I’ve got a 111w155 with the end of the arm shaft bent and the end wheel busted, evidently someone dropped it, does anyone have or know where I can get instructions on how to replace it? I’ve got a new hand wheel, arm shaft and bearing ordered but I haven’t been able to get the old shaft out yet. Any help would be appreciated.

You're kind of on your own. I never found a good disassembly and re-assembly manual.  That said I completely disassembled and re-assembled my 211 (new version of the 111). It's not that hard.   I'd take pictures of everything before I took anything off

1 - Line up the take up arm to it's highest point and note which Letter the timing belt is set to in the bottom.  Some manuals say line up on A, some on B. You want to know before you take it apart. 

2 - The upper shaft is sandwiched between the hand wheel and a counterweight on the other end of the machine.  My counterweight had 2 set screws into the shaft.  You ought to be able to release these set screws to release that end of the shaft.  It's very similar to replacing the take up arm so, you might look at those instructions. 

3 - Note the position of the clutched thing that drives the walking foot. Getting that timed properly took me the most time and I'm still not sure it's exactly right.  Maybe see where it is in relation to the timing marks before you pull the belt.

4 - That spring loaded clutch thing that moves the walking feet has set screws into the shaft (I'm assuming the 111 is the same as the 211 here). There's two set screws which aren't the two next to pan head screws.  There might be a spacer on the shaft on the needle side of this thing. It's got a set screw too. 

5 - There's a set screw in the thing on the shaft that drives the bobbin winder (if yours is on top like the 211). 

6 - The upper timing gear has two set screws into the shaft. One deep and one shallow. You need to note their position when you take them out. 

With all that loosened up, you ought to be able to slide the shaft out the hand wheel side.  I found that if the foot driver spring retainer is too tight, it can squeeze the shaft. If you loosen them and the spring comes out, you'll probably have to pull the mechanism out of the machine and get the spring retainer back on on a bench. The spring is quite strong. 

This was just my experience taking one apart. There might be an easier way.  I don't believe the timing gear will go through the casing so, the shaft has to be pulled through the gear.  

The shaft was  keyed at the timing gear and at the counterweight that drives the takeup arm and needle side.  The thing that drives the walking feet wasn't keyed. The manual seems to suggest you just eyeball it.

It's usually not real easy to get out because of the old oil,lint & dirt & sometimes corrosion buildup that will require you to sand the shaft (as much of it as you can) & you will have to keep sanding it mores it slides out more .Then try the new shaft on the bearing ,pulley & walking foot cam before trying to re-install (it require some sanding for the parts to fit) it will make it alot easier for you.
