That is the largest diameter that will pass though the headstock on this lathe?

If you take the drawbar out, the max ID is the OD of the shank of a 5C collet.

Not familiar with the -434 is that a special version with a special collet, 16C perhaps? My HLV-H and HXL use the same spindle bearings so I guess it is possible that Hardinge built a couple of odd ball HLV-Hs. I know they built one with an extra long bed for threading lead screws.
If as Jim suggested this is a 5C designation, a smidgen under 1-1/4 would be the largest through the headstock with the key removed. And I would not remove my key for any use that I could think of. I know I have turned 1-1/8 without removing the key and using a 3 jaw chuck. Not sure what the upper limit is without removing the key is, maybe 1-3/16?
With a collet 27 mm or 1-1/16 .
