Default Is My Table Saw Arbor Shot? Bearings, Actually

I have a 70's era Craftsman contractors saw. 113.298031

When I move the blade by hand it feels "chunky". I took the belt off so that
I was just spinning the blade and arbor and it "hesitates" every 1/2" or so.
It doesn't spin freely even with the belt off. As I pull the blade along I
can feel a soft thump, thump, thump. No hard clunking, but it requires an
increase in pulling power to get it past those points.

See if this video works. I'm trying to move the blade with a constant amount
of pull and you can see the stop and go. (Yes, I'm turning it backwards, but
it does the same thing going forward.)

If the belt is off, the blade should not be doing that. I would say the
bearings are done.

Time for a new track saw? ;~)




I have a spare arbor (brand new) It has one bearing, the inside one near
the threads.

I guess I should order the outside bearing and tear the thing apart right?

From what I'm been reading, you're supposed take the entire arbor housing
out through the rear to get to the arbor bearing retainer screws. That
allows you to remove the outside bearing so you can slide the arbor
itself out.

Why not just cut a piece out of the sheet metal housing and do it all
from the side of the saw? As far as I can tell, that would give me direct
access to the 3 arbor bearing retainer screws. If I then covered the hole
with a piece of plywood (and sealed it up) I could hang all sorts of
accessories from the board. ;-) I'd also have easier access for future
maintenance/cleaning.


Can you remove the top and arbor trunion assembly?



Other than destroying the re-sell value of a saw that I paid $110 for in
the mid-80's, is there any reason not to go in through the side?
