I have a similar kit, from Harbor Freight. The o ring on my lathe came from it.

I've also used this same oring kit for my lathe as well. Works fine

Lathe is arrived, it need some love to shine again but it seem in good shape. For cleaning I'm considering to spray it with a motor cleaner and after with WD40 leaving it drying. Any other suggestions?
For second I will swap the motor with a silver can.

I'd avoid the WD40. It is not a lubricant, but it will displace your oil and/or grease. If people used it correctly, most would never own a can.

After I cleaned and lubricated my lathe, I just use air duster to clean it after use.

A toothbrush and WD40 will get all the grease and dirt off your parts as quickly and efficiently as anything. Then, wipe off and re-lubricate any bearings or moving parts. It's true that WD40 is not a lubricant, and most people have the mistaken idea that it is...but to get rid of moisture, dirt, oil & grease, it's fantastic. Got a grease or oil smear on your fabric car seat? Spray a bit of WD40 on it, agitate with a toothbrush, wipe and it's gone. Got stickers or leftover adhesive that you can't get rid of? Let it soak in some WD40 for a few minutes and it'll wipe away. I have a lot of uses for WD40 and never seem to have enough. I go through a lot of WD40 cleaning RC car parts.

I live on the coast and have fished my whole life, and WD40 is the bane of the fishing world. That stuff has been the downfall of so many reels that its ridiculous. My dad is a constant offender here.

I once got a smoking deal on a Shimano Calcutta Conquest on ebay because it was making some noise. As soon as I opened the box, I could smell the WD40. Luckily, they didn't continue using it. I had to thoroughly clean everything and properly oil grease it. It works perfect now.

We can agree on WD40 being mis-marketed and used as a lubricant, but for everything else--degreasing, removing water, adhesive removal, as a light penetrant or general cleaning--it's fantastic.

I suppose the caveat would be, if you use WD40, be sure to relubricate after use.

For the record, I would suppose a majority of us use water and soap to clean parts, and that's no better for corrosion than anything else. Thorough drying and relubrication is essential.

Let me be clear, I don't disagree that it can be useful. As with many things, the biggest problem is that people misuse it.

I also have a couple big cans, aerosol and liquid. Both are also several years old. Its just that anything that you would use it for, I have other products that I prefer.

Often I use WD40 as cleaner and protector. As cleaner removing it with a brush or with a towel and after the clean as protector leaving it drying. Never as lubricant.

In this case I intend to use motor cleaner do give to the lathe a deep clean without disassembling it (except for minor parts) and lubricate it after that WD40 will be dry.

I would avoid disassembling it to keep original allignement.
