Removing
1. Remove the air cleaner cover (see Section Removing and installing the air cleaner assembly).
2. Disconnect the remaining vacuum tube from the vacuum switch (leading to the vacuum capsule of the switch valve housing). Try the route of laying the tube.
3. Using a small flat-bladed screwdriver, pry off the base plate from the underside of the vacuum switch. The plate may be quite tight, so be very careful not to damage the nipples.
4. Remove the vacuum switch from the air cleaner housing. Remove the pad.
Installation
Installation is in the reverse order. A gasket that is damaged during assembly must be replaced. Check the tightness of the base plate on the nipples.
