Makita 136381-7 Spare Part - ANVIL M ASS'Y DTD157
Makita part 136381-7 — Anvil M assembly (original Makita) — direct replacement anvil for the hammer/bit-holder assembly in sub‑compact 18 V impact drivers. This machined steel anvil mates with the hammer to transfer impact force to hex bits and restores secure bit retention and consistent impact action when the original anvil shows wear or mushrooming.
What it is and why it matters:
- Part: 136381-7 (Anvil M Ass'y). Fits into the hammer/bit-sleeve area and works with the hammer/strike components inside the hammer case.
- Material/finish: hardened steel construction (machined anvil surface designed for repeated hammer contact) — typical for Makita anvil assemblies used in impact drivers.
- Bit interface compatibility: designed for tools with a 6.35 mm (1/4 in) hex shank bit holder.
Models this part is documented to fit (example models):
- Makita DTD157 (including DTD157Z variants).
- Makita XDT18 / XDT18Z / XDT18ZB (XDT18 series impact drivers list this anvil in parts/fitment references).
Practical notes for repair:
- The 136381-7 anvil is supplied as the anvil sub‑assembly; installation requires disassembly of the hammer case and replacement of the worn anvil and any accompanying small parts (balls, springs, washers) if they show wear — consult the tool’s exploded parts diagram for exact reassembly order.
- Restoring a worn anvil typically eliminates bit wobble, improves impact transfer, and prevents premature damage to bits and the hammer.
If you need a drop‑in anvil that matches the factory specification for Makita sub‑compact 18 V impact drivers (DTD157 / XDT18 series), part 136381-7 is the original Makita replacement specified in the service parts diagrams above.
