3. Pump the Lucas Oil Marine grease into
the zerc fitting while slowly rotating the
wheel. Grease will flow out of the hub
around the front bearing.
4. When the grease appears to be the new
clean grease, remove the grease gun.
5. Replace the Vortex grease cap. Turn
in a clock-wise rotation until the o-ring
on the cap is 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)
REMOVING/REMOUNTING FOR 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
manufacturers 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 un-screwing
in a counter clockwise rotation.
5. Remove the cotter pin, castle nut (in a counter
clockwise 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. Lossen 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
clock-wise rotation until the o-ring on the
cap 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 manufacturers instructions.
17. Test hub for proper end play by grabbing
the tire and pulling the tire from side to side.
Readjust if necessary.
18.
VERY IMPORTANT: RE-CHECK LUG
NUTS AFTER 25 MILES OF USE.
