Check
1
Remove the lock of the spherical terminal (2) and disengage the rod of the pneumatic cylinder (1) drive of the motor brake
Apply resistant grease at high temperatures.
2
Test flap shaft movement smoothness
3
Examine air cylinder (1), joint part and flap shaft for wear
4
Check the firm attachment of the lever to the grooved end of the throttle
5
Adjust the pre-tensioning (D) of the pneumatic cylinder mounting
This measurement will be correctly adjusted when air cylinder rod is pulled according to correspondent measurement.
The pre-tensioning eliminates the vibrations caused by the throttle valve, thus avoiding the premature wear of the motor brake assembly.
