Craftsman 113176120 wet/dry vacuum Parts

For the Craftsman 113176120 wet/dry vacuum, the main parts you will see are the power and airflow parts (motor and fan area), filtration parts (filter and retainer hardware), and cleaning/handling parts (hose, wands, and tools). Your exact breakdown and diagrams are in the 113176120 owner's manual.

Common wet/dry vacuum parts (and what they do)

• Motor and power switch: creates suction and turns the vacuum on/off
• Tank (canister): holds debris and liquid pickup
• Lid/head assembly: houses the motor and seals to the tank
• Filter and filter retainer: traps dust before air exits the vacuum
• Hose: carries airflow and debris from the pickup point to the tank
• Wands and nozzles: extend reach and focus suction for different surfaces

Model-specific parts we list for Craftsman 113176120

These are examples of parts available for this model that fit into the “tools and filtration hardware” categories:

• Nut (white) 551006115 (filter retainer hardware)
• Wet/dry vacuum extension wand 551004117 (reach and handling)
• Wet/dry vacuum crevice tool 551012109 (tight spaces)

Part category	What you’ll notice when it fails	Typical fix
Filtration (filter/retainer)	Dust blowing out, reduced suction	Reseat filter, replace worn retainer hardware
Hose/wands/tools	Poor pickup at the nozzle, air leaks	Check for cracks, clogs, loose connections
Tank seal/lid fit	Whistling leak, weak suction	Clean sealing surfaces, confirm lid is seated evenly

Quick checks before ordering parts

• Unplug the vacuum; remove the lid and check for a clogged hose or wand.
• Confirm the filter is installed correctly and not packed with fine dust.
• Inspect the tank rim and lid seal area for debris that prevents a tight seal.
• Look for cracks in the hose, wand connections, or tool ends.
• If suction is weak, test with no hose attached to isolate a blockage.

Why it matters

Wet/dry vacuums rely on an airtight path from the tool to the tank and through the filter. A small air leak, clog, or mis-seated filter can reduce suction dramatically, even when the motor is running normally.

On a Craftsman wet/dry vacuum like model 113176120, the model number is printed on the rating label (data plate). We typically find that label on the upper tank or powerhead area, often near the handle, cord wrap, or where the motor housing meets the drum.

Where to look first (fast checks)

• Check the powerhead (motor housing) near the carry handle.
• Look around the cord wrap or cord entry point.
• Inspect the upper tank rim where the powerhead latches to the drum.
• Check the back side of the powerhead, near the switch.
• Look inside the rear wheel/handle area if your vac has a rear dolly.

What the label looks like

The model number is usually on a sticker or metal plate that includes:

• Model number (for this page: 113176120)
• Electrical rating (volts/amps)
• Serial number
• Safety marks and manufacturer info

If the label is missing or unreadable

If the sticker is worn off, you can still match parts by comparing your vacuum’s configuration (hose size, latch style, filter mount style, and accessory fit).

• Confirm your accessory connection style by checking a known fit part like the wet/dry vacuum extension wand 551004117.
• If your filter retainer hardware is missing, match it by shape and thread style; a common item on this model’s parts list is the nut (white) 551006115.
• Use the diagrams and identification notes in the owner's manual to verify the correct model and part locations.

Why it matters

Using the exact model number ensures the right Craftsman wet/dry vacuum parts fit correctly (filters, wands, and tools). A close model number can use different latches, filter retainers, or accessory diameters.

To remove the filter on your Craftsman wet/dry vacuum model 113176120, unplug the vacuum, remove the powerhead to access the filter area, loosen the center retainer/knob that holds the filter in place, then slide the filter straight off the filter cage.

Step-by-step: filter removal

• Unplug the vacuum and let the motor cool if it was just running.
• Release the latches and lift off the powerhead (motor lid).
• Locate the filter on the filter cage (usually centered under the powerhead).
• Turn the center retainer/knob counterclockwise until it comes off.
• Pull the filter straight off the cage; avoid forcing it at an angle.
• If it is stuck, gently tap or wiggle the filter to break loose dust, then pull again.

Quick checks before you reinstall

• Make sure the filter is seated evenly on the cage.
• Tighten the retainer snugly (hand-tight); do not overtighten.
• Empty the tank and check the lid gasket area for debris that can cause leaks.

Symptom after reinstall	Most common cause	What to do
Low suction	Filter clogged or installed crooked	Clean/replace filter; reseat filter squarely
Dust blowing out	Torn filter or missing/loose retainer	Replace filter; reinstall retainer correctly
Filter won’t slide on/off	Dust packed on cage	Clean cage and filter mounting area

Why it matters

A properly installed filter keeps fine dust out of the motor and maintains airflow. Running without a filter, or with a loose filter, causes poor pickup and can shorten motor life.

Parts and documentation

• Use the 113176120 manual for model-specific diagrams and the correct filter setup.
• If the center retainer/knob is missing or damaged, match the replacement by comparing your part to the diagrams and listings for your model; one commonly listed fastener for this vacuum is nut (white) 551006115.
• For additional parts and accessories for model 113176120, you can order from the parts list for this model or search by model number on Sears PartsDirect.
