Replacing The Auger/Impeller Drive Belt; Changing The Engine Oil; Lubricating The Snowthrower - Toro 38063 Operator's Manual

4. Connect the wire to the spark plug.
5. Check the belt tension by operating the auger.
6. If the belt still slips, replace it. Refer to Replacing the
Auger/Impeller Drive Belt on page 23.
Important
Do not operate the snowthrower if the auger
and the impeller rotate when you disengage the
auger/impeller drive control lever.
Replacing the Auger/Impeller
Drive Belt
If the auger/impeller drive belt becomes worn, oil-soaked,
or otherwise damaged, replace the belt.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the plug (Fig. 15).
3. Remove the two flange-head bolts that hold the belt
cover in place and set the cover aside (Fig. 23).
4. Loosen the belt guide (Fig. 24).
5. Remove the auger/impeller drive belt from the engine
pulley and the large auger/impeller pulley (Fig. 24).
6. Install a new belt around the large auger/impeller pulley
(Fig. 24).
7. Loop the belt over the engine pulley, ensuring that the
belt is on the inside of the idler pulley and the belt guide
(Fig. 24).
8. Adjust the belt guide so that there is 1/8 inch
(3 millimeters) of clearance between the auger/impeller
drive belt and the guide, and secure the belt guide.
9. Check and adjust the auger/impeller drive belt as
instructed in steps 4 through 7 of Installing the
Auger/Impeller Drive Control Linkage on page 10.
10. Install the belt cover.
11. Connect the wire to the spark plug.
Important
Do not operate the snowthrower if the auger
and the impeller rotate when you disengage the
auger/impeller drive control lever.

Changing the Engine Oil

Change the engine oil after the first two operating hours,
after every 25 operating hours, and at the end of the
snowthrowing season. If possible, run the engine just
before changing the oil because warm oil flows better and
carries more contaminants.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the spark plug (Fig. 15).
3. Block up the rear of the snowthrower.
4. Remove the left wheel.
5. Clean the area around the oil drain plug (Fig. 27).
1. Oil drain plug
6. Slide an oil drain pan below the drain extension and
remove the oil drain plug (Fig. 27).
Note: Place a funnel under the drain extension so the oil
drains directly into the oil drain pan and away from the
snowthrower.
7. Drain the oil.
8. Install the oil drain plug.
9. Install the left wheel.
10. Fill the crankcase with oil. Refer to Filling the Engine
Crankcase with Oil on page 12.
11. Wipe up any spilled oil.
12. Connect the wire to the spark plug.

Lubricating the Snowthrower

Lightly lubricate all moving parts of the snowthrower after
every 15 operating hours and at the end of the
snowthrowing season.
Important
Do not get oil or grease on the rubber wheel
or friction drive plate because the wheel will slip and the
rubber may deteriorate.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug and ensure that
the wire does not contact the plug (Fig. 15).
3. Drain gasoline from the fuel tank. Refer to Emptying
the Fuel Tank on page 24.
4. Tip the snowthrower forward onto the auger/impeller
housing and block it so that it cannot fall.
