Generator Oil Cups; 12
Two oil cups on the generator conduct lubricant to the forward and rear
bearings on the armature shaft. A few drops of engine oil should be applied
to each cup every 1000 miles.
Timer-Distributor Oil Cup; 5
The oil cup at "5" is for lubricating the ball bearing at the upper end of
the timer-distributor shaft. A few drops of engine oil should be applied
every 1000 miles.
Fan; 7
The fan is lubricated by oil contained in a reservoir in the fan hub. The
screw plug in the outside of the reservoir should be removed every 1000
miles and engine oil should be added to bring the oil to the proper level. In
adding oil, it is necessary to add somewhat more than enough and then
drain off the surplus by turning the fan so that the hole points down. A
short stand-pipe inside the reservoir insures that the proper amount of oil is
retained. The filling hole should be pointed down for at least half a minute
to allow air to enter and permit the surplus oil to flow out. A cloth or
piece of waste may be held under the hole to catch the oil. Do not put grease
or heavy oil in the fan.
Water Pump; 8
A grease cup is provided for lubricating the water pump. This cup should
be turned down and refilled with cup grease every 1000 miles.
Figure 1$. Oil for lubricating the fan is carried in the fan hub. The supply must be
replenished everv 1000 miles. Grease or heavy oil must never^be used in the fan.
Grease Gun Connections; G
CHAPTER III
General Lubrication
SPRING bolts, steering connections, brake rocker shafts and other points are
provided with connections to fit the grease gun supplied with the tool
equipment. These points are indicated by "G" in Fig. 29. Chassis lubricant
should be applied to these points with the grease gun every 1000 miles.
Clutch Thrust Bearing; 14
The lubricating point on the clutch thrust bearing is fitted with a grease
cup on an extension that passes through the right-hand side of the transmission
case. It can be reached after lifting the right side of the hood.
The grease cup should be filled with fiber grease and turned down two or
three times every 2000 miles.
Transmission; 15
The transmission case should contain sufficient lubricant to bring the
level up to the filling hole at the right-hand side. The level should be
inspected every 2000 miles and chassis lubricant added if necessary.
If, in cold weather, the transmission gears are difficult to shift, the lubricant
should be thinned by the addition of kerosene. On the return of warm
weather in the spring, the drain plug should be removed from the bottom of
the transmission case and the lubricant should be drained and replaced with
fresh lubricant. Two and one-half quarts of lubricant are required to fill
the transmission case to the proper level.
Rear Axle; 18
The rear axle housing should contain enough lubricant to bring the level
up to the filling hole in the rear cover plate. The level should be inspected
every 2000 miles and chassis lubricant added if necessary.
In weather cold enough to warrant thinning the transmission lubricant,
the lubricant in the rear axle should also be thinned. On the return of warm
weather in the spring the drain plug should be removed from the bottom of
the axle housing and the lubricant should be drained and replaced with fresh
lubricant. Two and one-half quarts of lubricant are necessary to fill the rear
axle housing to the proper level.
