Number 3 Clutch - Assembly

ASSEMBLY

Special Tools:






NOTE: Apply trans jell or petroleum jelly to all slide portions, rolling contacts surfaces, thrust surfaces etc. to prevent burnout during initial operation. Lubricate O-rings and O-ring seals with MOPAR(R) AS68RC ATF. Soak all friction discs in MOPAR(R) AS68RC ATF for at least two hours before assembly of clutch packs.




Figure 1 - K3 CLUTCH EXPLODED VIEW









1. Lubricate K3 clutch piston seals with MOPAR(R) AS68RC ATF and install the piston into the K3 clutch retainer.





2. Install the K3 clutch piston return spring into the K3 clutch retainer.





3. Lubricate the seals on the K3 clutch balance piston with MOPAR (R) AS68RC ATF and install it into the K3 clutch retainer.










4. Using an arbor press (1) and Compressor tool (2), compress the K3 clutch piston assembly.





5. Install the K3 piston snap ring using snap ring pliers.










6. Remove the K3 piston assembly from the transmission case and install the K3 clutch pack.










7. Install the K3 clutch snap ring.

CLUTCH CLEARANCE AND PISTON TRAVEL COMBINATIONS
























NOTE: If the K3 piston assembly stroke is not within tolerance check the K3 piston seals and the hydraulic fluid circuit path.

8. Install the K3 clutch assembly into the transmission case.
9. Install the 90° Dial Indicator (3) with the SP1917 90° dial indicator tip (1) and mounts from the Dial Indicator Set , being certain the dial indicator tip is positioned into a piston void (2) so that the tip contacts the piston, apply 400 - 500 kPa ( 58 - 72 psi) of air to check the K3 clutch piston stroke clearance. Air Testing Transmission Clutch And Band Operation The K3 clutch piston stroke clearance is 1.60 - 1.85 mm (0.063 - 0.071 in.).










10. Install the K3 clutch pack assembly into the transmission case.

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

11. Install the 90° Dial Indicator and mounts from Dial Indicator Set and apply 400 - 500 kPa (58 - 72 psi) of air to check the K3 clutch pack clearance. Air Testing Transmission Clutch And Band Operation The K3 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 = 6.30 mm (0.248 in.)
- B = 6.45 mm (0.254 in.)
- C = 6.60 mm (0.260 in.)
- D = 6.75 mm (0.266 in.)
- E = 6.90 mm (0.272 in.)
