Finally got the oil in the spindle bearings changed today since it was warmer than the past week or so, up to 30 degrees F.
There was a comment in a post I read somewhere advising people to change oil in the gear boxes on Asian imports that I strongly support after today.
Even though I am the second owner of my Grizzly G9249 lathe I found black material in each bearing reservoir. The reservoirs are not very big and the "fill" tube discharges in the rear f the sight glass chamber ( which is also the drain port) so flushing by adding oil doesn't flush the bearing area. I used a long spout oil can to get flushing oil into the bearing chamber. Then I used a long 1/4" drill bit rotating it by hand in the drain channel to "pump" the flushing oil out and also drag out some particles of sand etc.
I also found sand particles in the rear of the quick change gear box. No doubt the previous owner/s did not do a thorough inspection and clean-up, and as stated in the blog I read the manufactures didn't do a good job of cleaning the casting sand.
I have turned 2 simple pins for an egine hoist and like the machine, with different types of controls it is taking some time to get used to.
