CLEANING, INSPECTION, AND REPAIR
A torn track cannot be vulcanized, it must be replaced.
Liquid neoprene can be applied to a frayed track to help restore its
original appearance.
Bearings are sealed, therefore require no greasing. Turn bearings
in hand. Sealed bearings do not turn freely, but
if
they are rough, they
must be replaced.
Axles - check for straightness by rOlling one flat surface. Replace if
bent.
Splines - inspect for excessive wear.
Sprockets - check for excessive wear, or Nylon pe'eling or worn off.
