would indicate water intrusion
and the lubricant should be re-
placed. Also check the seals for
damage. When on a trip, make
it a habit to check the wheel
hubs every time you stop for
gas or refreshments. If the hub
feels abnormally hot, the bear-
ings and brake should be in-
spected before continuing the
trip.
e oil level in the bear-
ing cavity of the rotor should
always be maintained at the
top of the logo on the face of
the cap (halfway up the sight
glass). A regular check of the
torque on the cap should also
be performed. e proper torque should be 25-30 ft.-lbs. If sudden oil loss is
incurred, the torque on the cap should be immediately checked and a visual in-
spection of the rear seal should be performed to check for signs of leaks. As
always, anytime the hub is disassembled for any maintenance, the bearings and
seal should be inspected for signs of wear.
Wheel Bearings and Braking System
Wheel bearings and the braking system on the trailer should be inspected
annually. If the bearings or bearing race show signs of scoring, they should be
replaced, as well as any worn brake parts. An authorized MasterCraft dealer
should perform this inspection and repair (as necessary).
Tires
e most common cause of trailer tire trouble is under-inflation. It is impor-
tant, therefore, to always maintain correct air pressure as indicated by the tire
manufacturer on the tire’s sidewalls. Always check the air pressure when the
tires are cold. Tires heat up and the air pressure increases after traveling short
distances.
