G0695 Mill Vibration Issues! I Need Guidance....

I got them to send all bearings, the pulley and splined sleeve for the headstock. Virtually everything that rotates except the spindle. Parts are back ordered for 60 days. Customer service is still good in my book, just kinda sour about the machine q.c. Anybody have an idea where to get a 60mm spanner socket? I'll be needing one to tear down my machine. Thanks for all of the help.

Apparently on eBay:

Ebay search for 60mm socket

With the motor on the mill, but no belt installed, do you get any vibration with the motor at full speed?

Have you tried removing the belt, putting a dial test indicator on the edge of the pulley groove (where the v-belt runs), and turning the spindle by hand to see if the pulley is wobbling?

A 60mm socket won't work. I need a 4 pin 60mm spanner.

The motor without belt connected gets a bit of a buzz but not like the one I replaced (which was missing parts). I do not have a dial test indicator yet. As I said, my focus is on the welding side of things and this machine was the first purchase toward the machining side. I have a load of goodies coming from LMS this week. I will live with the rattle until the parts get to me.
 
I would also try to adjust the belt tension to see how that effects the vibration. I recall in your previous video on your machine the belt was fluttering quite a bit. It could be a balance problem on the spindle pulley, or it wobbles, should be able to see the latter when it is running. After the belt, I would replace the pulley before tearing the head apart.

ahh, missed that you were looking for a pin wrench. Do you need the kind that has the pins on the face, or a hook on the end of the wrench?

Neither is cheap, although Enco has a 20% off sale with free shipping special right now which would help (codes: APRDS and APRFF):

I need the socket style. The spanner nut sits too deep in the pulley for the wrench style.

I tried gorilla tight to loose and all points between on belt tension. Zero difference. I even tried an American made Gates BX (cogged) belt. I think your advice is solid. I plan on changing the pulley first, then the splined drive sleeve, and so on. That will allow me to see exactly which part is to blame. Grizzly told me 60 days back order. Four days later, all parts shipped......not too shabby. Grizzly CS has done well. Can't complain. Just ready to put a done stamp on this and move on. Thanks for hangin' in here with me guys!

My bet is some tech went and stripped it off a machine in the warehouse, and they will install the parts on that machine when they arrive on the slow boat from china. Heard that story before. Good news for you!

Supervisor probably decided making you wait 60 days would put a crimp in their plans to sell you a lathe next month....

I imagine thats exactly what they did. I'm pleased with that. And I did mention that I will be in the market for a lathe (which is true) and I'm not feeling so confidnt in Grizzly (also true).
