Tighten Spanner Nuts
1. Tighten the spanner nut until a rolling
resistance is felt.
2. Roll the spindle housing back and forth
to seat cones into cups while
continuing to tighten spanner nut.
3. To insure proper bearing shaft seating,
the spanner nut must be torqued to
create a preload on the bearings. To
create the preload:
a. Temporarily install a ¾” x 3” long
bolt into the blade holder bar five
inches from the center point as
shown in the top drawing on the
following page. Tighten to 100 ft
lbs.
b. While holding the spanner nut with
the provided wrench, use a torque
wrench to tighten the previously
installed bolt to 10 ft lbs.
c. Turn the spindle back and forth to
help seat cones. Re-torque and
turn the spindle again.
d. Repeat Step c, re-torquing until the
bolt torque stays constant at 10 ft
lbs.
4. Adjust the spanner nut to nearest outer
tab and using a punch and hammer,
bend the tab to lock the spanner nut to
spindle.
5. Install second spanner nut washer.
6. Install the second spanner nut as a
jam nut and tighten with the provided
wrench.
7. Using a punch and hammer, bend the
tab up on the washer into the slot to
lock second spanner nut.
8. Remove the ¾” x 3” long bolt installed
in Step 3a.
