|
Solutions |
| 1. For Door assemblies with C-clips on the hinge pin If the hinge pin is the type with C-clips on top and bottom then remove the pin and examine it for straightness by rolling it along a flat surface If the pin does not roll smoothly then replace it If the pin is okay then insert it first into the part of the hinge attached to the machine and then into the part of the hinge on the Door. The pin should move up and down smoothly. It should not be able to rock back and forth. If the pin does not move smoothly or a rocking is evident then repeat the procedure with another pin. If a new test pin is not available then use the pin from the Closing Device, making sure it is straight by first rolling it on a flat surface. If a substitute pin is not available then use the following procedure If the pin is able to rock back and forth then rotate the pin ¼ of a turn and recheck it. If the looseness disappears then replace the pin If the looseness remains then replace that part of the hinge assembly When reassembling the hinge and pin be sure to reinstall the C-clips in the grooves on the top and bottom of the pin. This can result in the inability of the Door to keep the Chamber sealed while under pressure. If the Door hanging is due to a spread that has developed between the stops on the hinge then one or two nylon or brass flat washers can be inserted between the bottom stop and the Door to lift it up. Also the hinge itself can be replaced. For Door assemblies without C-clips on the hinge pin The hinge pin without C- clips is more commonly referred to as a tapered pin or pressed pin. This type of assembly has a brass bushing in the door part of the hinge. This bushing is designed to wear out before the pin or hinge itself. And as a result it needs to be replaced from time to time. Because of ASME (American Society of Mechanical Engineers)regulations the brass bushing can only be repaired at the Tuttnauer Repair Center. In order to insure the integrity of the Door assembly there is a specific procedure outlined by ASME that needs to be followed. In addition ASME requires that this procedure be preformed only by an ASME certified shop |
