Craftsman 0220 - Manual (Page 49)

• After removing the grease cap, cotter pin, spindle nut and spindle washer,
remove the hub and drum to inspect the bearings for wear and damage.
• Replace bearings that have flat spots on rollers, broken roller cages, rust or
pitting. Always replace bearings and cups in sets. The inner and outer bearings
are to be replaced at the same time.
• Replace seals that have nicks, tears or wear.
• Lubricate the bearings with a high quality EP-2 automotive wheel bearing
grease.
Every time the wheel hub is removed and the bearings are reassembled, follow the
steps below to check the wheel bearings for free running and adjust.
• Turn the hub slowly, by hand, while tightening the spindle nut, until you can no
longer turn the hub by hand.
• Loosen the spindle nut just until you are able to turn it (the spindle nut) by
hand. Do not turn the hub while the spindle nut is loose.
• Put a new cotter pin through the spindle nut and axle.
• Check the adjustments. Both the hub and the spindle nut should be able to
move freely (the spindle nut motion will be limited by the cotter pin).
10.2.9 lug Nuts (bolts)
Lug nuts are prone to loosen right after a wheel is mounted to a hub. When driving
on a remounted wheel, check to see if the lug nuts are tight after the first 10, 25 and
50 miles of driving and before each tow thereafter.
WARNING
Lug nuts are prone to loosen after initial installation, which can
lead to death or serious injury.
Check lug nuts for tightness on a new trailer or when wheel(s)
have been remounted after the first 10, 25 and 50 miles of
driving.
WARNING
Metal creep between the wheel rim and lug nuts will cause rim to
loosen and could result in a wheel coming off, leading to death or
serious injury. Tighten lug nuts before each tow.
WARNING
Do not use the Assist Wheel to support the Trailer while
changing your tires. Trailer could tip over causing serious injury
or death.
