Oil Head Timing Belt: This belt should be adjusted a little on the tight side.
Unplug the head motor fuse before attempting to work on this belt to disable the
braking circuit.
To adjust head belt tension, loosen the 4 screws in the
slotted bracket, adjust the belt so that when you push the
belt down from the top it just touches the head bar
assembly as shown in the below figure.
Fasten all screws when done. This belt drives the
board counting disk and the cleaner assembly making
it important that the belt not run loose. A loose belt
can cause the machine to lose its oil head timing and
the timing that controls the movement of the cleaner
head.
Replace fuse when belt tension is correct and
fasteners are tight.
Oil Pump Belt
It is important to run the oil pump belt on the loose side. Over-tightening of this belt will
reduce bearing life in the pump and cause premature failure of the oil pump motor. This
may also cause oil volume fluctuations. Loosen up the oil pump motor fasteners to change
belt tension.
