Overview

These aftermarket carbon brushes provide reliable motor contact for power tools that depend on brushed motors. Carbon brushes are wear items that gradually shorten with use; once they reach their minimum length, the motor loses power or stops running entirely. Replacing them promptly prevents armature damage and keeps the tool performing at full output.

Key specifications

  • Aftermarket carbon brush replacement
  • Manufactured to OEM dimensions
  • Pre-formed contact surface for faster break-in
  • Spring-loaded design for consistent pressure

Compatibility

These brushes are designed for various manufacturers power tools as listed in the compatibility section above. Verify your tool’s model number and brush part number before purchasing to ensure correct dimensions and lead configuration.

Installation notes

Unplug the tool or remove the battery before replacing carbon brushes. Most brush caps are accessible from the outside of the motor housing with a screwdriver. Slide the worn brush out, insert the new one spring-side first, and confirm the brush moves freely in its holder.

Common questions

Q: Will this 5140033-19 carbon brush set fit my DEWALT DW745 table saw, or is it used on other DEWALT models too?

Yes, this brush set is specifically matched to the DEWALT DW745 motor, so it’s a direct replacement for that saw when the original brushes are worn. If you’re checking another model, it’s best to verify the exact part number in your saw’s parts list, since brush size and lead configuration can vary between DEWALT tools.

Q: How do I know if the carbon brushes on my DW745 need to be replaced with this 5140033-19 set?

Common signs include the saw cutting in and out, reduced power under load, excessive sparking at the motor, or the motor not starting consistently. If you remove the old brushes and they’re worn very short, chipped, or unevenly worn, it’s a good time to replace both brushes as a set.

Q: Is there anything important to know when installing these replacement brushes in a DEWALT DW745?

Make sure the saw is unplugged first, then install each brush in the same orientation as the original so it moves freely in the holder. After installation, run the saw with no load for a few minutes to help the new brushes seat properly against the commutator and reduce premature wear.

Before you buy — how to verify fitment

  1. Find your trimmer model number. It's usually on a label on the motor housing, battery slot, or lower shaft.
  2. Check spool compatibility. Compare the model number with the compatibility list above.
  3. Verify line gauge. Confirm the line thickness matches what your trimmer head requires by checking your manual or the old spool.
  4. Inspect the spool housing. Make sure the spool diameter, cap, spring post, and feed style match your trimmer head.

Frequently asked questions

How do I know this spool fits my trimmer?

Check your trimmer model number against the compatibility list above. Then verify the line gauge (.065, .080, .095) matches what your trimmer head requires — it's usually printed on the spool cap or in the manual.

Can I rewind a pre-wound spool?

Yes. Once the factory line runs out, you can rewind the spool with bulk trimmer line of the same gauge. Pre-wound spools just save time on the first load.

How often should I replace the spool?

Replace the spool when the line no longer feeds properly, the spring loses tension, or the spool body is cracked. Under normal weekend use, a spool lasts 2–4 refills before the housing wears out.

What gauge trimmer line should I use?

Match the gauge to your trimmer's power: .065" for light-duty electric trimmers, .080" for mid-range cordless, and .095" for gas-powered or heavy-duty models. Using too thick a line can stall the motor.
