Remove upper side cowl

First, remove the upper side cowl, where the turn signals are installed.

(For details, please refer to the maintenance record “How to remove side cowls and panels etc.” STEP 1-14.)

Remove wiring

＜Remove wiring＞

Remove the wiring from the clip fixed to the upper side cowl.
Lift up the clip while pressing down on it to remove it.

STEP

Remove turn signal 1

＜Remove turn signal 1＞

Hang the wrench (10 mm) on the nut to hold it in place and use the hexagonal wrench (5 mm) to remove the bolt.

At first, I used a hexagon socket, but it hit the turn signal body, so I used a hexagon wrench.

STEP

Remove turn signal 2

＜Remove turn signal 2＞

Move the claw part of the turn signal backward and outward to remove it.

STEP

Remove turn signal 3

＜Remove turn signal 3＞

Then, pull the turn signal outward and remove the connector.

Disconnect the left side in the same way.

STEP

Removed turn signals

＜Removed turn signals＞

For left side: Connector color… Black
For right side: Connector color … Green

Not only the color of the connectors, but also the turn signals themselves have a left and right side, and the one with the drain hole (○) is on the bottom.

STEP

Removed turn signals front and rear (Left)

＜Removed turn signals front and rear (Left)＞

For front: 29mm
For rear : 14mm

You may not notice it, but the length of the mounting part is different for the front and rear.
When replacing a turn signal on one side only, be careful not to mistake the part number.

STEP

Install turn signals

To install, simply follow the procedure in reverse order of removal.

Be careful not to mistake the left and right sides.
Before installing the upper side cowl, be careful not to forget to connect the connectors.

(For details on how to install the upper side cowl, please refer to the Maintenance Record “How to install side cowls and panels etc.” STEP 12 or later.)

3. Summary

Here is a summary of how to remove and install the front turn signals.

The process should not be difficult as all you have to do is to remove the bolt and nut (one location).
Actually, I noticed the difference between “left and right” and “front and rear” turn signals when I removed them.
