Section 13: WHEELS, HUBS & TIRES
PA1562
5
CAUTION
The actual length of thread engagement
present in an assembled wheel can not
always be determined by visual inspection of
measurement of a tightened assembly. The
relationship of the wheel cap nut seat to the
end of the stud may vary. If there is any doubt
that enough thread engagement is present,
the number of engaged threads may be
counted. Tighten all nuts in the regular
manner, then loosen one to hand-tightness.
The number of turns to disengage a 1-1/8-inch
nut should be at least five full turns. At least
seven full turns should be required to
disengage a ¾-inch nut or a M22 nut. Ideally,
when torqued to the proper load, the stud
should be flush with the face of the nut. The
face of the nut may be recessed in nuts that
are taller for improved wrenching. With most
of the nuts in present use, a few unengaged
threads at the outer end will cause no problem
provided at least 5-7 full turns are required to
disengage the nut depending on thread size.
4. ALUMINUM WHEEL ANTI-CORROSION
PROTECTION
Clean wheels often by means of a high pressure
water jet. Cleaning may be accelerated with mild
soap. Do not use concentrated alkaline cleaning
products.
When tire is removed, clean and inspect wheel
thoroughly. Remove dirt and corrosion on rim by
means of a wire brush. Do not use a wire brush
on the outer surface of the wheel.
The following measures should be taken to
maintain original appearance of the aluminum
wheels:
1. Remove any tar from wheel surface with a
good quality tar remover.
2. Spray Alcoa Cleaner (Prévost #683529)
evenly on cool outer surface of wheel. Let
work 15-20 minutes (keep wet by spraying
more Cleaner if necessary).
3. Rinse thoroughly with clean water and let air
dry. Heavy oxidation may require a repeat
application of cleaner.
4. Apply Alcoa Polish (Prévost #683528)
sparingly to a small area using a clean, soft
cloth. Work polish into surface as you would
a rubbing compound.
5. Buff, turning cloth frequently, until surface is
clean and shiny. Let air dry. Use power
buffer to improve ease of use and gloss
uniformity.
6. On completely dry, clean and polished
surface, generously apply Alcoa sealant
(Prévost #683527). Rinse thoroughly with
water while surface is still wet in appearance
(have water source ready as the dry time is
very short, usually less than 2 minutes).
7. For best results, finish by wiping the surface
with a clean rag to remove excess water,
then allow surface to dry.
Clean aluminum wheels as required to maintain
original look.
WARNING
Wheel surfaces may have sharp or cutting
edges that may cause injury to the hands. To
prevent contact with sharp edges, it is
strongly recommended to wear rubber gloves
when washing or polishing wheels.
5. WHEEL STRAIGHTNESS TEST
1. Slightly raise axle to be checked and place a
safety support underneath;
2. Check wheel lateral run-out. Install a dial
gauge as shown in figure 3, then rotate the
wheel by hand one full turn. As the wheel
turns, note any variation on the dial gauge;
CAUTION
Damage to the dial gauge could occur if it
strikes a wheel balancing weight.
3. If the variation in lateral run-out exceeds
0.0625 inch (1,6 mm), the wheel must be
replaced.
