2023 OWNER’S MANUAL /

Trailers equipped with the UFP actuator will also be equipped with
a Trailer Buddy Axle utilizing the VAULT bearing protector with
specially formulated Hybrid Oil™ lubricant. The VAULT combines
the benefits of oil and grease, lubricating and protecting the wheel
bearings in a sealed pressurized chamber impenetrable by
outside elements.
The system has a number of unique features not found on
conventional trailer axles. Every possible leak point on the front
and rear of the hub is sealed. The slight (3-6 psi) pressure within
the VAULT system generated inside the hub chamber will not
damage the inner oil seals. The pressure inside the hub is needed
to keep water out of the hub chamber when the hub is submerged
underwater during launch and retrieval.
Inspection or replenishment of the lubricant is not required as
part of the routine maintenance. At ambient temperatures the
oil is thick, with a viscosity approaching grease. As the bearing
temperature rises during towing, the oil thins out, replenishing
the bearings with lubricant and dissipating heat. For optimal
performance, only UFP’s Hybrid Oil Lubricant should be used in
this system.
Adding or changing the lubricant in the VAULT system is neither
necessary nor recommended during the first five years
of service. After that time, the maintenance requirements should
be undertaken only by an authorized MasterCraft dealer and only
the lubricant specified above should be used.
Wheels
Trailer wheels and tires require more attention than the wheels on a
family vehicle because they are regularly exposed to water. 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 MasterCraft dealer can provide the
proper torque specifications (measured in foot-pounds).
Keep the wheel bearings lubricated. Inspect the wheel bearings
for proper lubrication 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.
