clockwise rotation until the o-ring on the
cap is in contact with the hub surface. Turn
an additional one-quarter (1/4) turn to seal
the Vortex cap to the hub. (Similar to in-
stalling an oil lter in an automobile.)
If the bearings need to be adjusted or
replaced, the work should be done only
by an authorized MasterCraft dealer.
Failure to contact MasterCraft for pre-
approval during the warranty period
will void the warranty.
The wheel bearings have been precisely
torque-set at the factory. To assure the bear-
ings are in good working order, check the
bearing adjustment at least once a year by
following this procedure: Jack up one side
of the trailer. (Be certain to use jack stands
and check the trailer wheels to keep the
trailer from moving during the inspection.)
Grip the edge of the tire and see if it can be
rocked or moved. If the outer edge of the
tire moves at all, the bearings may need
to be readjusted.
A slight amount of oil seepage at the rear
seal is normal and necessary to lubricate
the wiper lip of the seal for long life and
sealing contaminants out. If excessive leak-
age is occurring, however, contact an au-
thorized MasterCraft Dealer for assistance.
Wheels
Because they are often exposed to water,
trailer wheels and tires require more atten-
tion than the wheels on a family vehicle.
The three major items to check are lug nuts,
lubrication and tire pressure.
Maintain the proper torque on the lug nuts
attached to the wheel bolts. Failure to do so
may result in serious injury or death and/
or property damage. An authorized Master-
Craf dealer can provide the proper torque
specifications (measured in foot-pounds).
Keep the wheel bearings lubricated. In-
spect the wheel bearings for proper lubri-
cation before each use. Failure to do so
may cause wheel failure and possible wheel
loss, which may result in serious injury or
death and/or property damage.
Aluminum wheels also require attention
to routine maintenance, particularly in keep-
ing them clean. Failure to do so may result
in damage that is not covered by warranty.
The trailer and wheels should be washed
weekly during boating season, and after ev-
ery use if the trailer has been submerged
in salt or brackish water. Use a soft brush,
mild detergent and/or mild degreaser. A
quality spray-on wheel cleaner may also
be used. Ensure that any product used is
specically indicated for use on aluminum.
(Many cleaners are too harsh and will re-
sult in pitting or other damage to the wheel
surface.) Many car washes use strong
