Close inspection of the parts diagram (anyone want to give me an HLVH-H so I
know for sure, I missed out on two before I got the HLV), shows that the inner
races are separated by a spacer and clamped between the mandrel nose and the
pulley. The outer races are separated by a spacer closely fitted and keyed to
the headstock casting (can be assumed to be thermally part of it). The front
outer race is restrained on both sides, but the rear outer race is only
restrained on the "inside"


The spacer isnt keyed to anything. Its simply on the spindle tube.
Almost an interference fit.


I didn't mean the spacer on the spindle, I meant the one in the headstock
casting. The parts diagram seems to imply that there's a dowel going through
the top of the headstock casting to hold it in place. Although the book
doesn't show a part number for either part...


Ayup..there is indeed a dowel holding the "spindle cavity" Stuff in the
rough headstock. As its not removable..the thing is simply part of the
manufacturing process and is not intended for removal. Though I did see
one that was partially out once.

They figure the drunk on the forklift hit it about 15 mph..perfect shot
on the end of the collet closer with one fork of a 12,000 lb forklift.

Moved the machine into the next room..right through a wall and the mens
bathroom.....VBG

The Stuff was sticking out about 1.5"

So it was put in pretty damned good.

They pulled the headstock and sent it back to Hardinge. It was returned
about 3 weeks later, all back in good running condition. Didnt even have
to replace the spindle...but it did need a new collet closer.

Good machines indeed
