SECTION 3
D. Belt Replacement
Ensure the kart is on a smooth flat surface and the engine is OFF. Apply parking brake. Remove the three mounting bolts for the belt cover. Remove
mounting screw located behind the belt cover at the bottom. Using a ½" socket or box wrench, remove the driver (front) pulley mounting bolt and pull
the pulley off the crank shaft. To prevent the engine crank shaft from turning with the pulley mounting bolt, use a strap wrench around the pulley outer
stationary sheave. If the existing belt is still intact, remove it. If not, look for anything that may have caused the belt to fail prematurely. Inspect pulley
and perform clutch lubrication and cleaning (Section E). Install new belt with the tapered edge away from the engine (Arrow pictured on belt will point
TOWARD THE ENGINE). Place belt around the driven (rear) pulley and stretch over the crank shaft and onto the bronze bushing. Replace the driver
pulley and mounting bolt. Tighten bolt to 30 ft*lb
E. Driver Pulley Lubrication and Cleaning
The driver pulley may perform poorly if not lubricated properly within each 25 hour period. Premature failure of its components may also occur. Before
reaching 25 hours of operation, remove the driver pulley from the engine output shaft paying close attention to how all the components nest with
each other inside the driver pulley. Disassemble the components of the driver pulley. Using brake or carburetor cleaner and a soft brush, clean all
the components of the assembly. Ensure there are no rough surfaces. Apply a dry graphite lube to the entire outer surface of the hub and the inner
surfaces of the outer stationary sheave. Allow the lube to dry completely. Reassemble the driver pulley and install onto the engine output shaft.

F. Storage Instructions
If you plan to store (and not operate) your kart for a period in excess of 30 days, or at the end of each driving season, the unit should be set up for
storage as follows:
1) Drain fuel tank and carburetor by allowing the engine to run until the fuel system is dry.
2) Lubricate the engine cylinder by removing the air cleaner and by spraying an engine fogging oil through the carburetor.
3) Do NOT save or store gasoline over the winter. Using old gasoline, which will deteriorate from storage, will make the engine difficult to start and
affect the performance of the engine.
4) To protect the paint, plastics and upholstery, it is a good idea to keep the unit covered when not in use.
G. Front Wheel Replacement
Remove cotter pin and castle nut. Wheel should be easily removed. After
replacing the wheels, tighten castle nut and replace cotter pin with a new one.
