Brief Description: Mounted Main Sprocket to Rotor Mast
Purchased one ton chain hoist and mounted to workshop joist. Followed Pro-Drive instructions for raising main mast. Mounted main sprocket to mast and lowered into place. Achieved 1/4" space between bottom of main sprocket and the square drive tubes. John Spurling said that was fine since we won't need additional clearance for the oil chain bath. Used spirit level to measure for John to mill the secondary unit where it mates to the square drive tube. The aft square drive tube was 89.7 degrees in relation to the top of the main sprocket. This information faxed to John S.
