Can't see how to remove blade guard on older craftsman 10" radial arm saw to change blades also right or left thread??

Penetrating oil may help, use AG-10 if you can get it. Tap the frozen part with a hammer, a rawhide one if possible, for 1 minute while attempting to wiggle the part. If you get it out, file the mating surfaces and coat with an anti-sieze compound such as Never-Seez before you reassemble it.

This started in 2000. f you have an older craftsman/sears radial arm saw, visit this website for either $100 or an awesome upgrade kit including tables, fence and a really nice and safe blade guard. Recall website: http://rasrecall.com/default.aspx

contact craftsman manufacturer spares to see if they are available
one washer will have a slot across the back and is the driving washer for the blade
the front washer will be flat and is the clamping washer
most manufacturers use generic products here so check for washers from other 10 " saws ( appliance repair shops , junk yard shops etc)

Normally Sears is pretty good with older part . But if they do not have any go to a saw repair shop and see what they can do for you

Try checking on sears . Consult your manual as well.

Don't forget that the bolt that holds the blade against the arbor (the motor hub connection point) is threaded COUNTER-CLOCKWISE. This is the opposite of nearly everything else we encounter. Be sure to use the two wrenches you got with the saw, and like the directions always say, "Unplug unit before servicing!"

Hi Tom, W/D here.
There are usually three different ways that blades are installed and/or removed. All require that the power be removed from the saw first (pull the plug, please).
1. The most common method involves a shaft lock, so look for this first. It will appear as a button on the motor, near the blade. When you depress the button, you'll need to rotate the shaft/blade by hand until the lock sets in place in the shaft. Then, while still holding the shaft lock button down, use a wrench to loosen the blade. (Look at the threads to make sure that you are turning in the right direction, as this may be reverse threaded).
2. Less common is a shaft that has an allen socket in the end of it. Place the loosening wrench on the not, then place the allen wrench in the end of the shaft.
3. If all else fails, you can, VERY carefully, wedge the blade down into a piece of soft wood such as pine, then loosening the blade with a wrench. Make very sure that you keep all of your bodily parts out of the line of fire when using this method, as the blade can turn suddenly, and you don't want to have anything caught up and cut by the blade.
Hope this helps, Best regards, --W/D--

Place a finger nail in the thread near the end ot the shaft. If when rotated CW it comes off the shaft it is a left hand thread. My 10" Craftsman radial saw has a left hand thread on the blade shaft.

If you have more questions or need additional help please reply below and I will get back to you. HTH & Good Luck.

Thank You for using FixYa.

Removing the Blade
1. Unplug the saw.
2. Raise the arm to the upper position and raise the lower guard as far as possible.
3. Loosen, but do not remove guard bracket screw until the bracket can be raised far
enough to access the blade screw. Lower guard will remain raised due to the position
of the guard bracket screw.
4. Depress the spindle lock button (Fig. 3) while carefully rotating the saw blade by hand
until the lock engages
5. Keeping the button depressed, use the other hand and
the wrench provided to loosen the blade screw. (Turn
clockwise, left-hand threads.)
6. Remove the blade screw, outer blade clamp, and
blade. The inner blade clamp may be left on the
spindle.
Installing a Blade
1. Unplug the saw.
2. With the arm raised, the lower guard held open and the
guard bracket, place the blade on the spindle against
the inner blade clamp with the teeth at the bottom of
the blade pointing toward the back of the saw.
3. Assemble the outer blade clamp onto the spindle.
4. Install the blade screw and, engaging the spindle lock,
tighten the screw firmly with wrench provided. (Turn
counterclockwise, left-hand threads.)
5. Return the guard bracket to its original position and
firmly tighten the guard bracket screw to hold bracket
in place.
WARNING:
• The guard bracket must be returned
to its original position and the
screw tightened before activating
the saw.
• Failure to do so may allow the guard
to contact the spinning saw blade
resulting in damage to the saw and
severe personal injury
