Hi all,

I just picked up a Powermatic 63 on craigslist that needs a little work. The arbor is sticky when spinning it by hand—it by no means spins easily. Does anyone know where to source parts or if PM 64 & PM64A parts will work in a 63?

Thanks,

W

I also bought a Powermatic 63 from a CL seller, for $160 with a cracked trunion and bas arbor bearings. I welded the trunion with a nickel welding rod and found the bearings through web searches.

The bearings are available from http://www.vxb.com/ the model number is 6203Z they’re only a couple bucks each.

Powermatic.com has no support for the model 63, the Grizzly G1022 is essentialy the same and uses very similiar part numbers. You can download a very detailed owner’s manual with good alignment instructions.

It took me about an hour to replace the bearings, using a pickle to separate the arbor from the arbor housing. I used a gear puller to remove the blade side bearing and pounded the other out of the arbor housing with a thick dowel. When installing the new bearing DO NOT apply force to the outer bearing ring, use a socket or other sleeve to press the bearings in.

I checked the blade to miter channel distance and found about 0.0025” difference from front to back of the blade, the Vega ripfence is out by a similiar amount. I’m not going to mess with it.

Good luck.

Oops, I meant to say “pickle fork” to separate the arbor. A device for use in auto ball joints/tie rod ends, about $10 from NAPA autoparts.

Bearings are usually quite universal. Biggest difference being in open bearings, sealed bearings and sealed and shealded bearings. You should be able to read the numbers on the old bearings and go to a bearing supply house and get the same thing.

I agree with Maynard. I just replaced bearings in a 60 year old Unisaw. Picked them up at a local bearing supply

Never order bearings from a tool manufacturer. They just get them from some bearing manufacturer and mark them up to you—-a lot!
