Removing From Storage; Storing The Tractor - International Harvester Company CUB Operator's Manual

STORING THE TRACTOR
mixture of one-half kerosene and one-half
SAE-IOW engine oil.
Note: Gum will eventually form in the fuel
tanks, lines, and carburetor if the unit is notused.
Gum in carburetor jets and passages
affects engine starting. Gum can be dissolved
with commercial carburetor cleaner.
4. Remove the spark plugs and pour a mix-
ture of one-half gasoline and one-half light
lubricating oil into each cylinder; one ounce
(two tablespoonfuls) per cylinder is enough.
4. Drain the fuel from the fuel tank and
carburetor, and clean out the fuel strainerglass
bowl.
5. Crank the engine rapidly until excess
oil has been blown out of the spark plug holes.
This operation will loosen any tight piston
rings and wash old, gummy oil from the valves
and pistons.
5. After the engine has cooled off, remove
the spark plugs and pour one tablespoonful of
SAE- 50 lubricating oil of good quality into each
cylinder. Crank the engine two or three timesto
distribute the oil over the cylinder walls.
Then replace the spark plugs.
Omit steps 6, 7, and 8 if they were per-
formed before the tractor was stored.
6. Drain the crankcase and flush it out
with kerosene or flushing oil and fill with spec-
ified lubricating oil. See the " Lubrication
Guide".
Drain and flush the cooling system.
7. Tractors with Magneto: Oil the magneto im-pulse
coupling liberally with very light oil,
such as cream separator or sewing machine
oil.
7. Be sure the lubricating oil filter has a
new element before starting the engine.
8. Clean the air cleaner and refill the oil
cup.
8. Remove the valve cover and slush thevalves,
rocker arms, and push rods with
SAE-50 oil. (If any evidence of rust is found,
remove it before lubricating.) Use a paint
brush to coat the inside of the valve cover
with SAE- 50 lubricating oil. Replace the valve
cover.
9. !nst/all the spark plugs after cleaning and
setting the gaps.
10. Fill the cooling system. Be sure the
cooling system has a rust inhibitor added to it.
9. Remove the oil filler breather cap and
oil level gauge. Then plug the oil filler pipe.Also
plug the exhaust pipe.
11. Fill the fuel tanks.
Caution! Do not accelerate the engine rapidly,
or operate it at high speed immediately after
starting, Also keep the doors wide open or
move the machine outside the storage room
immediately to avoid danger from exhaust gas.
10. Remove the battery and place it on a
rack or bench in a cool, dry place above freez-
ing (+320 F.). Check the battery at least once
a month for water level and specific gravity.
11. Block the clutch pedal with a wood
block so that the ciutch is disengaged. This
will prevent the clutch facing from sticking tothe
flywheel or clutch pressure plate.
12. Start the engine and let it run slowly.
If a valve is sticking, pour a small quantity ofkerosene
on the valve stem until it is loose.
Assemble the valve cover.
REMOVING FROM STORAGE
14. After the engine has been run long
enough to clean the excess oil out of the cylin-ders,
the spark plugs should be removed and
checked for oil fouling. If fouled, clean and
reinstall them in the engine.
1. Remove the plugs from the crankcase
breather
cap, the breather pipe and the ex-
haust pipe.
2. mstall a fully charged battery and be
sure the proper connections are made. See
Illust.2SA.
15. Remove the block from the clutch pedal.
3. Remove the valve cover and slush thevalve
and valve operating mechanism with a
16. Before driving the tractor, inflate the
tires to the correct operating pressures.
