Craftsman 113241730 9" direct-drive table saw Parts

No. Table saw arbor nuts are not all the same size because arbor shaft diameter, thread size, and thread direction vary by saw design. On the Craftsman 113241730 9" direct-drive table saw, you need to match the nut to the exact arbor threads and flange setup, not just the blade bore.

What actually has to match

Arbor nuts are defined by more than “table saw” or “9-inch”:

• Arbor shaft diameter (common sizes include 5/8 inch on many saws)
• Thread pitch (fine vs coarse threads)
• Thread direction (right-hand vs left-hand threads)
• Nut style (hex nut, flange nut, or a nut used with a separate washer)
• Arbor length and flange thickness (affects how much thread engagement you get)

Quick reality check: blade bore vs arbor nut

Many blades share common bore sizes, but that does not make arbor nuts universal.

Item	What’s often “standard”	What varies a lot
Saw blade bore (center hole)	Commonly 5/8 inch on many table saw blades	Some blades use 1 inch bore or reducer bushings
Arbor nut	No true universal standard	Diameter, pitch, direction, thickness, flange style

How we recommend confirming the correct arbor nut

Use these steps to avoid cross-threading or a loose blade:

• Confirm the model number is 113241730 on the saw’s ID tag
• Remove the blade and inspect the arbor threads for damage or flattening
• Use a thread gauge (or compare to known nuts) to identify thread pitch
• Note whether the nut tightens clockwise or counterclockwise
• When ordering, search by model number on Sears PartsDirect so the nut matches the correct Craftsman arbor assembly

Why it matters

The arbor nut is a primary blade-retention fastener. If the nut is the wrong thread or style, it can loosen during cutting, damage the arbor threads, or prevent the blade from clamping flat against the arbor flange.

A Craftsman 113241730 9" direct-drive table saw typically sells in the used market because it is an older model; most working units land around $150 to $400, with price driven mainly by condition and whether key safety parts are included.

What affects the price most

• Overall condition: smooth height/tilt adjustment, flat table, no excessive arbor play
• Motor health: starts quickly, no burning smell, no heavy sparking at the brushes
• Fence and miter gauge: complete, straight, and locks securely
• Safety equipment: blade guard, splitter/riving-style parts, anti-kickback pawls (if included)
• Included extras: stand, dado insert, extra blades, push stick, original hardware

Quick pricing guide (common scenarios)

Condition / package	What you usually see	Typical price range
Parts-only / not running	Missing fence or motor issues	$25 to $125
Running, basic setup	Usable but worn, limited accessories	$150 to $250
Clean, tuned, complete	Fence locks well, guard included	$250 to $400

How we recommend valuing your exact saw

1. Confirm the model tag reads 113241730 (not a close variant).
2. Check the top for rust pitting and verify the blade raises, lowers, and tilts smoothly.
3. Make a short test cut in hardwood; listen for bogging or beltless direct-drive chatter.
4. Price higher only if the fence is solid and the saw includes the guard and throat plate.

Why it matters

Table saw value is tied to accuracy and safety. A complete Craftsman 113241730 with a dependable fence and intact guarding is worth significantly more than a similar saw missing those parts because replacements can be hard to match correctly.

If you are getting rid of an old Craftsman 113241730 9-inch direct-drive table saw, the best options are to sell or donate it if it still runs, or recycle it through a local scrap-metal or e-waste program if it does not. Before transport, remove the blade and secure the cord so it cannot start accidentally.

Best disposal options (from most to least value)

• Sell or give away: List it locally as “working” or “for parts” and include the model number 113241730.
• Donate: Many community shops, schools, and reuse programs accept working power tools.
• Recycle as scrap metal: Most table saws contain a lot of steel and aluminum that scrap yards accept.
• E-waste drop-off: If the motor, switch, or wiring is damaged, an e-waste facility can route it properly.
• Junk removal: Use this when you cannot transport it safely.

Safety steps before you move or dispose of it

• Unplug the saw and remove the blade.
• Lower the blade fully and lock any height or bevel adjustments.
• Remove loose accessories (miter gauge, rip fence, throat plate) and bag the hardware.
• Tape or tie the power cord to the cabinet so it does not snag.
• If the cord insulation is cracked or wires are exposed, avoid handling the damaged area; wear gloves.

Blade handling: what to do with it

Saw blades are sharp and should be handled separately from the saw.

Item	What to do	Why
Steel blade	Wrap in cardboard and tape closed; recycle with scrap metal if accepted	Prevents cuts and makes recycling easier
Carbide-tipped blade	Wrap and label “sharp”; many scrap yards still accept it	Carbide tips can change how it is processed
Rusted or damaged blade	Wrap and dispose per local rules	Reduces injury risk during handling

Why it matters

A table saw is heavy, has sharp edges, and includes electrical components. Disposing of it through reuse or recycling keeps metal out of landfills and reduces the chance of injuries during curbside pickup.

Yes; you can use an 8-inch blade on a 10-inch table saw (including many Craftsman saws like model 113241730) if the blade’s arbor hole matches the saw’s arbor and the blade RPM rating meets or exceeds the saw’s no-load speed. You will lose cutting depth.

What changes when you switch to an 8-inch blade

An 8-inch blade is smaller, so the saw behaves a little differently:

• Maximum cut depth decreases by about 1 inch compared with a 10-inch blade
• The blade may sit lower relative to the guard, splitter, or riving knife; alignment must be checked
• The throat plate opening may not support the smaller blade well for narrow offcuts
• Cut quality can change depending on tooth count and grind (rip vs crosscut vs combination)

Compatibility checklist (do these before you install)

Use this quick check to avoid vibration, binding, or unsafe setups:

• Arbor hole size matches your saw (many 10-inch blades are 5/8 inch arbor)
• Blade RPM rating is at least the saw’s no-load RPM
• Blade clears the throat plate at full height and at bevel angles
• Guard, splitter, or riving knife can be installed and aligned with the smaller blade
• Blade kerf is compatible with the splitter/riving knife thickness (to reduce kickback risk)

8-inch vs 10-inch blade: practical differences

Item	8-inch blade on a 10-inch saw	10-inch blade on a 10-inch saw
Max cut depth	Lower	Higher
Typical use	Thin stock, specialty cuts	General-purpose cutting
Safety setup	May require extra checks	Usually straightforward

Why it matters

Blade diameter affects cut capacity and how well the safety hardware lines up. Confirming arbor fit, RPM rating, and splitter or riving-knife alignment helps prevent binding and kickback.
