Transmission
The lubricant in the transmission and free
wheeling units should be maintained to the level
of the filler plugs "A" and "B."
The plugs "C" and "D" should be removed
every 5000 miles and the lubricant drained out.
Replace the plugs and fill through plug "B" with
one quart of kerosene. Run engine with transmis-
sion in neutral and clutch engaged for one min-
ute. Drain kerosene, replace drain plugs and fill
through "B" with three pints of S. A. E. No. 90
gear oil (in winter use S. A. E. No. 80), allowing
the oil to drain into the main transmission housing. If the full three pints cannot be
put in at "B," add the balance at "A."
It is essential that good oil of the proper body be used to insure proper protection
against wear and permit proper gear changing. Buying according to the S. A. E.
specifications (this is shown on most oil containers) will insure you of obtaining a
satisfactory lubricant.
Universal Joints
Use Fiber Grease
Remove the plug "A," shown in the illustra-
tion, of the rear universal joint and inject good
fiber grease until grease appears at vent hole in
shaft opposite filler hole. There is a plug simi-
larly located just back of the front universal joint
for filling.
The use of a proper grease at these points is
very important in order to insure lubrication.
These units should be filled every 2000 miles.
The universal joints are often neglected until wear has occurred to such an extent
that replacement is necessary. Wear at these points throws the propeller shaft out
of balance, causing vibration, and thus offsets the care taken in manufacture to
obtain accurate balance which is necessary for smooth operation at high speeds.
