Note 1:
When you tighten the collar (
H0121-S
) on
the main shaft, ensure there is no axial play. Push
down the main shaft while pulling up the locking
collar. Tighten the screw
M4x22
at this time.
Note 2:
The pinion and gear are designed to have zero
backlash. This leads to initial “rough” rotation.
After some run in flights (
3-5 flights
) it will begin
to rotate freely, ensuring perfect contact and
the ability to transmit maximum power.
It is advisable to lubricate these two elements
with a lubricant ( Tri-Flow Synthetic grease).
