Upgrading Sawstop Motor

I have a 1.75hp PCS Sawstop. I considered the 3hp version initially, but then balked at the extra cost and reasoned that 1.75hp would be more than enough. Fast forward two years and most of my woodworking involves thick 2” slabs…even with a sharp, thin kerf blade the motor really struggles. So, I called Sawstop to see if it was possible to upgrade the motor rather than have to buy a whole new saw. They were very helpful and explained that the 1.75 and 3hp PCS saws are the same, just with different motors and switch boxes. So yes, for $550 I could buy the motor and switch assembly and upgrade (which is basically the price difference between the two saws). I’d looked on the web to see if someone else had done the switch, but couldn’t find anything. Swapping motors was easy and took just over an hour; I documented the process in case anyone else does it.

Remove gas shock (top and bottom bolt):

Remove motor by removing mount bolts (19mm socket) and lift free from drive belt


Install new gas shock (easier to do with motor out)
Remove switch assembly and control box:

control box bolts:

Open switch assembly by removing seven screws

Then unclip white plug from old 120V control box and clip in plug from new control box. Reassemble and reinstall switch and control box onto saw

Reinstall new motor (may need someone to help hold the motor while you tighten the bolts, it’s heavy!) Make sure motor pulley lines up on drive belt. Drive belt tension: it should deflect less than 1/4” with finger pressure.

Feed motor power wire through opening in saw. Wire motor.

You’re now done, enjoy 3hp!

All-in-all, looks like it went pretty easily! Gotta love it when that happens!

Not bad! In the end you do end up paying a little extra ($120) but you end up with a spare 1.75hp motor. This is a great option for anyone who isn’t sure if they need the extra horsepower up front.

Thanks Rob; I wasn’t sure I needed 3hp when I bought the saw, but it was nice to be able to do such a simple upgrade when I needed it.
