The current torque specification for the 138-3816 Bolts (1) have been improved to 170 +/- 13 N m (125.4 lb ft) from 150 +/- 15 N m (110.6 lb ft). The 138-3816 Bolts are part of the 125-9358 (2) and 155-5600 Drive Shafts (3) .The new torque specification and yoke thread depth improvement is effective in production on the following machines:
