ROTEX RM-1 Rebuild (kind of)

I think I have everything cleaned and painted. I can't really finish until I get the new bearing.

I think it will help my old eyes see the dials if I paint the lines and numbers. Anybody have a good method to do so?
The gals at work that have to do this, they use a small bottle nose container, put the paint as best you can, then swipe away the rest that is too much, with small, like a matchbook card board , squares, then wipe with a rag of acetone after a few minutes:<)


Good luck!
 
I got the motor back together and running but it had a slight noise that bothered me. I took it back apart for a look and found the bearing on the pulley end of the shaft has a rough spot.

Pulled both bearings off and found someone had been into the motor before. It has KOYO 6202 2/Z roller bearings. Someone pulled a shield off one side of each bearing. Maybe to grease it to fix the noise??

IMPORTANT NOTE: 6202-2RS-16 is the correct bearing today. The dash 16 gets you the correct 16mm ID. Otherwise, a modern 6202 has a 15mm ID.

Steve F, thanks for the tip. I'll try to paint my dials while I wait for the bearings.

I posted a pic of another spindle I had in with the tooling earlier. I think I found it's purpose.

Since I'm on hold waiting for bearings I tried a few slightly different methods to paint my dials. Came out ok. A little easier for me to see so worth the effort.

The indicator for the nod angle cleaned up pretty good but there's really no line as a reference point. Maybe it's supposed to line up on the edge of the slot. I guess I can make my own mark. I think it's just to get close and then tram it in.

Thanks Steve. I need to get some more tools on board so I can set it up when it's done. I need to get an indicator to tram it. Well for other things too. I have a few I use to set up differentials and such but they read in .001 increments. I was thinking of just using one VS the bar that holds two??

Should I start a new thread on tooling and setup advice? End this thread when I finish assembly?
