Drive and Tillage Rotors
IMPORTANT
Always replace worn, broken or bent Rotor Blades.
After an initial run of 5-10 hours, check the Drive and
Tillage Rotor Assemblies to ensure that on each end of
Rotor Axle the 12-Point Flange Bolts are tight at a full
torque of 90 Ft-Lbs. If not, tighten the 12-Point Flange
Bolts diagonally to 45 Ft-Lbs then tighten to a full torque
of 90 Ft-Lbs. Repeat 90 Ft-Lbs for another 3 to 4 more
times (less than 10 percent of wrench movement).
Thereafter check Drive and Tillage Rotors every 50-100
hours or annually.
Always clean undesired foreign material that may have
wrapped around the Rotors.
Check Rotors for worn, broken or bent Rotor Blades and
replace per "
Rotor Blade Replacement Procedure on
Page 4-8." When replacing Rotor Blades, the distance on
both ends from the Blade to the Rotor Axle Shaft Step
should be equal.
See Figures 4-8 and 4-9.
