3. ENGINE LUBRICATION
It is extremely important that a stable, high
qual- ity enqine lubricating oil is selected for
use in the Model "W3 " Whee1 Tra ctor's engine .
It is also ex- tremely important that the
correct weight (SAE Vis- cosity Rating) of oil
is se lected, depending upon the prevailing
air temperatures .
fluid or free flowing within the specified air
temper- ature ranges . The use of either heavier
or lighter body oils than recommended may seriou
sly affect engine lubrication and performance .
Too light an oil used during warm
temperature s may result in high oil consumption
and is apt to cause increased engine wear. Using
too heavy an oi1 during cold temperatures will
affect starting, and may result in a poor rate
of lubricant distribution causing in- creased
wear .
U sing lubricating oils of the recommended SAE
Viscosity Rating as sure s you that the oil will
remain

approximately 1 00 F, before pouring it back
into the crankca se, ju st prior to starting .

• IMPORTANT Ghange the crankca se oil
  frequently when severe operating conditions
  exist. The oil will eventua lly become
  saturated with contaminan.ts and lose its
  protective properties .
• AN IM PORTANT PRECAUTION FOR DIESEL ENGINES
• Before using a new Diese1 Tractor in the field,
  drain factory installed, special preservative
  oil mom the crankcase . Refill crankcase with
  Service DS (or Series 3) oil of the correct

CHECKING CRANKCASE OIL LEYEL Gheck the engine off
level daily, before starting the day's work, by
means of the bayonet gauge rod (dlpstlck) , see
Figures 2 and 3. The dipstick has "FULL" and
"LOW" marks . Add sufficient oil through filler
opening to have oil level Just reach the "FULI"
mark. DO NOT OVERKILL.
ON DIESEL ENGINES Before using a new Diesel
Tractor in the field, drain factory-ins tailed,
speci- al preservative oi1 from the crankcase .
Refill crank- case with Service DS (or Series 3)
oil of the correct viscos ity for the prevailing
air temperature .
1 . Drain oil, while hot, after the first 20
hours of operation also change filter element.
See T-ig- ure s 2 and 3 for location of dra in
plug . After the initial oil change, change the
oil after every 1 00 hours operation .
PS?
Allow oil to drain for several minutes , replace
the plug (with gas met in place) and tighten se-
curely. If engine service is severe frequent
starting and stopping, high or low operating
tempera- ture s the crankcase should be
drained more often to prevent the formation of
sludge and harm- ful depos its in the engine .

Diese1 engines . Fill to "FULL" mark on dipstick.
Figure 2 - Checking Oil Level (Gasoline Engine)
When adding oi1, allow sufficient time for
the oil to run down before checking oil level.
N.ever attempt to check crankcase oil level
while the engine 1s running .
Always use a high-quality, stable engine oil
having the correct A.P.I. service designatiori
and the correct viscos lty.

HYDRAU UG OIL REGO MMENDATIONS
With high precis ion and complex hydraulic pumps
and systems , the choice of a superior hydraulic
oil is the they to long life and low maintenance
. In co- operation with one of the leading
refineries , the Gase Hi-Lo TGH Oil has been
developed as a scientific answer to the
protection of these finely machined components .
Figure i ñ - Power Steering Cylinder
CHECXINGOILLEVEL
Gheck the oil leve1 after every 50 hours of
opera- tion. Be sure to wipe the cover clean
before remov- ing. Keep the ci1 level one inch
from top of bowl. A replaceable filter eleme nt
is provided in the reser- voir, see ri qwe 1 7.
After 1 000 hours of operation, or more often in
extremely dusty conditions , replace this filter
with a new one .
This non- foaming oil is for all season use re-
mains stable from - 55 F to 230 F. Gentra1
Parts Division in Racine has this oil in stocii .
It is recom- mended as the best oil available
for use in the Mode1 "W3 " Tractor's torque
converter and hydraulic sys- tems .

