Hello ,
I have bought a Hardinge HLV-H "donor" lathe. The apron/carriage seems like it hardly saw any use, the spindles have very little play and the scrape signs are clearly visible. The headstock has bronze bearings with some kind of oil injection, it does not seem original hardinge, I will post some pics later.
However I decided to exchange the carriage with the one I have on my HLV-H.
After I did that and run some tests I noticed the crossfeed clutch was a bit 'sticky' it kept rotating a short period after I moved the lever down. I removed the clutch cap to re-adjust the nut but it did not help so I decided to unbolt the clutch assembly from the apron.
I noticed one of the four bolts, on the lower left side, was longer but I did not pay attention to that.
After inspecting i wanted to place back the clutch assembly but with he lower left bolt I did not find any thread anymore.
It seems there was something in the apron with thread which dissapeared?!
On my old carriage/apron i can remove and re-insert that longer bolt without a problem.
I hope somebody can clearify why that bolt is longer and/or whats it holding inside the apron.
I would like to avoid opening the apron but perhaps I have no choice.
Thanks for your help,
Melle
