Good job

Some last minute info in case other Acra 2S owners stumble here for info:

I posted the bearing info above, but you'll see that when you pull everything apart. I leaned heavily on

for the info -- the process is absolutely identical, with the exception that the lock washer was already pleasantly prebent. I also used Mobilgrease 28, based on a comment on Practical Machinist -- someoone had gotten advice from H&W on what they recommend.

Also, take everything I said with a grain of salt. I'm no pro.

Thanks for all the comments and suggestions, everyone!

The vids from H&W were the greatest help when I went through the rescue/cleanup of my new to me
Acra mill last fall, ( My new shop baby in the Bridgeport & clones section ).
Unfortunately I will be needing to replace either the motor bearings or the upper spindle bearings
soon as one or the other set has started to make noise when its cold in the shop.
Hoping it isn't both, but with my luck ...........

It's not unlikely to be the pulley bearings. Mine were worn enough to release the preload and were quite noisy. The motor bearings are probably fine.
