shaft is kept at a right angle to the machine while the rear is being raised. NOTE: The rear of the machine will need to be raised
24 inches for the shaft to clear the frame with the rear wheel installed.

to pack bearing with grease before installing.

spindle shaft through the lower bearing and steering casting. NOTE: It is important that the shaft goes through the lower bearing
