rotor before reseating blades. The blades must not have any material
underneath them when tightened. If they are not flat and tight they
will become loose very quickly.

in the diagram. Use only genuine Timberwolf nuts and washers, as
they are of a higher grade than normally stocked at fastener factories.
Failure to use the appropriate grade nuts or washers may result in
damage, injury or death. The use of genuine Timberwolf blades and
bolts is recommended.

threads and back face of the nuts. Do not apply copper grease onto
the counter bore faces of the blades or bolts.

torque setting of 125lb ft (170Nm).
