Filling The Crankcase; Adding Transmission Oil; Checking Transmission Oil Level - Cub Cadet LT 2138 Operator's Manual

FILLING THE CRANKCASE

CAUTION
Never overfill the engine crankcase. The engine
may overheat and/or damage may result if the
crankcase is below the "LOW" mark or over the
"FULL" mark on the dipstick. For best results, fill
to the "FULL" mark on the dipstick as opposed
to adding a given quantity of oil. Always check
the level on the dipstick before adding more oil.
Refer to the LUBRICATION TABLE for information
regarding the oil capacity and the proper type of oil to
pour into the crankcase.
1. Place the tractor on a level surface and engage the
brake pedal lock. Stop the tractor engine and
remove the ignition key.
2. Clean the area around the oil fill tube and oil fill
cap/dipstick to prevent debris from entering the
crankcase.
3. Remove the oil fill cap/dipstick from the oil fill tube
and SLOWLY pour oil into the fill tube. The oil
capacity is approximately 4 pints. Fill the
crankcase until the oil level reaches the "FULL"
mark on the dipstick (Refer to Figure 18).
4. Reinstall the oil fill cap/dipstick securely into the oil
fill tube
CAUTION
The oil fill capdipstick MUST BE INSTALLED
SECURELY INTO THE TUBE AT ALL TIMES
WHEN THE ENGINE IS OPERATING. Severe
engine damage could result from failure to do so.
5. Start the tractor engine and allow it to run for 30
seconds, then stop the engine and remove the
ignition key.
6. Check the oil level and add oil if necessary. DO
NOT OVERFILL THE ENGINE CRANKCASE.
7. Check the oil filter and drain plug for leaks.

CHECKING TRANSMISSION OIL LEVEL

NOTE
Check the oil level only while the engine is
stopped and the tractor is level.
Check the oil level of the transmission case before
each use to see that it is filled to the correct level.
Before checking the transmission oil level, clean the
area around the oil fill plug/dipstick to prevent debris
from entering the transmission case. Always keep the
oil level between the "FULL" and the "ADD" marks on
the dipstick (See Figure 20). When checking the oil
level, the dipstick must be withdrawn and wiped clean,
then inserted all the way before being withdrawn for a
true reading.
