Hi all.
I'm a little sick to my stomach writing this. I just got my 1340GT a couple of weeks ago and have really been enjoying it. This afternoon I was parting off some aluminum (with lots of oil) close to the chuck, when the tool stuck and ripped the piece right out of the jaws, which cause the parting tool to kick sideways into the chuck and quickly stop the works. The idea that I may have severely damaged my brand new toy felt like a kick in the...well, you know.
I hit the e-stop as quick as I could, but by that time the damage is pretty much done. I was running extremely slow (maybe 60-70 RPM), so I think I managed to avoid any major damage. I disassembled the work, spun the chuck by hand, then jogged it for a few rounds. When I started the motor back up, there was a noticeable tick. I stopped again, pulled the cover off the gearbox, and slowly rotated everything by hand to take a look at the gear teeth. Nothing looks perceptibly damaged, and to be honest the tick may have been there before but I had just ignored it. There were no chipped or bent teeth (that I could tell). The spline shafts don't appear damaged. The shift palls look good. Everything moves smoothly. The tick only happens in low gear. It doesn't matter if it is L1, L2, or L3, the sound is the same. The tick doesn't exist at all in high gear. That lead me to believe I may have damaged the final low input gear that drives the main spindle. When I jog the machine with the cover off, I can just barely hear it, and it seems to correspond to the rotation of the low input gear.
What would you guys do? I'm tempted to just run it for a while without a load and let the gears wear back together. It's not a grinding sound, just a light tick. I could try to disassemble the gear train and do a deep inspection, but that proposition scares me a little. I would expect a person needs a pretty decent machine shop to tackle a job like that. Thoughts?
