service. After that time, the maintenance
requirements should be undertaken only
by an authorized MasterCraft dealer and
only the lubricant specied above should
be used.
Tie Down Engineering-equipped trailers:
Trailers equipped with Tie Down Engi-
neering actuators are also equipped with
Vortex hubs and spindles. The hubs are
pre-greased and assembled at the factory.
As a result, they should not require any
additional adjustments. The Vortex hub
uses tapered roller bearings adjusted to a
maximum .006 end play. The twelve-sided
castle nut easily maintains this maximum
.006 end play. The conguration requires a
minimal amount of end play that is factored
in at the time of assembly.
The rear seal rides on a stainless steel
wear sleeve. This provides longer life for
the seal as the surface does not corrode.
Corroded or rusted seal surfaces act like
sandpaper on the seal, causing premature
seal failure, which is why every reasonable
attempt has been made to avoid that.
Vortex lubrication makes changing or
adding grease easy because the hub does
not need to be removed. The threaded
grease cap is easy to remove and replace.
No more knocking the cap off with a ham-
mer. Vortex requires Lucas Oil Marine
grease, a premium lithium-based complex
fortied with rust and oxidation inhibitors,
and high-pressure additives that provides
a high degree of moisture resistance and
wash-out properties.
Use only Lucas Oil Marine Grease when
adding or replacing grease in the Vortex
hub. Using any other grease will void the
warranty.
The Vortex hub/spindle is designed to be
a no-maintenance hub for six (6) years. If
you need to add grease or remove the hubs
for any reason, follow these instructions:
1. Remove the Vortex grease cap, unscrew-
ing in a counterclockwise rotation.
2. Use a standard grease gun loaded with
Lucas Oil Marine Grease to pump the
grease into the zerk tting located on the
end of the spindle.
3. Pump the grease into the zerk tting
while slowly rotating the wheel. Grease
will ow 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
