Thanks. I think it would be helpful to see my mistakes or missteps l, as well as, any fixes and corrections. I should have measured and verified the belt first.Thanks for describing your process, I’m enjoying reading and have a 5913.
A while back there was a Clausing dealer who kept giving the wrong part number for the variable belt for some reason. They were giving the belt number for a Clausing drill press and it was too narrow. The drill press belt is probably what was put on your lathe. I think they were quoting the belt number from memory and just got it confused, but the issue has cropped up several times.The spacers took up the flop and raised the lower held rpm to 450-500rpm. However at the top compressed end the sheave stopped closing at 1500-1600rpm. I took a measurement on the belt width and confirmed the width is not correct. .9920" when it should be 1.19". That will do it.
It doesn't look worn so im assuming the wrong belt was used to replace the original. I'm seeing 1930v400 as original spec and a few 1922v400 as a better angle for the sheave. Any ideas or experience between the two?? Crappy thing is both appear to have been replaced not long ago, but for
peace of mind and convenience, going to have to replace both. I will probably hold off on that for a bit until i get some of the other items checked off my list.
1930V400 - Lower V-Belt
630H150 - Upper Timing Belt
Unfortunately 1930v400 is stamped on the belt. As far as I've read, Clausing has been giving out that belt and part number for years.A while back there was a Clausing dealer who kept giving the wrong part number for the variable belt for some reason.

Any chance you'd share the .stl file for the slave cylinder cover? I need one and have a 3D printer at work (so I can't make them to sell!).
