If your RIDGID® 700 power drive is sparking at the vents, losing torque mid-thread, or cutting out until you tap the housing, the carbon motor brushes are almost always the culprit. Brushes are a consumable — on a 700 that threads daily, expect to replace them every 1–3 years. The good news: it's a 15-minute job with a screwdriver.
Symptoms of worn brushes on a RIDGID 700
- Heavy sparking visible through the motor vents
- Loss of power under load (stalls threading 1" and up)
- Intermittent cut-outs; motor restarts after tapping or repositioning
- Burning/ozone smell after use
What you need
One set of 44815 carbon brushes for the RIDGID 700. Always replace brushes in pairs — a fresh brush against a worn one wears unevenly and arcs.
Step-by-step replacement
- Unplug the tool. Never open the motor housing with the tool connected to power.
- Locate the brush caps. On the 700 they sit on opposite sides of the motor housing near the rear vents.
- Remove each cap with a flathead screwdriver and slide the old brush and spring out. Note the orientation of the curved brush face — it matches the armature.
- Inspect the old brushes. If either is under about 1/4" of carbon, cracked, or oil-soaked, replace both. While you're in there, look at the commutator through the opening: deep grooves or blackening mean the 44055 armature (115V) is next on the list.
- Insert the new brushes curved-face toward the armature, seat the springs, and tighten the caps snug — not gorilla-tight.
- Run the tool unloaded for 5–10 minutes. Light initial sparking is normal while the new brushes seat to the commutator; it should settle down quickly.
If new brushes don't fix it
Persistent heavy sparking or a no-start after fresh brushes points to the armature itself. The 44055 replacement armature is a direct fit for the 700 power drive. And while the housing is open, it's a good moment to add the 42950 carrying case to protect the tool between jobs, and keep dies cutting clean with the 418 oiler bucket.
