nearest maintenance centre or otherwise execute the following inspections, while
strictly following the described procedure.
3.6.1 REMOVAL OF BENDIX GEAR
(See Fig. 3.6/1 ‐ 3‐6/3)
1. Make sure that the master switch is in OFF position and that all the breakers are switched OFF;
2. Remove the two bolts M6x16 that fix the flexible shaft's sheath pn 119 to the containment cup pn 039;
3. Keeping the control stick (2) in forward position, extract the sheath pn 119 and with it the flexible shaft
pn 118 from its square section ending on the splined shaft pn 040;
4. Still keeping the control stick (2) in forward position, remove the three bolts M5x12 that fix the cup pn
039 to the fork pn 046;
5. Gently beat the Bendix coupling gear pn 045 with a rubber hammer, extract the assembly GR03; (Bendix)
from the lower part of the tube of the fork pn 046;
3.6.2 INSPECTION OF BENDIX GEAR
(See Fig. 3.6/1 ‐ 3‐6/3)
1. Manually check the correct sliding of the gear pn 045 along the shaft pn 040. The gear must slide along
the shaft while rotating, without hindrance;
2. Remove the excess of grease from the Bendix gear pn 045 and, clean it with gasoline or diluents;
3. Extract the coupling gear pn 045 from the worm screw pn 044;
