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.
