Gearcase Lubrication
When adding or changing gearcase lubricant, visually check for the
presence of water in the lubricant. If water is present, it may have settled
to the bottom and will drain out prior to the lubricant, or it may be mixed
with the lubricant, giving it a milky colored appearance. If water is noticed,
have the gearcase checked by your dealer. Water in the lubricant may
result in premature bearing failure or, in freezing temperatures, will turn to
ice and damage the gearcase.
Examine the drained gearcase lubricant for metal particles. A small amount
of metal particles indicates normal gear wear. An excessive amount of
metal filings or larger particles (chips) may indicate abnormal gear wear
and should be checked by an authorized dealer.
DRAINING GEARCASE
