(3) Grease application
Place pressure gun securely on the fitting, so that there is no leakage between
fitting and applicator. A pp y pressure until
old grease is forced out and new
I
grease appears. Th is will insure that the grease cavity has been filled with
clean grease and that old, contaminated grease has been forced out.
CAUTION: DO NOT FORCE GREASE OUT OF DRIVE SHAFT UNIVERSAL
JOINTS. APPLY ONLY ONE OR TWO STROKES OF A
HAND GUN, OR ONE OR TWO CYCLES OF PNEUMATIC
PRESSURE EQUIPMENT. GREASE SEALS MAY BE FORCED
OUT IF TOO MUCH GREASE IS APPLIED.
Use an oil can to lubricate points such as linkage, etc., which are not
equipped with grease fittings. A very light grease such as "Lubriplate" may
also be used if it is preferred to lubricating oil.
G. Transmission, Rear Axle, and Steering Gear Lubrication (See Fig. 9)
(1) General
A common, multi-purpose gear lubricant is used in each of the above units.
Since mobileoperation of the self-propelled unit is very limited, it is unlikely
that the lubricant will require changing except after repair or overhaul. How-
ever, it is important to check the lubricant level regularly in accordance with
Lubrication Chart, Figure 1.
N OTE : Be sure the vehicle is LEVE L when the following checks are made.
' (2) Transmission
(a) Remove the topmost pipe plug on the right side of the transmission (see
Fig. 9). This is the filler plug. Lubricant should be level with the
bottom of the filler hole, or slightly above this level, causing a very
small flow from the filler hole when the plug is removed. If lubricant
is below proper level, add lubricant in accordance with Lubrication Chart,
Fig. 1, until lubricant flows slightly from filler hole.
(b) If the transmission is equipped with a magnetic drain plug, remove and
clean the drain plug annually. The plug has 3/4 in.-14 pipe threads.
Install a standard pipe plug of this size in the drain hole while cleaning
the magnetic plug.
