1996-1997 ECONOLINE, F SUPER DUTY, F-150-350 SERIES, F-53
Some 1996 and all 1997 E4OD transmissions have been built with a needle bearing located between the forward planetary carrier and forward ring gear hub. This is a revised design for 1997 which was pulled ahead as a running change for 1996. This needle bearing replaces the #10A thrust washer. The slots in the planet carrier for the thrust washer tabs were also removed. The forward ring gear hub was changed to accommodate the needle bearing instead of the thrust washer.
If service is required on the needle bearing, hub or planet assembly, use a new Service Kit (F7TZ-7B067-AB) to service these components. This kit will service all E4OD transmissions. The new design forward planet carrier #10A needle bearing, forward ring gear hub and forward planet assemblies are not interchangeable with the past design components. Refer to the following Service Procedure and Part Application Chart for details.
|NOTE:||IF THE FORWARD PLANET CARRIER HAS SLOTS (FIGURE 1) FOR THE THRUST WASHER TABS, IT DOES NOT HAVE TO BE REPLACED UNLESS IT IS DAMAGED. THE PLANET CARRIER MUST HAVE SLOTS TO BE USED WITH THE #10A THRUST WASHER. EITHER PLANET ASSEMBLY WITH OR WITHOUT SLOTS CAN BE USED WITH THE BEARING.|
Refer to Figure 1 and the Part Application Chart for correct part identification and proper part usage. Follow all normal service procedures as outlined in the appropriate model/year Service Manual, Section 07-01A or appropriate model 1997 Workshop Manual, Section 307-01.
