Specifications
Wheels
and Hubs
Because they are often
exposed to water, trailer
wheels and tires require
more attention than the
wheels on your family car.
The three major items to
check are lug nuts, lubri-
cation and tire pressure.
wheels and hubs
Maintain the proper torque on the lug nuts attached to the wheel
bolts. Failure to do so may result in serious injury or property
damage. Your MasterCraft dealer can provide you with the proper
torque specications (measured in foot-pounds).
Keep the wheel bearings lubricated. Failure to do so may cause
wheel failure and possible wheel loss, which may result in serious
injury or death and/or property damage.
As part of the regular maintenance, keep the axle assembly properly
lubricated. This procedure is best performed by your MasterCraft dealer.
The ll plug in the hub nose must be removed so that 80- to 90-weight mo-
tor oil can be added. “Never-seize compound” should be applied to the ll
plug, which is then re-installed and torqued to 7-ft-lbs. If at any time the oil
in the hub appears milky, the system must be serviced immediately.
Lug Nuts or Wheel Bolts
Loose wheel mounting nuts (lug nuts) can cause more than just an an-
noying wheel wobble–you could lose a wheel. Before each trip check
for loose or missing lug nuts/wheel bolts.
When tightening the lug nuts, use the correct sized-wrench. The wrong
size can round off the lug nuts and render them useless. If you lose a lug
nut, replace it promptly. The correct size varies with different models, so
you should verify the proper size with your MasterCraft dealer.
