When replacing the beater paddles, the sharp edges of
the teeth must lead in the direction of beater travel. On the
right half of the beater the teeth must point to the right side
of the spreader. On the left half of the beater the teeth
must point to the left side of the spreader. Always use H&S
special grade 5 bolts, washers, and nuts when replacing
the tips, and torque to 60 foot lbs.
WHEEL BEARING LUBRICATION, CLEAN
& RE-PACK INSTRUCTIONS
Wheel hubs are equipped with a grease zerk for regular
maintenance. Annually disassemble and clean parts in
solvent. Pack the bearings with grease and reassemble
the bearings, tighten the castellated nut on the spindle to
the point where there is no end-play and a slight drag on
the bearings. Replace the cotter key with a new one of the
correct size, bend cotter pin over and re-install cap.