service designation, MS- DG . Only a good grade
oi1, with non- foaming characteristics should be
used.
3. Place the Shuttle Shift lever in neutral
position and have the engine IDLING. Check the
oil level with the dipstick, see Figure 18. The
most ac- curate reading will be made if the
dipstick is held with the curved top toward the
rear, then insert ed and withdrawn very
rapidly. This will mini- mize the chance of oil
being thrown on the dip- stick by gears .
Viscos ity Recommendations (Above 0 F) ...
(Below 0 F) .
SAE 10W ... SAE 5W
If neces sary, add sufficient Gase Hi-Eo TCH Oil
to bring the level to the "FULL" mark on the
dipstick . DO NOT OVERKILL this results in a
"s luqqish " Tractor.
..
CHEAP GRADES OF OIL ARE NOT SUITABLE FOR USE IN
HYDRAU LIC SYSTEM S.
If the reservoir is low, the Torque Gonverter
Drive may act erratically. This condition is
usually worse with the Tractor going up or down a
hill due to the oil in the reservoir being beyond
the reach of the suction tube on the oil pump .
OIL VISGOS ITY
If Gase Hi-Lo TGH Oil for all season use is not
use d, be sure to follow the viscosity
recommenda- tions for the alternate oil MS- DG
service desig- nation motor oil.
4 . Replace fill plug and tighten securely.
GHECKING HYDRAU UG OIL LEVEL
DRAINING HYDRAULIC OIL
It is exteme ly important that the proper oi1
level be maintained. Too high an oil level will
cause "flooding " of the flywheel housing, los s
of power, and overheating of oi1. Too low an
oil level will result in inefficient operation
and damage to the Torque Converter Drive and,Zor
the hydraulic system .
The hydraulic oil must be drained after every
1000 hours operation or once a season, whichever
occurs first.
To drain the torque tube reservoir and converter
unit, proceed as follows
To check the oil level, proceed as follows
I . Drive the Tractor onto a level surface .
Allow the Tractor engine to run until the oil is
up to oper- ating temperature . Place the Eagle
Hitch draft arms in the lowered position
(with the control valve in the neutral position)
so that all oil is drained from the rockshaft
cylinder.
1 . Drive Tractor onto a level surface .
2 . Before checking the oi1 level, allow the
7ractor e ng ine to run until the oil is up to
operating tem- perature . Also have the Eagle
Hitch (if used) draft arms raised and any other
hydraulic cylinder (if used) with piston roa
extended.
2 . Remove two (2) l,Z2 inch pipe plugs , she
Figure 19. Allow the oil to drain for several
minutes .
3. Have an ass i stant turn the engine over s
lowly while you observe the lining up of plug "A
" with the front drain hole in the torque tube .
Then use a 3,Zl 6 inch Allen wrench to remove
plugs "A" and B" .

should be blown dry with compres sed air if
damaged the element must be replaced .
Fa ilure to keep the breather clea n may result
in a pres sure build-up in the reservoir, thus ,
forcing oi1 past the oil seals and gas lets .

The importance of changing the Torque Gonverter
Drive oil filter element cannot be overemphas i
zed . The life of the e ntire s ys tern depends a
great deal on the cleanlines s of the oil. Dirt
and foreign matter are the No . 1 enemy of the
torque Converter Drive system. If cleanlines s
precautions are not followed, trouble will soon
develop .

IMPORTANT IF THE TRACTORIS EQUIPPED BMH AN EAGLE
HITGH OR REMOTE HYDRAU LIGS ANOTHER FILTER
ELEMENT IS LOGATED ABOVE THE TORQUE iUñL
Because the Torque Converter Drive and Eagle
Hitch Remote Hydraulics systems utilize a
common reservoir in the torque tube, both
filter elements must be replaced at the same time
interval.
2 . If neces sary to loosen, tap the cap LIGHTLY.
Re- move cap and lift filter element out of the
hous- ing . the flow of oil through the element
is from the inside to the outside . Thus , most
of the dirt and foreign matter will have
collected on the in- side of the element.
SERVICING HOUSING In some instance s where the
filter has not re- ceived the proper attention,
it may be nece s sary to break the filter element
to remove it from the hous- ing. Always examine
the bottom of the hous ing for dirt or foreign
matter. If this condition exists , remove inlet
(bottom) line and outlet (top) line from the
hous- ing. Then remove mounting cap screws And
lift the housing from the Tractor.
Thoroughly clean filter housing, making abso-
lutely certain all dirt and foreign matter are
removed from the inside and es pecially the
bottom . DO NOT USE LINTY GLOTHS TO GLEAN THE
HOUSING.
HYD
After the housing has been thoroughly cleaned,
reinstall on the Tractor.

