Description of Change: New roller bearings are now used in the 8E-9034 Planetary Group. The new roller bearing has a segmented cage that is riveted to give longer service life.
Adaptable To: The new 114-3392 Bearing is effective with transmission serial number (1FX1027) and is a direct replacement for the 5P-3488 Race And Roller Assembly in 776C Tractors and 777C Trucks with earlier transmissions. The 114-3392 Bearing can also be used in place of the 5P-3488 Race And Roller Assembly in 776B Tractors and 777B Trucks with 9W-9306 or 3T-0279 Planetary Groups.
The 5P-5044 Outer Bearing Race should be used with the new 114-3392 Bearing.
