This is a new old stock Ammco factory 9108235 lead screw assembly (short version - 14 1/4") with clutch manufactured in 2001 for older 3000 and 4000 brake lathes. It's never been used and has been sitting on a shelf in my garage for 25 years so there is some light surface rust present on the threads which should be cleaned off prior to installation. It is also recommended to replace the brass lead screw nut when installing the new lead screw assembly. For the drum feed, you'll need 904670. For the rotor feed, you'll need either 910868 (old style strictly for older lathes) or 928529 (new style which can be used on older and newer lathes). I haven't found any of those yet on my shelves. Please check out the other Ammco and Coats service parts and accessories I have listed.
