C3 Clutch and Reverse Sun Gear Assembly
To assemble the C3 clutch and reverse sun gear assembly
(refer to figure 8.28), proceed as follows.
1. Check the orifices in the cylinder are clear of obstructions.
2. Check the C3 cylinder bush outside diameter and the
centre support inside diameter are in good condition and
not damaged. Coat the sealing rings with automatic
transmission fluid and fit into the C3 cylinder grooves.
3. 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 of the reverse
sun gear.
4. Install the reverse sun gear in the C3 cylinder, ensuring
that the 'O' ring compression is adequate but not
excessive.
Notice
'O' rings must not be twisted in the grooves.
5. Coat the C3 piston 'O' rings with automatic transmission
fluid and fat the small 'O' ring onto the inner ring and the
large 'O' ring onto the outer ring of the C3 piston.
6. Check that the bleed orifices of the piston are clean and
clear of obstructions.
7. Install the C3 piston in the cylinder until the outside
diameter of the piston enters the inside diameter of the
cylinder.
Notice
Take care not to cut the 'O' ring.
8. Assemble the spring and spring retainer on the piston.
Using tool No. 0555-331899 compress the spring
sufficiently to enable the installation of the retaining circlip,
ensuring that the circlip is firmly seated in the groove, and
remove the tool.
9. Fit the C3 wave plate to the C3 piston face, ensuring that
one crest of the wave plate of the C3 piston face is aligned
over one of the piston orifices.
10. Assemble the clutch plates and discs into the cylinder in
the following sequence :
Steel plate
