Makita 422584-2 Spare Part - BUMPER DTW300
Makita 422584-2 — Bumper / shock ring (original Makita)
Restore the impact-absorbing bumper that protects the anvil and housing with the genuine Makita 422584-2. This small, molded elastomer bumper (listed as a “bumper” or “shock ring” in parts breakdowns) sits at the rear/impact area to absorb blowback, reduce metal‑to‑metal wear on the strike piece and housing, and keep the impact mechanism running smoothly.
Key details
- Part number: 422584-2 (Makita). Sold as a single replacement bumper.
- Function: shock/impact damping between the strike piece/anvil and impact housing to limit wear and protect the gearbox/strike components.
- Construction: molded elastomer/rubber-style bumper designed to fit the impact housing recess and resist repeated impacts.
Example fitment (models this part is commonly listed for)
- Makita XWT14 / XWT15 series (XWT14T, XWT15T, XWT15Z and variants) and related XWT models.
- Makita DTW/ TW impact wrenches (DTW300, DTW302 and some TW004G / TW005G variants).
Notes for repair
- Replace with the exact Makita 422584-2 bumper to ensure correct fit and function; it installs into the impact housing recess and is a direct swap for the listed models.
If your impact wrench is showing excess play at the anvil, louder-than-normal impacts, or accelerated wear of the strike piece, replacing this bumper will restore the intended damping and protect the internal parts.
