CT90/ST90 Auto Clutch
1. Remove the clutch cover. Most of the time the screws are hard to loosen. Use an impact screwdriver to avoid stripping the screw heads. If the screw heads are stripped, use a drill and drill the middle of the screw head, just enough to remove the screw head.
2. place the engine flat on the side before removing the clutch cover. Take note of the parts placement after removing the cover.
3. Remove the clutch components. The screws on the clutch filter cap are always hard, if not impossible to remove, even with an impact driver. The stripped screw can be removed by using a drill bit to drill through the screw head. Be careful, not to drill into the filter cover.
