Tools Required
-
J 24171-A Seal and Dust Shield Remover
-
J 43782 Rear Seal Installer
Removal Procedure
1. Remove the yoke assembly from the transmission.
2. Obtain J24171-A and install a 90 degree hook onto the end of the slide-hammer (1).
3. Position the 90 degree hook behind the rear face of the seal's outer case (2).
4. Remove the rear seal using the slide-hammer.
5. Inspect the seal bore for scratches. Remove any scratches in the seal bore using crocus cloth.
Installation Procedure
Important: Be sure the new seal has blue sealant coating the OD (4). This identifies the seal for use in the 1000 Series transmissions. The blue
sealant identification is important because the 1000 Series transmissions have an overdrive ratio in fifth range and there is a potential for high output
shaft speeds and resultant high seal temperature.
1. Align the seal so the seal lip (2) is outward and the face of the steel case (1) will be against the driving face (3) of the tool. Install the new seal onto
J43782.