PASS THIS INFORMATION ON TO THE OPERATOR
Re- place the filter element(s) after the first
20 hours of operation and every 200 hours
thereafter on new units . Follow these same
precautions on Tractors which have had service
work performed on the Torque Gonverter or any
part of the torque tube, regardles s of the
number of hours on the unit .
INSTALLING FILTER ELEMENT
To ins ta11 replacement filter element, proceed
as follows
1 . Install new filter element, making certain
it is properly seated in the bottom of the
housing .
All of the oil in the Torque Gonverter Drive sys-
tem is circulated through the oil filter. If
dirt col- lects in the filter, it will act as a
restriction . The filter is spring loaded,
see Figure 23. When the oil is cold and too
heavy or the filter element is plugged, the
oil will bypass the element. THUS, THE OIL
WILL CIRCULATE WITHOUT FILTRATION. THIS WILL
GAUSE PREMATURE FAILURE OF THE TOR- QUE GONVERTER
SYSTEM
2. Position the cap with retainer spring,
over the filter element.
3. To prevent oil leakage, make sure the rubber
"O " ring for the cap i s in place and riot
damaged, see Figure 23.
HOUS ING
IN AN EMERGENGY, the same filter element could be
replaced, PROVIDING it was cleaned in mineral
spirits or some solvent that would evaporate .
How- ever, this is for TEMPORARY usage and a NEW
FILTER ELEMENT must be secured immediately .

Ga se Ga soline Engines are des igned to
operate on regular-grade ga soline . the
anti-knock quality of regular-grade gasoline, as
indicated by its octane numbers , will give full
power and economy together with long engine
life and low maintenance costs . Third- grade
gas oline should not be used. Knoclt or
detonation re suiting from a lack of anti-knock
qual- ity may cause premature failure s of
engine parts , such as cylinder head gas frets ,

and 90. 7 research method. Case engines are de-
signed to operate on gasoline having a minimum
re- search method rating of 90 . 7 octane .
Two octane number ratings , motor method and re-
search method, are used to define the anti-
knock quality of a gasoline . In recent years
it has be- come common practice in the
petroleum industry to refer only to the research
method rating rather than the motor method
rating. Therefore, when only one octane number
rating is given for a gas oline and the method is
not specified, it can be as sumed to be the
research rating.
The average octane number ratings for regular-
grade qas oline (October 19 5 7/ are 83 . 5 motor

This Gase Diese1 Engine is de s igned to
operate most efficientiy when us ing a NUMBER 2
DIESEL FUEL. Most well-known refiners and
distributors market a good grade Diesel fuel and
there should be no difficulty in obtaining same .

CETANE RATING
The Getane Rating is the self-iqnitin uality of
a Diesel fue1. Do not apply Cetane Rating to
Diesel engine performance as it would apply to
gasoline octane rating to sparti ignition engine
performance . High Cetane Ratings do not neces
sarily provide for improved Diesel engine
performance .
The use of Number 1 Die se1 Fue1, which is a
lighter fuel, may result in a los s of engine
power and also increase s fuel consumption,
since it has les s heat content and a lower vis
cos ity than Number 2 Diesel Fuel. The like of
the injection pump may also be affected due to
the lack of lubricant in the lighter Number l Die
se1 Fuel . PROTECT YOUR FUEL SYSTEM! BUY CLEAN
FUEL AND KEEP IT CLEAN ! FUEL SPECIFICATION
DEFINITIONS
A Cetane Rating number of 40 i s cons idered low,
while a Getane Rating of 60 is cons idered high.
Your Ga se Diesel Engine is designed to operate
most efficiently with a Number 2 Diesel Fuel
having a minimum Getane Rating of 45 (45 to S5 in
cold wea- ther) . Number I Diesel Fuel with
higher Getane Ratings are not recommended because
1 . Premium Diese1 Fuels are higher in price,
but will not materially increase engine
performance and therefore res ult in high
operating costs .
2 . Number 2 Die sel Fue1s with a Cetane Rating
of 45 to 50 are widely distributed and are
more readily available .
The definitions of the following terms used
in describing the fuel specifications , will be
useful for reference when selecting a suitable
Diesel fuel.
SULPHUR
POURPOINT Pour point is especially important for
cold weather operation because
Sulphur content is the percentage of corros ive
sulphur in the Die se1 Fuel .
A high sulphur content (above 0 . 4) in Die sel
Fuel is always undesirable, but it is especially
harmful when the engine must be operated in
cold weather, intermittently, or with varying
loads where it is difficult to keep operating
temperature up to the recommended level. These
types of operations re- sult in moisture
condensation in the engine which unites with
the sulphur to form destructive acids . High
sulphur content in the fuel will cause
POUR
I . Exces sive engine wearl
2. Formation of harmful deposits on valves,
rings , pistons, and cylinder sleeve walls
NO POUR
3. Pos sible corrosive damage to the fuel

