7.
Place the propeller on top of the backplate so
that it lines up with the pin, as shown above.
Place a large washer on top of the prop and
then install, using a #4 x 1/2” machine screw.
CAUTION: DO NOT OVER-TIGHTEN, as this
may cause the threads to strip out.
8.
Align the spinner cone with the prop/backplate
and press pins firmly into the holes. One way
to do this is to have the cone pointing down-
ward on a table and press until all pins are
seated.
Install the prop/spinner assembly on the motor
shaft and securely tighten the set screw with a
.050 Allen wrench.
9.
Align the cowl behind the spinner/backplate
assembly, allowing about 1/8” clearance.
Holding the cowl in this position, install #2 x
3/8” sheet metal screws at the cowl mounting
holes.
When finished, remove screws and apply a few
drops of Super Jet™ to “harden” the threaded
wood holes. Open the holes with a pin before
the glue dries.
WARNING:
A SPINNING PROPELLER CAN CAUSE
INJURY. WEAR SAFETY GLASSES AND OPERATE
AWAY FROM SPECTATORS.
