Craftsman 247.888530 - Manual (Page 18)

Wheels
• Oil or spray lubricant into bearings at wheels at
least once a season. Pull klick pin, remove wheels,
clean and coat axles with a multipurpose
automotive grease. See Figure 23.
Figure 23
Traction Control / Auger Control Lock
The cams on the ends of the control rods which
interlock the traction drive and auger drive clutches
must be lubricated at least once a season or every 25
hours of operation using a multi-purpose automotive
grease. The cams can be accessed beneath the handle
panel. See Figure 24.
Gear Shaft
• Lubricate the gear shaft with 6-in-1 grease (part
number 737-0170) at least once a season, or after
every 25 hours of operation.
IMPORTANT: Keep all grease and oil off the rubber
friction wheel and drive plate.
Gear Case
The gear case is lubricated with grease at the factory
and does not require further lubrication regularly.
• However, if disassembled for any reason, lubricate
with 2 ounces of Shell Alvania™ grease EPROO,
part number 737-0168. Before reassembling,
remove old sealant and apply new sealant.
IMPORTANT: Do not overfill the gear case, since
damage to the seals could result. Be sure the vent plug
is free of grease in order to relieve pressure.
Check V-Belts
Follow instrcutions 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 the traction controi and check if the
friction wheel is making contact with friction plate. If
it does not make contact, adjust the traction drive
cable and recheck the friction wheel.
• Replace friction wheel rubber if necessary. Refer to
instructions on page 23.
• After maintenance on friction wheel is over, re­
attach the frame cover to the snow thrower with the
hardware removed earlier.
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.

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°F. Check your snow thrower’s
engine oil level more frequently to avoid possible
engine damage from running low on oil.
