307-01-83 Automatic Transmission 307-01-83 ASSEMBLY (Continued) 5. Align the C3 piston in the cylinder until the OD of C3 Clutch, Reverse Sun Gear & the piston enters the inside diameter of the Forward Sun Gear Assembly cylinder. Ensure that the piston ‘O’ ring compression is adequate but not excessive. Special Tool(s) Assemble the spring and spring retainer on the piston. Using tool 307-369 compress the spring Clutch Compression Kit sufficiently to enable the installation of the retaining circlip. Ensure that the circlip is firmly seated in the groove and remove the tool. Fit the C3 wave plate to the C3 piston face with one crest of the wave plate directly over one of the piston orifices. Assemble the clutch plates and discs into the cylinder in the following sequence: Clutch Measuring Kit

8. Friction disc inner. Align and fit the pressure plate with the counterbore facing away from the clutch plates. Install the circlip. 6. Check the clutch clearance using special tool 307-370 in the following manner: Forward sun gear and C3 clutch assembly 1. Check the orifices in the cylinder are clear. Check the C3 cylinder bush outside diameter against the centre support inside diameter. Coat the sealing rings with automatic transmission fluid and fit into the C3 cylinder grooves. 2. Check the reverse sun gear splines, grooves and thrust face for condition. Coat the ‘O’ ring with automatic transmission fluid and fit it to the groove 1.
