• Alternately, you can purchase gas stabilizer and add that to the fuel in the tank and then
run the engine. Follow the directions on the stabilizer.
Belt Information:
• The DR® Powerwagon™ is equipped with 2 agricultural duty belts. They are 55-inch
belts and the replacement number is 4340-0550L. They should be replaced in pairs.
• If you find that the vehicle is starting to lose speed and power, and the engine is operating
normally you may need to check the belts.
• Always check the engine operation before you adjust the belts. A dirty air filter, clogged
fuel filter, or a fouled spark plug can exhibit the same symptoms.
The belts become tight when you release the clutch pedal. A cable runs from the clutch pedal
to a support bracket. The end of the cable housing is attached to the support bracket with two
nuts. The cable wire then runs to the idler roller lever. The idler roller lever is spring-loaded at
the upper end. The spring runs from the lever to the spring support bracket and is connected
to a threaded adjustment rod. The adjustment rod is attached to the spring support bracket
with two nuts. With the clutch engaged the spring length should be 7 1/4 inches from the end
of the hook to the end of the opposite hook. With the clutch pedal pushed in the spring
should measure 7 7/8 inches. See Figure 21.
Caution: Improper belt tension can cause excessive belt wear and low power if too loose. If
the belts are too tight then it will be hard or impossible to shift gears and transmission damage
could occur.
There are two belt guides that are attached to
the engine as shown in Figure 19. These are
set at the factory and should never need
adjustment. If you find that removal is
necessary then the upper guide should be set
at 3/8 inches from the belt, and the lower
guide should be 1/4 inch from the belt. These
guides enable the belts to slip on the engine
pulley when the clutch is disengaged. Also
note that the distance between the belts at the
idler pulley should be 2 1/2 inches with the
clutch engaged. See Figure 20.
