Carefully aligned the tail drive shaft using 29/32" wood blocks and a fishing line to assure the drive shaft is straight in the vertical and horizontal. Had to slightly oval the holes in the rear hanger to get the bearing to the proper height. Torqued the bearing hanger bolts. Once the check pilot verifies these are correct I will drill two 1/8" holes through each hanger and mount to index their locations to facilitate future re-alignment.
Installed and torqued the lock nuts on the 12 AN3 bolts that secure the tubing to the bearing.
