Hi All!

I put my Mark V/7 mounted planer on a pro planer bench with motor, and ordered the planer pulley upgrade from SS. The pulleys finally arrived today and got everything installed. I haven't run the planer in a while and it's an older one that I bought used a few years ago. Now my cutter head bearings sound dry; they growl - especially when the planer is spinning down at power off. I looked at the SS website and it lists those bearings as "N/A" for the mounted and the pro planer. Can anyone tell me what size those bearings are? I know I could probably get a number off of them, but I'd rather not tear down the planer until I have the new parts on hand. I don't want to lose parts or forget where something goes... Thanks!

Looking in my Pro Planer parts list it is #513388. I did a search on the website and it came up as http://www.shopsmith.com/ownersite/item ... tem=513388 Like you I don't wanna pull it it apart to check the size. Hopefully somebody else has that info.

I just got my replacment bearings for the cutting head on the planer, the size that I ordered that matched the dimentions of the ones that where on there is 6203.2RS. The dimentions are 17mm d (inner) x 40mm D (outer) x 12mm W.

Thanks, Skizzity! I've got a manual for both versions with the parts explosions, but it didn't occur to me to look there. I guess I figured I'd find it on the website or not - duh.... I also figured they had to be the same bearings as - for instance - the jointer or the headstock quill. I went back to tinker with the planer some more and now it's running quietly. I think the growling may have actually been the cutter head pulley set screw had come loose. The new pulleys did not come with keys, so I put the set screw on the flat of the shaft (like the power coupler drive hub). It backed off apparently, so I retightened and it seems to be staying now. I'll find a key somewhere tomorrow.

Thanks, Wolf!

Same as motor bearings/.(except rear Emerson IIRC)

Thanks, JPG. I got a new machine key today (they have them in the hardware section at the Blue Box FYI) and mounted the pulley "correctly". Honed the knives, waxed the table, "dialed in"the the rollers and she's race-ready now! Err, she would be if she had wheels; still waiting for SPT casters to ship from "Mom".

Do not run your planer under any circumstances with the upper pulley set screw set to the flat on the shaft. Trust me from experience, it will not stay tight. It will come loose and in short order. Since you have put your new pulley on with a 3/16" key and set the lock screw to the key and not the flat, you are good to go. When I got my planer, someone had lost the key and run the planer with the set screw set to the flat and ruined the pulley. I did what you did but a little differently. You can look at how by looking at the thread I posted "SS Planer".

Thanks for the tip, Don. When I tightened that top pulley the first time I ran it, I must not have had it lined up square on the flat which caused my growling. I swear it sounded like dry bearings and a tight belt. I adjusted the belt tension first which is when I discovered the loose pulley. I figured it wouldn't hurt to run it like that without "loading" it, but it stands to reason that if there's a key way - use a key.

Let's call a flat a flat and a keyway a keyway.

And yes one should not tighten a set screw onto a keyway without a key present.
