2. Remove multiple-disc pack B3 (133) and spring washer (133b) by removing snap ring (133a) in transmission housing
- To facilitate removal of the snap ring (133a), compress the multiple-disc pack B3 (133)
- Check multiple-discs for scorch marks and wear
3. Unscrew Torx socket bolts (11)
4. Remove multiple-disc brake B2 (14) from transmission housing
- The outer multiple-disc carrier for multiple-disc brake/B2 also serves as the piston for the multi-disc brake/B3
5. Remove parking lock gear (15)

ASSEMBLY
1. Insert parking lock gear (15)
2. Install multiple-disc brake B2 (14) in transmission housing (2)
3. Screw in Torx socket bolts (11) and tighten to: 16 Nm
4. Insert and measure disc spring (133b) and multiple-disc pack B3 (133) as follows:
a. Refer to Survey of multiply-disc components to locate correct number of discs for this application. Application and ID
b. Observe outer multiple-disc sequence of installation, then procedures as follows:





c. Place discs for multiple-disc brake B3 together in the sequence shown in the illustration above
- Place discs individually
d. Using a feeler gauge, determine the play "L" at three points between the snap ring (133a) and the outer disc (133c)
- During the measurement the snap ring (133a) must contact the upper bearing surface of the groove in the disc carrier

Adjustment Values Multiple Disc Brake B3
