4. Before removing the oil filter, clean the area around
the filter to keep dirt and debris out of the engine.

5. Remove the old oil filter and wipe off the filter
mounting surface on the engine.
6. Apply a thin coating of clean oil to the rubber
gasket on the replacement oil filter.
IMPORTANT: Use ONLY oil filters from the engine
manufacturer. Aftermarket oil filters may not seal
properly and/or may not have the correct pressure
relief valve for proper lubrication. Also, for certain
models the
filter length dimension is critical for
tailwheel clearance.

9. Fill the crankcase through the oil filler tube (dip-
stick opening) with new, clean oil. Use only
crankcase lubricants recommended by the engine
manufacturer. Refer to
Specifications
in this
manual or the engine owner’s manual. Use the
recommended oil viscosity for the expected ambi-
ent temperature. Oil with the correct viscosity will
aid starting in cold weather and assure proper lu-
brication in hot weather.
Fill up to, but not
above, the “F” mark on the dipstick. Crankcase
capacity is 1.85 quarts (1.75 liters) plus 1/2 pint
(.24 liters) for the new oil filter.
Model MD
9. Fill the crankcase with new, clean oil. Use only
crankcase lubricants recommended by the engine
manufacturer. Refer to
Specifications
in this man-
ual or the engine owner’s manual. Use the recom-
mended oil viscosity for the expected ambient
temperature. Oil with the correct viscosity will aid
starting in cold weather and assure proper lubrica-
tion in hot weather.
Fill up to, but not above, the
upper mark on the dipstick. Crankcase capacity
is 3.1 quarts (2.9 liters) plus 1/2 pint (.24 liters) for
the new oil filter.
IMPORTANT: DO NOT use oil that is rated for gas-
oline engines only (API SE/SF). This will cause
problems with a diesel engine.
Model MS
9. Fill the crankcase (through the dipstick opening)
with oil using only crankcase lubricants supplied
by the engine manufacturer. Refer to
Specifica-
tions in this manual or the engine owner’s manual.
Use the recommended oil viscosity for the ex-
pected ambient temperature. Oil with the correct
viscosity will aid starting in cold weather and as-
sure proper lubrication in hot weather.
Fill to
FULL (H) mark on the dipstick; crankcase capac-
ity is 2.7 pints (1.3 liters).
