A new 112-9938 Sleeve Bearing is available for parts service replacement of the 3T-0052 Sleeve Bearing (part of the balance piston assembly for the No.2 clutch). The new 112-9938 Sleeve Bearing does not require sizing after installation. See the reference article. The 112-9938 Sleeve Bearing can be used in place of the 3T-0052 Sleeve Bearing in all applications.

The 112-9938 Sleeve Bearing will require less time to install since it does not have to be burnished to size after installation.

NOTE: The 112-9938 Sleeve bearing is for parts service only. Use of the 3T-0052 Sleeve Bearing continues in production.
