I bought a 113 series Craftsman table saw off FB marketplace/craigslist a few months ago. It worked, but it was pretty rusty, so I wanted to refurbish it. It's also way too heavy for me to lift onto the workbench, so I'd have to disassemble it anyways. I took lots of pictures during this process, and put fasteners in labeled bags so I'd be able to put it back together.

before disassembly |
|
So much rust |
|
First step: remove the belt |
|
Then removed the motor + motor mount. The two pins slide out, so the whole assembly comes off. |
|
Removed the blade next. No arbor flats, so I used a block of wood to keep the blade from spinning. |
|
Took the fence bars and wings off |
|
Flipped it over onto another furniture dolly |
|
Had to disconnect the bevel screw before I could slide the box off towards the rear. |
|
Trunion assembly exposed. So much rust |
|
Made some good progress prying the arbor pulley off until I broke it. Sigh... |
|
Used the handwheel to screw the lift screw out after removing the retaining rings. |
|
Current state of disassembly. |
Obviously a lot left to do on this one.
- Buy a 3-jaw external puller and pull pulleys off
- Buy an internal slide hammer puller, or make something equivalent, to pull the arbor bearings and motor bearings out. The bearings are old, and while they aren't in horrible shape, I might as well replace them while everything is apart.
- Buy replacement pulleys and key stock. I'm going to buy some machined steel pulleys from in-line industries; they should be better balanced and lost longer than cast iron/zinc ones. I already have a link belt, which are supposedly the best.
- Buy replacement bearings. I'll probably buy some mid-high quality ones because replacing them is such a pain. I have a hydraulic press, so installing them shouldn't be too bad.
- Buy replacement fasteners. Most of the old ones are too rusty to save, though I'll attempt it.
- Finish disassembly
- Make sure to mark the motor casing and ends so that I reassemble it in same orientation.
- Clean dust, paint, grime, etc. off all of the parts. Scotchbrite and WD-40.
- I may need to flatten the arbor face if it's rough/not flat. Luckily, I have a mini-lathe, which will make that easy.
- Use Evaporust on everything to remove the rust.
- Spray CRC corrosion inhibitor on almost everything to prevent it from re-rusting. A lot of people use "T9 Boeshield", but I already have the CRC from a project a long time ago, so I'll just use that.
- The paint on the motor and box is in decent shape. I'll need to derust and touch up a few spots, but I shouldn't need to do any repainting.
- The side of the box with the bevel screw-wheel mount bows out due to the force of the bevel screw, so I'm going to reinforce it with some 1/2" plywood.
- Reassemble everything.
- The manual lists things that need oiling, so I'll do that while I'm reassembling it. Some people suggest using paraffin wax or dry lube instead because they tend to collect less dust.
- The wings are slightly bowed, but this video shows a good process for getting them level with the center top.
- If there's not enough clearance in the trunion mount bolt-holes to get the blade aligned, I'll buy the in-line industries PALS system, which supposedly makes alignment easy. This video is pretty good for regular alignment.
- Apply johnsons paste wax to the top. The CRC coating is a little gummy (the T9 stuff is too), and the paste wax will make the top slippery, while providing additional protection.
- 3D print insert plates, including a zero clearance one with holes for a splitter behind the blade.
I'm planning to replace the fence eventually. I'll do a big write up on that later, but the short of it is that I didn't find any table saw fences that I like or that were reasonably priced. So I'll leave you with this teaser:
Like some of my previous teasers, this may take a long time to come to fruition, if it ever does...
