For use with LiteHawk CHARGER XL and CHAMPION
The Motor Coupler Set attaches the Motor Shaft to the Flex Shaft. First attach the two pieces together finger tight, and screw the small hex screw into the side of the motor end of the assembly. Slide the screw on nut end of the assembly onto the Flex Shaft, and the larger nut piece onto the Motor Shaft. Then tighten the hex screw to attach it firmly to the Motor Shaft. Now hold the nut on the Motor Shaft with a wrench or pliers, and tighten nut firmly on the Flex Shaft.
After the 2nd or 3rd time you use your boat. You should lubricate your flex /drive shaft for smooth running and keeping the shaft tube water tight. You will need 2 10mm wrenches. The Champion has a metal double nut coupler with a single grub screw attaching it to the motor shaft. Leave the grub screw alone unless removing the motor.
you need 2 wrenches to loosen the nuts, then totally loosen off the nuts.
Grasp the propeller and carefully pull the shaft out of the coupler, and about 3/4 of the way out of the boat.
Wipe off any old grease, and apply a small dab of axle, or marine grease to the flex shaft and spread it over the length.. it doesn't take very much at all.
Then reassemble in reverse order, fully inserting the shaft back into the coupler and tightening it back up. You should be all ready for you next run!
