New Bearing Race Is Used On The Auxiliary Drive
Usage:
3408 And 3412 Engines Equipped With Auxiliary Drive Units
Description of Change: A new outer race is used on the roller bearing of the auxiliary fan drive unit. The new outer race provides additional clearance for expansion of the inner race at assembly. The additional clearance provided by the new outer race will prevent binding and increase the service life of the bearing.
Adaptable As: The new 8T209 Race is a direct replacement for the 6V6570 Race. Only the outer race of the 4M6107 Bearing has changed.
