Engine Oil; Engine Maintenance - Craftsman 247.88852 Owner's Manual

Lubrication
For a view of the lubrication points on the snow
thrower, see Figure 19.
Sprocket Shaft
• Lubricate the sprocket shaft with grease at least
once a season or after every 25 hours of
operation.
IMPORTANT: Keep all grease and oil off of the
friction wheel and the drive plate.
Shifting Mechanism
• Lubricate the shifting mechanism and pivot
points on the shift rod with engine oil at least
once a season or after every 25 hours of
operation.
Traction Drive Control
• Lubricate cams on the ends of the control rods
which interlock the traction drive and auger
controls at least once a season or every 25
hours of operation with grease. The cams can be
accessed beneath the handle panel.
Gear Case
• The gear case is lubricated with grease at the
factory and does not require checking. If
disassembled for any reason, lubricate with two
ounces of Shell Alvania grease.
Bearings
• Once a season lubricate the auger bearings and
the bearings on the side of the frame with light
oil. See lube chart below.

Check V-belts
Follow the instructions below to check the condition
of the drive belts every 50 hours of operation.
• Remove the plastic belt cover on the front of the
engine by removing two self-tapping screws.
• Visually inspect for frayed, cracked, or
excessively worn out belts.
Check Friction Wheel
Follow the instructions below to check the condition of
the friction wheel rubber every 25 hours of operation.
• Remove the six self-tapping screws from the
frame cover underneath the snow thrower.
• Visually inspect the friction wheel rubber for
excessive wear, cracks, or loose fit on the
friction wheel drive hub.
• Also engage traction drive control and check if
the friction wheel is making contact with the
friction plate.
• If it does not make contact, adjust the traction
drive cable following instructions and . Recheck
the friction wheel.
• Replace friction wheel rubber if necessary.
Refer to instructions on page 23.

Engine Maintenance

Engine Oil

Only use high quality detergent oil rated with API
service classification SF, SG or SH. Select the oil's
SAE viscosity grade according to the expected
operating temperature.
colder
5W30
Viscosity Chart
NOTE: Although multi-viscosity oils (5W30, 10W30
etc.) improve starting in cold weather, these multi-
viscosity oils will result in increased oil consumption
when used above 32
engine oil level more frequently to avoid possible
engine damage from running low on oil.
Refer to the viscosity chart for proper selection of
engine oil.
Checking Oil Level
Before operating the snow thrower, check the oil
level.
• With engine on level ground, the oil must be to
FULL mark on dipstick.
• Stop engine and wait several minutes before
checking oil level. Remove oil fill cap and
dipstick.
