Tie Down Vortex Hubs for Spindles - Manual (Page 4)

Removing/Remounting The Vortex Hub
Removing the Vortex Hub for inspection or maintenance should be done in a
safe location away from moving vehicles.
1. Elevate the trailer on level ground using the manufacturer’s instructions. Always
use jack stands or other solid supports. Do not rely on a jack to support the
trailer. Block wheels to keep the trailer from rolling.
2. Remove the tire/wheel assembly.
3. Place a newspaper or cloth on the ground under the hub to keep any parts from
falling onto a dirty surface.
4. Remove the Vortex grease cap by unscrewing in a counter clockwise rotation.
5. Remove the cotter pin, castle nut (in a counterclockwise rotation) and washer.
6. Remove the hub from the spindle. If you have disc brakes, you will need to
remove the brake caliper to remove the rotor. Follow separate instructions for
disc brake rotor removal.
7. Be careful not to allow the bearings to fall out of the hub.
8. Clean bearing and cup surfaces.
9. To re-install, coat bearings with Lucas Oil Marine Grease before re-installing.
10. Install bearings and place hub on spindle in reverse order as listed above.
Rotate the hub while applying approximately 50 ft. lbs. of torque to the
spindle nut. This translates into a full hand pressure load with a 12” long
wrench. This “seats” the bearings.
11. Loosen the spindle nut to remove the torque applied. DO NOT ROTATE THE HUB.
12. Tighten the spindle nut until snug, backing off only enough to line up the
cotter pin with the hole in the spindle.
13. Bend the cotter pin into place.
14.
LOAD HUB WITH LUCAS OIL MARINE GREASE USING THE INSTRUCTIONS
FOR ADDING OR CHANGING GREASE.
15. Replace the Vortex grease cap. Turn in a clockwise rotation until the o-ring on
the cap comes in contact with the hub surface. Turn an additional 1/4 turn to
seal the Vortex cap to the hub. (This is similar to installing an oil filter
in an automobile).
16. Replace tire/wheel, torque lug nuts according to wheel manufacturer’s instructions.
17. Test hub for proper end play by grabbing the tire and pulling the tire from side
to side. Readjust if necessary.
VERY IMPORTANT: RE-CHECK LUG NUTS AFTER 25 MILES OF USE.
