Installing the drum extensions
1. Remove the narrow scraper(1) from the front drum. Place the scraper

available. You will reuse the screws and washers to install the wide
scraper at the end of this procedure.
2. Remove three M16x25 screws(4) from each end of the front drum as
shown.

mounting holes as shown in viewA below.
Note: As you align the mounting holes, make sure the “sheep’s foot”
lugs on the drum and drum extension are offset from one another.
4. Fasten the drum extension with three M16x80 screws(6) in the loca-
tions shown in viewsA and B below. Torque to 167Nm (123ft.lbs.).
