end while pressing on the front side of the engine unit.
Be careful not to let the harnesses get sandwiched between the engine unit and the lower cover.
•
After installing the engine unit, route the harnesses to the harness cable guide on the left and right
side of the lower cover as shown in
Section 7-10, 11, 12 .

When the engine unit is replaced, make adjustments specified in Chapter 4, Section 6 .
