I have an early model LZ330 without the selector for the input to the feed gearbox. (Yes, I change the gears manually ;-)
Reference the series of photos at the end of this page, Weiler LZ330 Lathe
Unfortuanately, I have not been able to obtain a parts list that includes the gear train details. Also unfortunately, the gearbox input shear pin was missing when I got the lathe, and I've replaced the part three times in the past year or so. Not knowing the original configuration, I've made up a 3mm dia. pins from mild steel (the input shaft is hard!) with a larger 6mm "head" on one end to engage one of the two slots in the input gear carrier sleeve. Thus I have a 3 mm diameter pin in single shear.
With the frequent failures, my most recent replacement was made from drill rod with a pressed on 6 mm driving "head". Still single shear.
I would like to know what the OEM configuration for this part is.
Perhaps the original design is a "soft" pin in double shear. i.e. two heads. That would require some sort of retainer I suppose.
Assistance welcome!
