The nylon straps
should be placed on the parts of the axle that are over

bolts and nuts into the frame to secure the bearings
and re torque the bolts to 63 lb-ft (note 2 bolts ea
side). Ensure bearings do not clamp axle assembly
together. There should be no side load on bearings.
Remove either one (B) or (L) if required. After
tightening, ensure blades spin freely by hand.
