Removal
Before starting work, ensure the motorcycle is stabilised
and adequately supported. This will help prevent it from
falling and causing injury to the operator or damage to
the motorcycle.
1.
Remove the seat (see page
17-17
for Rocket 11 I and
Classic, see page
17-18
for Rocket III Touring).
2.
Disconnect the battery, negative (black) lead first.
3.
Drain the coolant (see page 12-6>.
Do not remove the coolant pressure cap when the
engine is hot. When the engine is hot, the coolant inside
the radiator is hot and also under pressure. Contact with
hot coolant will cause scalds and skin damage.
4.
Turn the steering to left or right full lock.
5.
Disconnect the coolant hoses from the water pump.
