11. Thoroughly clean the mating surfaces of the blade and the rotor. Any material left
between the blade and rotor will cause the blade to become loose very quickly.
12. Ensure that the mounting bolts and nuts are suitable for re-use. (Refer to Section 6.7
"
Check and Replace Fasteners" on page 40.) If any doubt exists, use new items.
13. Apply a smear of anti-seize compound (copper ease) to the bolt threads and back face
of the nuts. DO NOT apply copper ease to the counter-bore faces of the blades or
bolts.
14. Fit the blade to the rotor using the retaining bolts, washers and Nyloc nuts. The use of
genuine Timberwolf blades and bolts is recommended (Figure 21).
15. Tighten the blade bolts to the correct torque
setting. (Refer to Section 6.7 " Check and
Replace Fasteners" on page 40.)
