It needs to be fixed. i can't find the spanner nut to remove the taper bushing. I've looked all over the internet. M24 1.5 pitch

Call Hartwig in St. Louis. They will either have it or know where to get it. Those machines are rocks; we bought ours used in 1992 and have run it hard since. Not the fastest machine in the shop, but the most trouble-free.

I assume this must hold the pulley on? Why can't you just smack it to break the taper. I have never had much luck with just pressure to break a taper or compression bushing. You need pressure and a good steel on steel smack.


If this is the X axis and I assume the LB is a slant bed make sure you have a 4X4 blocking it up. Saw a guy use a C clamp on the way once ... didn't work.
