Holding Clutch - Description

DESCRIPTION




Figure 1 - ORIENTATION OF CLUTCHES





The B1 and the B2 brake clutch (holding clutch) assemblies used in the AS68RC transmission are all friction clutches anchored to the transmission case. Brake assemblies are used to hold and prevent rotation of specific components of the P1, P2, P3, planetary gear sets to transmit drive torque.




Figure 2 - B1 BRAKE CLUTCH





NOTE: The selectable clutch pack reaction plates are identified by an alpha numeric numeral stamped into the face of the plate.

The B1 brake piston stroke clearance is 1.55 - 1.80 mm (0.061 - 0.71 in.)

The B1 brake clutch pack clearance is 1.25 - 1.50 mm (0.049 -0.059 in.). If the clearance is not within tolerance, choose the correct selectable reaction plate.

- A = 5.40 mm (0.212 in.)
- B = 5.55 mm (0.218 in.)
- C = 5.70 mm (0.224 in.)
- D = 5.85 mm (0.230 in.)
- E = 6.0 mm (0.236 in.)




Figure 3 - B2 BRAKE CLUTCH





NOTE: The selectable clutch pack reaction plates are identified by an alpha numeric numeral stamped into the face of the plate.

The B2 brake piston stroke clearance is 1.84 - 2.28 mm (0.072 -0.090 in.).

The B2 brake clutch pack clearance is 1.60 - 2.04 mm (0.063 -0.080 in.). If the clearance is not within tolerance, choose the correct selectable reaction plate.

- A = 5.40 mm (0.212 in.)
- B = 5.60 mm (0.220 in.)
- C = 5.80 mm (0.228 in.)
- D = 6.00 mm (0.236 in.)
