Removal
1. Stop engine and wait for all moving parts to stop. Pull
wire off spark plug (Fig. 15).
2. Remove capscrew, wheel spacer, and locknut
mounting wheel to pivot arm.
3. Separate wheel halves from tire by removing (4)
capscrews and locknuts.
Note: If bearings are to be removed from bearing/hub
assembly, remove by pressing on bearing spacer.
Assembly
1. Position tire onto (1) wheel half aligning lugs on each.
2. Place bearing/hub assembly into center hole of wheel
half. Make sure legs of hub are positioned over flange
of hole.
3. Place other wheel half onto bearing/hub assembly,
aligning wheel and tire lugs and mounting holes.
4. Using (2) 6 mm x 38 mm (1/4—20 x 1.50") fully
threaded screws or bolts and non–locking nuts, loosely
secure wheel halves together. Mount screws or bolts in
opposing holes.
5. Check alignment of all parts and tighten screws,
alternating from side to side for a uniform fit, until
wheel halves are drawn together.
6. Install (2) capscrews and locknuts, previously
removed, in remaining holes in wheel halves and
tighten. Remove (2) long screws or bolts and replace
with (2) capscrews and locknuts.

wheel hub and pivot arm.

Fuel Filter

Replacing the Fuel Filter
Replace the fuel filter after every 100 operating hours or
yearly, whichever occurs first. The best time to replace the
fuel filter (Fig. 34) is when the fuel tank is empty. Never
install a dirty filter if it is removed from the fuel line.
1. Squeeze the ends of the hose clamps together and slide
them away from the filter (Fig. 34).

2. Remove the filter from the fuel lines.
3. Install a new filter and move the hose clamps close to
the filter.
Note: The flow arrow on the filter must point toward
the carburetor.

Preparing Mower For Storage

1. For long term storage, either drain gasoline from fuel
tank or add a fuel stabilizer to the gasoline. To drain
gasoline, refer to Draining Gasoline, page 15. After
fuel is drained, start engine and let it idle until all fuel
is consumed and engine stops. Repeat the starting
procedure two more times to assure all gas is removed
from the engine. If gasoline is not drained, gum–like
varnish deposits will form and cause poor engine
operation, even starting problems.
Fuel can be left in gas tank only if a fuel additive, such
as Toro's Stabilizer/Conditioner, is added to gasoline
and run through engine before storing. Toro's
Stabilizer/Conditioner is a petroleum distillate based
conditioner/stabilizer. Toro does not recommend
stabilizers with an alcohol base, such as ethanol,
methanol or isopropyl. Use fuel additive in
recommended quantities as specified on container.
Under normal conditions, fuel additives remain
effective in fuel for 6-8 months.
