4. Separate the wheel halves from the tire by removing
four cap screws and four locknuts (Fig. 36).
Note: If you remove the bearings from the bearing/hub
assembly, remove them by pressing on the bearing spacer
(Fig. 36).
Assembling the Wheels
1. Position the tire onto one wheel half, aligning the lugs
on each (Fig. 36).
2. Place the bearing/hub assembly into the center hole of
the wheel half. Ensure that the legs of the hub are
positioned over the flange of the hole (Fig. 36).
3. Place the other wheel half onto the bearing/hub
assembly, aligning the wheel and the tire lugs and the
mounting holes (Fig. 36).
4. Using two 1/4–20 x 1-1/2 in. fully threaded screws or
bolts and non-locking nuts, loosely secure the wheel
halves together. Mount the screws or bolts in the
opposing holes (Fig. 36).
5. Check the alignment of all parts and tighten the screws,
alternating from side to side for a uniform fit, until the
wheel halves are drawn together (Fig. 36).
6. Install the two cap screws and two locknuts previously
removed in the remaining holes in the wheel halves and
tighten. Remove the two long screws or bolts and
replace them with two cap screws and two locknuts
(Fig. 36).
7. Install the wheel to the pivot arm with the cap screws, a
spacer, and a locknut. Ensure that the spacer is
positioned between the wheel hub and the pivot arm
(Fig. 36).
Emptying the Fuel Tank
1. Stop the engine and wait for it to cool down.
2. Disconnect the wire from the spark plug (Fig. 9).
3. Remove the cap from the fuel tank.
4. Use a hand pump to syphon the fuel into a clean,
approved fuel container.
5. Connect the wire to the spark plug.
6. Run the engine until it stops.
7. Start the engine again to ensure that all the fuel is out of
the carburetor.
