Pully Sizes? Craftsman Table Saw
 

Hi,

I have just bought a model 113.29991 ten-inch Sears Craftsman table saw. It
is powered by a 3/4 HP sears motor rated at 1750 rpm (5/8 inch shaft). I
plan to replace the pullies but I'd like to be sure of the proper sizes. Can
anybody give me some guidance on this? Much thanks.

Check your blade suggested rpm, or, as is usually the case, make it so the
blade rotates at about 4200 rpm. Arbor belt a touch smaller than half of
the motor.

They make a kit that has the pulley and a lenght of link belt that fits
the craftsman saw. One of the best things I ever did for mine. Cut
vibration a substantal amount and increased power. I know Woodcraft
sells the upgrade, I am sure others must as well. As I recall the price
was somewhere in the high 50's US $. If you really need the size let me
know and I will measure it.

Careful! That kit's for a 3450 motor. If he has a 1725, it'll be a while
before he gets through a four foot board.

Yea, your right, sorry. Is it possible they make one for the 1725? It
would have the same issues with cast pulleys and belt slipping, wouldn't
it?

No, standard motors have been 3450 for so long - 40 years I can vouch for,
that it wouldn't be worth it.

I don't believe machined versus cast make a hell of a lot of difference when
you're talking small diameters and a self-hung motor. The differences would
have to be so gross as to be visible.

I rebuilt SWMBO's father's Craftsman tablesaw a few years ago. I don't
know the number, but it was the cast iron top contractor saw built by
Emerson Electric.

It had a 3450 rpm motor and two 2-1/2" white metal pulleys on the motor
and arbor shafts. These had each worn their bores oval and you could
see them wobble.

I replaced them with machined steel pulleys and linkbelt. The arbor
bearings were also sloppy so I replaced them, too. Lined everything up
and the saw vibration was much reduced. (Just vibration from the motor
now.)

Double check your motor rpm. If it is 1750, then double the motor
pulley size to 5" so the blade turns fast enough. Double check the
belt clearance with everthing with the blade up and down to make sure
the larger motor pulley doesn't drive the belt into anything. If there
is clearance trouble you can't adjust for, that'll force you to a
smaller motor pulley.

If you don't have a manual, check the Sears website. Failing that, go
to the Ridgid tools website and download one of their tablesaw manuals.
Emerson Electric now makes the Ridgid saws. The alignment and belt
tensioning instructions are helpful.

Good luck,

Tim

mine is a 1 HP and 3450
