SECTION IV. MAINTENANCE
ENGINE OIL
The engine crankcase is filled with ship-away oil. This
oil may be used for the first 5 hours of engine opera¬
tion at temperatures between 0® and 90°F. If tem¬
peratures are not within this range, drain the oil from
the oil filter and crankcase and replace with new oil as
specified in the "LUBRICATION TABLE."
To aid starting, the selection of crankcase lubricating
oils should be based on the lowest anticipated tem¬
peratures until the next drain period.
Cub Cadet
Low Ash Engine Oil meeting API Service
Classification SF or SG is recommended. For max¬
imum engine life select API SF or SG oils with lowest
levels of barium, calcium or magnesium additives and
minimum ash content (approximately 0.5%). Lubri¬
cant suppliers will normally furnish this information on
their engine oils.
For oil change intervals of 50 hours the following oils
are recommended.
32°F and above —
Cub Cadet
Low Ash Engine Oil
S.A.E. 30W
0°F to 32°F —
Cub Cadet
Low Ash Engine Oil
S.A.E. 10W-30
Below 0°F —
S.A.E. 5W-20 or S.A.E. 5W-30
For other approved oils refer to "LUBRICATION
TABLE."
■^NOTE
For temperatures above 32°F a multi¬
viscosity oil 10W-30 or 10W-40 can be used.
When either o! these oils Is used, the oil
change Interval Increases to every 25
hours.
Regularly check the oil level of the engine
crankcase to see that it is filled to the correct
level. Always keep the oil level between the
"FULL" and the "LOW" marks on the dip¬
stick. When checking the oil level, engine
must be cold, the dipstick must be with¬
drawn and wiped clean, then inserted all the
way and withdrawn for a true reading.
Check the oil level only while the engine is
stopped and tractor is level.
During initial break-in period the engine oil
level should be checked frequently.
FILLING THE CRANKCASE
To fill the crankcase with oil, place the tractor on a
level surface. Clean the area around the oil fill tube
and dipstick to prevent debris from entering the
crankcase. Remove the oil fill cap and slowly pour 3
pints of oil into the crankcase. Replace the oil fill cap.
The 18-HP and 20-HP engine is equipped with a
remote oil filter; it is necessary to run the unit for
approximately one minute to allow the oil to fill the
filter and oil lines. After stopping the engine remove
oil fill cap and add the remaining 8 ounces of oil, pour¬
ing slowly. (Engine oil capacity — 3 pints 8 ounces.)
When checking the oil level, push the dipstick assem¬
bly firmly but slowly until cap bottoms on tube. DO
NOT OVERFILL.
Dipstick assembly MUST BE
PUSHED FULLY INTO TUBE AT ALL TIMES WHEN
ENGINE IS OPERATING.
■^NOTE
Never overfill the engine crankcase. Engine
may overheat and/or damage may result if
the crankcase is below the "LOW" mark or
over the "FULL" mark.
OIL FILTER
The oil filter is located behind the right side panel and
is mounted to the baffle. (See Figure 31.) The oil
filter should be changed at every oil change interval.
