Bearings - Scarab SB Series Owner's Manual

If the brakes need bleeding, consult your Scarab
dealer for assistance. If unavail able, a brake or auto
repair facility can perform the repair.
Refer to the manufact urer's litera ture included in
the owner's packet for additional information on the
brake system.
J. Bearings
Wheel bearings and seals should be inspected at the
same time as brakes. Have worn or defec tive parts
replaced.
The Scarab trailer is equipped with Vortex hubs/
spindles from Tie Down Engineering and the infor-
mation which follows comes from the manufacturer's
literature. The hubs are pre-grease and assembled
at the factory and should not require any additional
adjustments. See Figure F18.
Figure F18: Vortex Hub
Should the hub/bearings require additional lubrica-
tion for any reason, the Vortex lubrication system
allows you to do so without removing the hub or
having to re-adjust the bearings. New Lucas Oil
Marine grease is pumped into the zerc fitting at the
end of the spindle, travels to the rear bearing where
the new grease pushes out the old grease through
the rear bearing, center of hub, and then through the
front bearing. See Figure F19.

(Adding Grease)
To add or change Lucas Oil Marine grease in the
Vortex hub follow these steps:
1. Remove the Vortex grease cap, unscrewing in a
counterclockwise rotation.
2. Use a standard grease gun loaded with Lucas
Oil marine grease to pump grease into the zerc
fitting located on the end of the spindle.
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 con-
tact 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)
NOTICE
To maintain the factory warranty, Lucas Oil
Marine grease must be used when adding or
replacing grease in the vortex hub.
