REPLACING THE TINES
All tines should be replaced at the same time because they will wear
evenly through normal use. Work on one side at a time.
Preparing the Unit for Tine Removal
1. Stop the engine and allow it to cool. Grasp the spark plug wire
firmly and pull the cap from the spark plug.
2. Set the unit on a flat, level surface. Tip the unit back so that the
handlebar touches the ground and the engine is in a horizontal
position (Fig. 13).
NOTE: It may be necessary to wash dirt off the tines and tine shafts
before removing the tines.
Removing the Old Tines
1. Remove the cotter pin from the clevis pin (Fig. 11). Remove the
clevis pin from the double tine and tine shaft.
2. Slide the tines off of the tine shaft.
3. Repeat this process for the other side.
Installing the New Tines
1. Clean and oil the tine shaft.
2. Slide the new tines onto the tine shaft. The hubs must face
toward each other (Fig. 12). Install the single tine first. Then
install the double tine. Align the hole on the double tine with the
hole on the tine shaft (Fig. 12).
3. Insert a clevis pin through the aligned holes (Fig. 11). Insert a
cotter pin into the clevis pin.
4. Repeat this process for the other side.
5. Reconnect the spark plug wire.
WARNING:
To prevent serious personal injury, always
wear heavy gloves when handling the tines.
