[GreenKeys] Model 19 gears

[Nick]

I experienced the same problem with one of my 15's. Took the basket of and soaked it for a few hours in Simple Green. After that, the entire mechanism was moving freely. Having said that, it's always a good idea to let a cleaning solution do the job before using force in order to free up any mechanism.

I also had gummed up ribbon mechanisms on my 15 and 19, but I ended up not having to take them apart. It took oiling them and working them by hand for quite some time, but now they move pretty freely. That being said, I could move them by hand with a relatively high amount of force from the beginning, but if yours are completely frozen and cannot be turned by hand at all, you may need to disassemble and clean. Heck, it's probably best to disassemble and clean regardless. I'm just lazy.

Definitely be careful not to break the mechanism when trying to move by hand with force.

I don’t remember if you said that the ribbon advanced when you took the basket off or not.  If not… I got a basket from one of the kind folks here on greenkeys since both of mine were either for weather or finance ;p .  Anyways, what I ended up having to do was to disassemble both mechanisms that advance the ribbon.  They were totally gummed from either old oil, old ink or grime… probably all three.  Nothing took care of it while it was all together - mineral spirits, nothing.  If you have to go down that route, please be very careful because I ended up breaking off one of the… whatever they are called and had to use a spare off of another ;p .  A cloth, rubber mallet, vice grips, flat head screw driver, mineral spirits, more, etc… it took a good few hours to “pry” (not so much pry) all those parts out and clean them.  Very much good luck if that’s what your going to have to do in the end ;o ~

The clutch "appeared" to be working but I applied liberal doses of oil to it and to the area underneath the magnets.  I also removed the cap at the end of the main shaft and dripped oil down the center.  I put the typing unit back on the machine, hooked everything up, called up ITTY, and let it start printing.  This time after a few lines it started copying mostly correctly.  The LF had not been working before and it began working as it should.  The typing basket had been advancing only about half-way down a line and now it is going to the proper end. CR & LF seem to be working as they should.  It is typing pretty well so it is obviously 60wpm.  The only "major" problem now is that the ribbon isn't advancing and returning so it just types until it pounds a hole in the ribbon.  I'm going to let it run open for awhile and see if that jars the mechanism loose.  I had put quite a lot of oil on the typing basket/head so it "should" be well lubricated.  There must be some residual guminess somewhere.
