I picked up a clean Jet 3HP cabinet saw for a great price. It all looks
fine and is only about 2 years old. I really do not believe it's been
However, I am able to grab onto the arbor flange and feel some play in the
bearings. Is this normal? On my older Delta contractor saw I could feel no
play. If I take hold and pull the arbor upwards I can feel a bit of play.
I really have no idea how much, but it's a few thousands I'm guessing. It
seems to be it should be nill.
Doesn't sound right. The fit for the bearings should be press onto
the arbor shaft and slip into the arbor bracket, In neither case
should there be any significant play. If the the arbor bracket bore
was machined too large you could have play. Or if the bearing are
internally worn in which case, replace.
Are you sure it is not just the whole arbor assembly moving? They
will, even if the lock knob is set.
How about the acid test? Can it be aligned and when so, does it cut w/o
leaving chatter marks? Does it run w/o obvious bearing noise from
either worn or dry bearings?
If so, no problem. If no, _then_ is time to worry. After all, the
point is to make sawdust, not play machinist... :)
Well, again, theory is good but if the practice shows no significant
problem, then what's the problem?
It's your choice, obviously, but I'd certainly hook the puppy up and
start working and then decide if needed something done rather than look
for something else to do first.
If, of course, you power it up and it squeals like a banshee, then
that's a necessary fix.
