Before all the replies about Craftsman junk, etc. let me say, this is an
older (1978 or so) craftsman table saw that has been just fine for me.
I need to replace the arbor bearings and have figured out how to get
everything loose but can't get the arbor out of the housing. The
problem seems to be a woodruff key on the end of the arbor that I can't
get to budge. I have tapped the end of it, used Smash, had a friend
try, etc. but nothing seems to move it.
Anyone had a similar problem? I really hate to buy a new saw when this
one just needs bearings. I read the article on Woodworker's Bench Notes
about replacing the bearing, etc. which was very helpful but there was
no woodruff key to deal with in that description.
As suggested penetrating oil and a propane torch should loosen the key,
try tapping down on one end, the key should basically rock up in the
keyway. If it is really ceased you may have to try a narrow chisel to
loosen it, tap the chisel under the end of the key and down into the
My Craftsman from the late 50's, early 60s
certainly has a key. But the first question is,
do you really need new bearings? have you tested
runout? If you have fine, but my saw, which my
father used a tremendous amount, still has the
original bearings and they exhibit no wear.
In any case you got the advice you need. Heat and
cold alternately can break almost anything loose.
The saw was making a scraping noise (like metal on metal) which kept
getting worse. I tried several different blades, etc. I replaced the
belt but it didn't stop the noise. I had a friend who works in a wood
and machine shop look at it and he thought it was the bearings for sure.
I'm still not totally convinced it's the bearings but took his word for
the source of the noise. May have been a big mistake on my part.
Thanks for all the responses.
