Trailer Wheel Bearings (figure 4.3b):
Most of the
units are equipped with "EZ-Lube" grease fittings. This
allows the operator to grease the bearings without
removing the hubs. The "EZ-Lube" feature consists
of axle spindles that have been specially drilled and
fitted with a grease zerk in their ends (fig. 4.3c). When
grease is pumped into the zerk, it is channelled to the
inner bearing and then flows back to the outer bear
-
ing and eventually back out the grease cap hole. The
trailer wheel bearings should be checked and greased
after the first 30 days of service then at the beginning of
every season.
