The Countersink measurement should be approximately equal to the thickness of the Seaming Chuck flange to a maximum of approximately .005 of an inch greater than the thickness of the Seaming Chuck flange.
|Probable Cause||Suggested Remedy|
|Excessive clearance of 1st operation seaming roll above the seaming chuck||Reset 1st Operation Seaming Roll height to within a maximum of .003 of an inch over the Seaming Chuck flange when it is at its furthest inward travel. A lesser amount is desirable providing that the Seaming Roll doesn’t drag on the Seaming Chuck during its operation|
|Diameter of the Seaming Chuck greater than covers used||Replace the Seaming Chucks|
|Seaming Chuck flange thickness is too great.||Replace the Seaming Chucks with the proper thickness|
|Worn 1st Operation Seaming Roll||Replace the 1st Operations Seaming Rolls. See Parts List Instructions or Service Manual for this procedure.|
