Adding machine repair

Yes, I spotted that and sent a correction. Remember that, in general, it's the gunge that you can't see that that's the problem. Old, sticky oil and dust on the base casting will look unsightly but won't cause problems. But old, sticky oil in a pivot of one of the linkages will. And I've read plenty of books and articles that state that dunk-cleaning, even in an untrasonic cleaner ill not proberly clean out pivot holes, particularly without dismantling. A second issue is that, of course, the cleaning solvents will remove the lubrication from the mechansims. You have to re-oil everytthing. IF the unit is assembled, even with the service manual it's easy to miss some pivot point hidded well under other parts. Without a service manual you are certain to miss something. But if you take the whole thing aaper and oil the bivots and bearings as it goes back toyether you are much more likely to do every one. It's up to you, but I know I'd spend the time to take it apart Sure, but I didn;t say you hafe to take the whole thing apart at once... I have suggested removing various moduels anyway. There are others that come off too, like the receiver mechansim. Each module, and things like the keyboard and reader, can be stripped, cleanerd, and put back together in an afternoon I think. So you take a module, strip it down, clean the parts, put it back together, and put it in box until the whole machien is ready to go back together. My other tip is to buy some of thos divided plastic boxes. The Raaco ones which will decide to adjuest themselves at the wrong moment. When you take something off, put the fixing parts (screws, washers, etc) in a compartment of said box. If nevessary put in a slip of paper to indicate what the bits are. When you need to pack up, close the lid down and the parts are all safely stored. -tony
