3.2.3 Changing gearbox lubricant
The gearbox oil should be changed after the first 150 hours of operation of
a new gearbox and at least once a month of normal running. A large
accumulation of metallic particles on the magnetic plugs indicates the
gearbox oil needs changing. Changing gearbox oil involves flushing of
the gearbox with diesel oil or kerosene. The gear box should be filled
with diesel or kerosene and rotated a number of revolutions by hand with
all plugs screwed in. This flushing should be repeated two to three times
or until clean. The gearbox should be filled with one of the gear oils listed
below. Gearbox capacity is approximately one-half (1/2) gallon or two (2)
liters. Continued accumulation of metallic wear particles in the magnetic
plugs indicates abnormal gear wear.
