Remove lower shaft housing alignment set screw, and bolt clamp that connects the lower and upper drive shaft housing. Then remove the 6 star head screws that hold split housing for the drive gears, and carefully split and separate the housing. Remove the broken drive shaft cable. Grease the replacement drive shaft cable full length (very important), and re-grease the drive gears before reassembly. Very quick and easy repair. Just be sure to grease the cable heavily full length, and the coupler that connects the upper and lower cables.
