7.3.10 Drivetrain System
Adjustment of the Belts on the Transmission Gear:
Loosen the clamping screw on the left lower side of the transmission gear. Adjust the belt tension (per belt)
by means of the setting screw on the left transmission gear side to 0.15 in. (3.7 mm) press-down depth
halfway between the axes exerting a press-down force of 11.2 lbf. (50 N). Tighten the clamping screws.
Insufficient belt tension is indicated by slipping together with "squeaking" at full power or when the power
lever is pushed forward suddenly.
Removal:
The propeller shaft can be removed together with transmission gear and the propeller in one step:
−
Remove the propeller dome: lift off left and right leg room coverings in the cockpit, Loosen clamping screw
on the stay tube of the propeller dome, pull out locking screw, disconnect flexible hoses, disconnect the
antenna connection to transponder/GPS, withdraw the dome to the front.
−
Disconnect the control cable of the propeller brake on the transmission gear.
−
Loosen four fastening screws on the transmission gear supports, loosen balancing spring on top of the
transmission gear.
−
Pull out transmission gear with propeller shaft.
−
The engine side clutch remains on the engine. Removal by loosening of the attachment screws on the
engine flange.
Installation:
In the opposite order as removal. Attention: Clean and regrease splined sliding joint.
7.4 Landing Gear
7.4.1 Main Landing Gear
Check the main landing gear legs and the trailing arms for deformations and possible cracks as an result of
overloads.
Adjustment Data: see fig. 3.4.1.a
Functional Check:
Support the aircraft (clearance between the main wheels and the ground must be approximately 1.6 in. / 40
mm), remove upper cowling of the central fuselage.
Checking procedure:
−
Inspect screw joints (torque paint);
−
check wheels for smooth turning;
−
joint heads of the operating arms may not be jammed;
−
the articulations of the spindles and the operating arms must have play;
−
installation of the landing gear emergency release system without kinks/collisions;
−
landing gear stop switches on the operating arms: check for halfway position and proper functioning,
inspect wiring / connection;
