3520B berrings
Jul 3rd, 2017 at 8:38pm
 
At certain speeds I am getting a rattle coming from the head stock. I put a meter on the shaft and am getting .004 swing and at some speeds more than that. Can't determine where exactly the rattle comes from as  in front or back. My question is about changing out the bearings. Has anyone had to do this and an idea what it takes.
Thanks for reading,
Lee

Changing the bearings is not really hard to do. Bearings come in standard sizes and styles. Your bearings will have a code stamped on them you can use to get replacements. I got mine from" VXB. Com" they are not very expensive. There is a clip on U-Tube that shows how to do it on your Powermatic. Took me about a hour to do.

The rattle can be several things, including loose set screws on the pulley and the spindle lock. I had to get the bearings on my 3520A replaced. They were creaking rather than rattling. I got the bearings locally and a new belt, and had a local tool repair place fix it for less than the parts would have cost from PM. I took the headstock to the repair shop. Good thing since I turn really wet wood, and they had kind of rusted in place...

Here is a tutorial for replacing the bearings on a Jet 1642, which is very similar to your Powermatic. It's actually a two part clip.

Before disassembling my PM 4224 I turned some drive blocks if you will out of poplar to help install the new bearings.  They made installation a breeze, not sure how it would have turned out if I didn't have them.
