   Note: Using a friction disc with less than 7.65 mm (0.300 inch) of friction material will result in accelerated wear. Do not use the color of the friction disc as an indication of wear. The overall thickness and disc groove depth are better indications of wear.

3. Inspect friction disc (6) for wear. Replace the friction disc if the thickness of the friction material is less than 7.65 mm (0.300 inch). Immerse the friction disc in clean SAE 30 oil. Install friction disc (6), sun gear (5) and three springs (4).
