27.1a Tools needed to replace spark plugs
1. Spark plug replacement socket; 2. Torque wrench; 3. Ratchet wrench; 4. Extension cord; 5. Wire sensor
27.1b Use a wire gauge to check the spark gap
27.1v To measure the gap size, carefully bend the outer electrode
1. To replace the spark plugs, you will need a special socket with a rubber bushing that will hold the spark plug during installation, a ratchet wrench and a wire gauge to measure the spark gap. When replacing the spark plugs, adjust the spark gaps of the new plugs and replace the plugs one by one (27.1a, 27.1b and 27.1c).
Removal
27.2 When disconnecting high voltage wires, grasp the cap, not the wires
2. Grasp the wire connection cap, turn it and remove it from the spark plug (27.2).
3. Clean the area around the spark plug with compressed air.
27.4 Using a socket wrench with a special socket and an extension, unscrew the spark plug
4. Remove the spark plug (27.4).
5. Inspect the spark plug and compare it with the spark plugs in the photographs.
Installation
27.6 When installing spark plugs, use a 5 mm diameter tube to avoid damaging the threads
6. To make it easier to install the spark plug, place a piece of 5 mm diameter tube on it, which will serve as a universal joint when screwing in the spark plug (27.6).
7. Connect the wire to the spark plug.
8. Replace the remaining spark plugs in the same manner.
