I have a Jet JWTS-10J right hand tilt contractors saw and it appears the arbor bearings are wearing out and will soon need replacement. Does anyone have experience replacing these bearings? If so can you tell me how difficult it is and do I have to remove the top to get the arbor out of the saw? Thanks for any help you can give me.

Not that particular saw, Stubby, but many including Rockwell Contractor Saws.

Turning it upside down is step one. You’ll see then how best to remove the trunnion assembly if you have to.

Pulley removal is followed by sliding the arbor itself, along with its bearings, out of the cast housing.
(If you don’t have a small puller for the pulley, you can get one from HF, etc. Don’t try anything damaging; get the tool.)

That assembly will travel with you to the bearing supply place where they usually have the facility to remove and replace the bearings.

Then replacing the top: Takes patience to get everything right. You’ll want the blade vertical to be parallel to the miter gauge slots. Trial and error.

There are lots of good things to be learned in doing this, and I hope you tackle it.

Kindly,

Lee

Thanks for your help Lee. It looks like this is going to turn into a project because I have table extensions on both ends of the saw, a cast iron router extension on left side and a 52” Incra fence on the right side with table extensions and dust collection coming in from top and bottom so it will be challenging to turn it over. Bottom line I am retired and have more time than money to buy a new saw right now.

Sounds like a chore, but it seems to me coming in from the back or crawling underneath is worse.

Before you set it back up, look for a good reference work on how to do that. FWW had one many years ago, and maybe somebody catching this thread will have a reference. The reward is a really sweet running, easily adjusted saw. And if you don’t already have a segmented belt on it, this would be a good time to add one.

Kindly,

Lee
