Removing and Installing

Special tools and workshop equipment required
♦ Puller - T10530-

Note

♦

The ignition coils are easier to remove when the engine is

warm. The grease that is used for installation helps the ignition

coils or spark plug connectors to free up more easily when the

engine is warm.

♦

Ignition coils with power output stage and spark plug connec‐

tors can be obtained individually for repairs. Refer to Parts

Catalog.

Removing:
– Remove the engine cover. Refer to

⇒ “3.1 Engine Cover, Removing and Installing”, page 38

 .

– If equipped remove the ground cable -arrows-.

– Release the connector and disconnect all the connectors at

the same time from the ignition coils.

– Remove the bolts for the ignition coil that is being removed.
– Insert the Puller - T10530- in the ignition coil opening -1-.

– Turn the knurled nut -2- clockwise until the puller is clamped.

– Carefully remove the ignition coil vertically upward using the

Puller - T10530- .

Note

♦

Ignition coils with power output stage and spark plug connec‐

tors can be obtained individually for repairs. Refer to Parts

Catalog.

♦

The spark plug connector is removed from the ignition coil by

hand.
