Replacing the valve body seal

2. Remove the engine air filter.

3. Disconnect the valve body connector.

Attention.

• Be careful not to touch the connector terminals with your hands, as this may damage the terminals.
• Water or foreign objects entering the connector may cause poor connection and corrosion. When disconnecting the connector, be careful not to allow water or foreign objects to enter.

4. Remove the hose clamp.



5. Cut off the seal with a knife as shown in the figure.

Attention.

• Be careful not to damage the gearbox housing and the valve body connector.
• To prevent foreign materials from getting inside the gearbox, thoroughly clean the seal installation area and cut off the seal without leaving any fragments.

6. Using a flat-head screwdriver wrapped in electrical tape, remove the oil seal from the gearbox housing.

Note: Remove the seal by tapping the tip of a tape-wrapped flat-head screwdriver along the inside circumference of surface A of the seal.
