HOW TO DETERMINE A METERING ROLL PROBLEM

To determine if the metering prob- lem is from blockage, perform the following test with the power off. Remove the drive chain by loosen- ing the motor mounting bolts. Refer to photo, and place a pipe wrench on the hub of the roller chain sprocket, on the left hand metering roll at the drive end of the dryer. Apply up to 100 ft. lbs. of force, and attempt to rotate the roll toward the inside of the dryer. If the metering

roll will turn, then repeat for right hand side. If metering roll will turn, it can be assumed that no blockage exists, and the problem is from some other cause. Check for a break in the power train, chain, drive key, pin, etc.

CAUTION: Keep hands away from sprocket teeth to avoid injury from chain backlash, as a result of torsion build up in the system caused by the jam.

Place a pipe wrench on the hub of the sprocket of the jammed meter- ing roll and turn the roll. First back- ward, 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. Shut down the fan heater and eliminate any other

noise when making this check. Once the location is determined, the roll can be reached from the outside by open- ing the access door to remove the for- eign object causing the jam (before opening doors see below). The ser- vice tool must be inserted before open- ing doors. First, swing open the ple- num bottom closure panel. Insert service tool above metering roll.

The auger discharge switch.

SERVICE TOOL

This column cutoff damper is designed to insert through the grain column (from the inside of the dryer) immediately above the metering roll. This permits opening of the metering roll access door. For service or inspec- tion without unloading the dryer, the plenum bottom closure panel and metering roll adjust damper must be removed prior to using service tool.
