78 • SECTION 2 --- DRIVING & SAFETY NEPTUNE 2004
Road oil and dirt build-up will cause deterioration of the rubber. Clean tires
using proper care and methods to obtain maximum service years out of the tires.
Use a soft brush and mild detergent to clean the tires. If a dressing product is used
to “protect” the tires from aging, use extra care and caution. Tire dressings that
contain petroleum products or alcohol may cause deterioration or cracking.
In many cases it is not the dressing that causes a problem, but the chemical
reaction that subsequently occurs. When these same dressing products are used on
a passenger car tire that is replaced every three to four years, it is rare to see a
major problem. However, in most cases, motorhome tires may last longer due to
limited annual mileage, and exposure.
Hub Piloted Mounting:
• Before using flange nuts that have already been used in service, apply
two drops of oil at one point between the flange and hex. This will
allow parts to rotate freely and provide the proper clamping force when
tightened. Use any common lubricant typically used for fasteners.
Examples are motor oil and general purpose lubricating oils. Excessive
lubricant is not desirable, this will not improve the nut torquing
performance. Excessive lubricant makes the nuts hard to handle,
attracts dirt to the nuts and may cause unsightly appearance to the
wheel. Only used nuts need to be lubricated.
• Since flange nuts generate higher clamping force always use grade eight
studs with hub mount wheels.
• Before installing the wheels, lubricate the hub pilot pads with a drop of
oil to prevent galling. Do not lubricate any other wheel or hub surface.
• For a hub with intermittent pilot pads, position a pad at the twelve
o’clock position to center the wheel and reduce runout.
NOTE: Loosen and tighten lug nuts in a star pattern sequence.
Sequence tighten to 50 ft. lbs. first, then sequence tighten to
450 ft. lbs. Over-tightening can cause distortion.
WARNING: Never use wheels or lug nuts different than the
original equipment as this could damage the wheel or the
mounting system. Damage to the wheel or mounting system could
cause a wheel to come off while the recreational vehicle is in
motion.