EXTRA HEAVY DUTY MOTOR OIL To keep the engine
free of harmfo. seposits and to counteract any de
s- tructive acids .nat may be formed, ari Extra
Heavy Duty", additi v-type , crankcase oil must
be used . Use a good greSe crankcase oil
meeting A.P.I. ser- vice designation DS (Series
3) under all types of operating condiions .
SULPHUR CONTENT A high sulphur content in the
fuel is es pecially injurious to the engine when
it is operated intermittently or with the coolant
tempera- ture below the recomme nded operating
temperature . The moistures condensation that
forms during cold weather operation, combine s
with the sulphur in the fuel to form corros ive
acids which attact the finely machined surface s
. To eliminate pos sible acid dam- age ( 1) U
se Diesel Fuel with a sulphur content of 0. 4
or les s (2) Keep engine operating
temperature up to recommended level (3) Always
use Service DS (Serie s 3) Motor Oil.
ASH Ash is the percentage of harmful non-
combustible material in the Diesel fuel. A fuel
containing a higher maximu. a sh content than 0
. 01 can damage the extremely c.use fitting
parts in the fue l injection s ys tern .
WATER CONTENT Special precautions must be taken
to prevent the entry of water into the fuel s
ystem

• 1 . Always refill tire fuel tame . at the end of
  each day's operation to prevent water
  condensation inside the tank
• The drain on the filter should be opened daily
  be- fore s tasting the e nqine to remove any
  accumu- lated water.
• Fuel must be allowed to settle in storage for
  at lea st 24 hours before putting it into the
  Tractor s fuel tank .

FUEL HANDLING AHD STORAGE
The handling of Diesel Fuel presents a special
problem because the specific gravity of this fuel
is relati ve1y close to that of water, abras ive
rust, and dust particles. This allows these
contaminants to remain in sus pension in the fuel
for long periods of time . For this reason,
Diesel fuel must be allowe d to settle for at
least 24 hours without being disturbed in any
way, before it is put into the fuel tank .

U se a rust proof storage tame s imilar to the
illus- tration above . This tank should be
equipped with a pump, so the Die sel fuel can be
transferred directly from the storage tank to
the Tractor fuel tank.
4. When emptying a drum of fuel oil, agitate it
as little as poss ible and leave about one inch
of fuel in the bottom of the drum, which may
con- tain sediment or water.
The hose from the pump should be equipped with a
nozzle, so the contamination of the fuel by the
use of dirty buckets or funnels can be eliminated
.
Allow the fuel to settle during the night, so
that contaminants will be drained off each
morning when the sediment bowl is drained,
before starting the day's work. See Figure 24
for location of the filter.
CLEAftIHG FUEL STORAGE TANKS Drain all remaining
fuel from the tank. Use a mixture of one part a
lcohol and one part benzol, or use acetone to
dis solve the deposits in the tanit . P-lush the

directly strikes the tank will form cum more
rapidly than fuel stored in a cool place where
the temperature remains cons tant.
clean out gum and varnish depos its already in
an engine and, when used regularly, will preve nt

The following "Gase Diesel Fuel Conditioner"
recommendations are made for areas troubled
with gum or varnish in the fuel
