Got an older FMC brake lathe like the JBC 601 or 701?

This little kit is what you need if the rotor feed is acting up.

It includes the 90077 nut and the 90071 screw, both brand new and made in the USA.

It’s from Online Auto Supply, so it’s a solid replacement part.
The packaging is simple, but the pieces are there and ready to install.
No UPC, but who cares when you’ve got the right part numbers.

If your lathe is skipping or not feeding right, this should get it back in action.

Straightforward fix.
