housing until the bearing cone contacts the cup in the Housing. During this step take care not to damage the
seal.
While supporting the Spindle and Housing turn the assembly over so that the assembly is setting on the spin-
dle.
Install the upper bearing (4) on the spindle shaft (1).
After the Upper Bearing is installed, install the nut (5) with the chamfer facing up. Run the nut down against the
bearing, but do not torque the nut at this time. Clamp the spindle Housing in a vise so that the spindle shaft
can rotate. Tighten the nut until the spindle shaft has a rolling torque of 25 in-lbs (that is it takes 25 in-lbs to
rotate the spindle shaft).
Install the tanged lockwasher (6) with the outside prongs facing upward.
Install the top nut (5) with the chamfer facing down. Block the spindle to keep it from rotating and torque the top
nut to a minimum of 100 ft-lbs. Bend the tang of the lockwasher to fit into one of the grooves of the top nut.
Install vent plug (8) and Grease Fitting (9).
Fill spindle assembly with NLGI EP#2 Grease (Approx 22 oz.)
