An engine hoist in a small shop is a necessity in my opinion. I have moved this machine 3 or 4 times along with lifting all the heavy sub components and it's still proven to be the best money I've spent in the shop thus far. It's also what makes doing all this solo even possible.
The teardown was pretty straight forward. I downloaded the Grizzly G0730 manual for a parts and assembly reference. The Grizzly model is identical to this mill. It's since been discontinued however but the G0731 is still available except comes with a factory x-axis power feed.

All the oil on the machine had turned into a varnish. Nothing slid but the sliding surfaces looked great. I used lots of penetrating oil to get things
to start moving.

Thick chunk of (old grease?) blocking off one of the knee oil feeds. I'm not even sure how this would have gotten in there but good to find.

The spindle was seized and the grease on top was clumpy. In fact all the grease in the machine is clumpy. While the upper bearing (visible in picture) was trash the spindle bearings did clean up beautifully. Had I put power to the machine right from the get go they would have been trashed as well. Along with the upper head bearings which also cleaned up great.
