Craftsman 31517491 router Parts

Yes. Craftsman makes corded routers, and your Craftsman model 31517491 is a corded electric router (it uses a power cord rather than a battery) designed for steady, full-time power during routing and edge-forming work.

A corded router plugs into a standard outlet and typically has a fixed power cord coming out of the motor housing.

• Look for a permanently attached cord at the rear of the router
• Check the tool label for amps (A) rather than battery voltage
• Confirm there is no battery slide or battery release latch
• Verify the switch is a standard on/off trigger or rocker (not an electronic battery interface)

Corded and cordless routers can do similar woodworking tasks, but they behave differently in day-to-day use.

If you are choosing bits, extension cords, or planning a repair, knowing you have a corded Craftsman router helps you match the right electrical setup (outlet, cord gauge, and switch behavior) and avoid power drop that can cause burning or chatter.

If your corded router will not power on, these guides help you troubleshoot safely with basic electrical testing.

The model number for your Craftsman router is printed on the tool’s identification label; on model 31517491, it’s typically on the motor housing or base near the handles. Match the full number exactly so we can help you find the correct diagrams and replacement parts.

Check these common label locations:

• Side of the motor housing (near the on/off switch)
• On the router base (outside edge or underside)
• Near the cord entry point or strain relief
• On the nameplate by the handles
• Inside the base area after removing the motor from the base (if your design allows)

Most Craftsman power tools list several identifiers. Use the model number for parts lookup.

Getting the exact model number matters because routers can have multiple versions that look similar.

• Write the model number exactly as shown (include all digits)
• If the label is worn, take a clear photo and zoom in
• Compare the model number on the label to the one you search
• If you see a second number (like a type or revision), keep it noted for reference

Craftsman router parts like brushes, switches, collets, and bases can vary by production run; using the correct model number ensures the parts list and diagrams match your specific tool.

A Craftsman router like model 31517491 typically lasts 10 to 15 years with normal DIY use and basic maintenance. Heavy, daily use shortens lifespan; keeping the motor cool, the collet clean, and the brushes in good shape extends service life.

These factors have the biggest impact on how long a router motor and bearings last:

• Duty cycle: long continuous cuts build heat and wear
• Dust control: fine wood dust accelerates switch and bearing wear
• Brush wear (if your router uses carbon brushes): worn brushes can damage the commutator
• Bit sharpness: dull bits overload the motor
• Collet condition: dirty or worn collets cause vibration and runout

Use this checklist to decide whether maintenance or repair makes sense:

• Burning smell, excessive sparking, or power drop under load
• Loud bearing noise (growl or squeal) that changes with speed
• Speed surging or intermittent power (often switch, cord, or brush related)
• Excessive vibration even with a known-straight bit

Routers fail most often from heat and dust; simple upkeep prevents motor damage and keeps cuts accurate and safe.

If you’re troubleshooting power loss or intermittent operation, follow the steps in [how to tell if a fuse is blown] to rule out basic electrical issues in your shop setup before digging into the tool.
