Yes.
Saw is a "Kung FU Machinerty" Special.
I bought one for $50 in the mid '80s to throw in back of car for use
at the boat yard.
If you get 2 years, consider yourself lucky.

Sounds as if the proper replacement procedure would be, to paraphrase an
old musical-instrument repairperson acquaintance of mine:
1. Remove sawblade.
2. Slide new saw under sawblade.

Made With Pears: Pretty good chance that pears will be detectable in
the product.
Contains Pears: One pear seed per multiple tons of product.

My mid size (but not old monster, such as one sees in lumber yrads!)
bench saw has a separate one HP AC induction motor hanging out the
back using the weight of the motor to tension the drive belt. The step
up ratio, is, I think, about 2.5 to 1
Motor has thermal reset; some sort of starting contacts/winding AFIK;
no capacitor. It is connected in 230 volt mode. Was fortunate to
eventually find a double pole switch which have mounted on saw base.
Fortunately never had to have that motor apart.
But just curious? Do some of those all-in-one motorized bench saws
have a brush motor (direct drive) buried under the saw deck. I guess
in that case the saw blade is mounted directly on the motor arbor?

Yes, the low end saws like the Craftsman for $129 are like that. The have a
lot of limitations, but for many, they get the job done cheaply.

I have one of them sears specials here, that some one gave us, had to
replace a cap. on it to get it to run, but pay attention to setting the
fence parallel to the blade, and it makes pretty good cutsm been doing some
remodeling work here, its not as good as my other one at the shop at my dads
house, but it beats having to run back and forth, and it can be moved pretty
easy, since it does not have a cast iron top, no I know its not a $1500
cabinet saw, but for remodeling work, its pretty good, would have love one
of them fold up and roll away saws.
