How to Clear a Jammed Metering Roll
Shut down the fan/heater and eliminate any other noise when making this check. Place a pipe wrench
on the hub of the sprocket of the jammed metering roll and turn the roll. First backward, and then forward
several times in an attempt to dislodge the object, and clear it through the roll. If this is not successful,
have an assistant turn the metering roll, and attempt to locate the jam by sound. Once the location is
determined, the roll can be reached from the inside of the dryer by opening the hinged auger cover panel
in that specific section. Loosen the two (2) nuts on the bolts holding the meter roll shield (also called
meter roll strike off Plate in the past) and lift the shield to access the area above and behind the meter
roll. If removing all the grain from this column is necessary, lift the shield to its highest position and
tighten the nuts. FROM OUTSIDE THE DRYER, manually run the Unload Auger with the MOISTURE
CONTROL switch turned OFF and the high speed potentiometer set to 000. This will allow the grain from
that column alone to pass over the metering roll and into the auger emptying that column for complete
access to the meter roll.
Never run the unload auger or the metering rolls with anyone inside the dryer.
