gears.  If the gears are too tight, it will cause excessive
strain on the gear box and motor.  If they are too loose,
they will probably strip out after a short period of time.

See figure # 12 below.

Figure # 12

8) To adjust the gear mesh, use a # 1 phillips screw-

driver to remove the three screws holding the front gear
box plate in place.  

See photo # 38 below.

9) Rotate the plate up and out of the way and loosen

the two machine screws that secure the gear box to the
motor.  

See photo # 39 below.

10) Once the screws are loosened you can adjust

the height of the gear box assembly.  When you are satis-
fied with the alignment, tighten the two screws securely
and reinstall the front gear box plate.

11) Double check the gear mesh.  If you are satis-

fied that it is correct, apply a couple of drops of Trinity
bushing oil onto the gear box bearings.  Also apply a light
coating of grease to the gears and rotate the prop shaft a
couple of times to distribute the oil and grease.

12) Remove any excess oil using a paper towel and

reinstall the motor.  Connect the motor leads to the ESC
and reinstall the cowling, propeller and spinner assembly.
