Wheel Shear Bolts:
We included two extra shear bolts with your DR® Powerwagon™ 4 x 2. These are meant to
shear before damage can be done to the transmission. If you find that only one wheel is
driving or hear rattling from the rear wheel hubs you may have broken shear bolts. These are
easy to replace. You will need a 14 mm wrench or socket and an 8 mm Allen wrench.
Always disconnect the spark plug wire
before servicing.
• Remove the wheel hubcap by removing the
bolt in the center.
• Rotate the wheel slightly to take the tension
off the bolts. The inner hub is slotted. The
bolts should be away from either end of the
slots.
• If the old bolts are no longer attached, find
the through hole and install the new bolts as
shown in Figure 18.
Fuel Filter and System:
Always disconnect the spark plug wire before servicing.
The fuel line runs from the valve on the fuel tank to a fuel filter. The line runs from the filter
to the engine. There are no user serviceable parts in the filter and it should be replaced every
200 hours, or when it becomes clogged.
Caution: Do not smoke or allow others to smoke or have any sparks or other
sources of ignition near by while filling the gas tank or servicing the fuel system. Only
fill the tank outdoors.
To determine if the filter is clogged, close the valve under the tank. Have a suitable container
handy to catch the fuel. Disconnect the fuel line from either the engine or engine side of the
fuel filter. Put the end of the hose in the container and turn the tank valve on. Fuel should
flow freely through the filter into the container. Remember that the fuel system is gravity fed
and the hose should be lower than the tank.
Your engine does not have a fuel pump and fuel flows only because the tank is higher than the
carburetor.
• Always use fresh, regular gasoline with a minimum 85 octane.
• Only buy gasoline in quantities that you will use up in one month. Gasoline can become
stale and can cause poor engine performance.
• At the end of the season empty the gas tank, and run the engine until it runs out of gas.
This will help keep the carburetor from getting gummed up.
