Makita 140S89-1 Spare Part - IMPACT BOLT A COMPLETE HR3001C

Makita 140S89-1 — Impact Bolt (Complete) for HR3001 series

Restore the hammer action in your Makita rotary hammer with this original Makita Impact Bolt assembly (part no. 140S89-1). This complete impact bolt sits inside the hammering mechanism and transfers the piston’s blow to the striker and bit carrier; it’s machined/heat-treated for impact resistance and precise fit so timing, energy transfer and wear characteristics match the factory design.

What it fits: designed for the Makita HR3001 family — commonly listed for HR3001C and HR3001CJ (30 mm SDS‑Plus combination hammers). Use this part when the internal impact pin/bolt is worn, mushroomed or bent and you want the original Makita fit and function.

Why choose this part: direct-fit, original Makita construction restores consistent impact energy, reduces vibration and limits premature wear of the striker/piston/tool holder — an exact replacement to get a beat-up HR3001 back to factory performance.
