- Install race nut in housing and tighten securely. Install Allen head race nut set screw through housing and tighten. Place piston on bench with ball guide holes facing up.
- Insert worm shaft into piston so that the first groove is in line with the hole nearest the center of the piston. Place the ball guide in the piston. Place a minimum of 27 ball bearings in the ball guide while turning worm counterclockwise as viewed from input end of shaft.
- If all balls have not been fed into the guide upon reaching the left stop, rotate the input shaft in one direction and then the other while inserting the remaining balls. DO NOT rotate the input shaft more than 3 turns from the left stop or the balls will fall out of the circuit.
