Original Makita 424888-8 — Bumper / damper designed to restore the shock‑absorbing cushion on your impact driver. This small rubber bumper fits the DTD153 impact driver — it installs in the front / head area to reduce metal‑to‑metal impact and protect the housing and internal components.
Made from resilient elastomer, the part is listed as a single bumper (qty 1) in the Makita parts breakdowns and is intended to be replaced when torn, compressed or missing to keep the tool running smoothly and to limit wear on the anvil and housing.
Approximate dimensions commonly shown for this bumper are about 28 mm (inner) × 42 mm (outer) × 10 mm thick — a compact ring that slips into its locating recess.
If your DTD153 has a chewed, flattened or missing bumper, the original Makita 424888-8 will restore correct clearance and cushioning so the impact mechanism and exterior shell aren’t repeatedly stressed.
