Makita 168620-7 — Metering Diaphragm Assembly (original Makita)
Keep your 2‑stroke Makita brushcutter or power‑head running smoothly with the genuine Makita 168620-7 metering diaphragm assembly. This precision molded membrane sits in the carburetor’s metering/pump chamber and regulates fuel flow and pump pressure; a cracked, hardened or slack diaphragm will cause hard starting, flooding, poor throttle response and loss of power.
What you’re getting
- The metering diaphragm assembly (part no. 168620-7 / 1686207), supplied as the replacement diaphragm/pump membrane used in Makita carburetors.
- Typical construction: flexible rubber/elastic membrane and gasket interface designed to restore the carburetor pump action and correct fuel metering.
Fits (example models)
- Common compatible models include DBC260L, DBC260U, EM2600L, EM2650LH, EB7650TH, EB7660TH, EH5000W and BHX2500 / BHX2501 among others — check your model’s parts list to confirm fit.
When to replace
- Replace the diaphragm if it’s visibly cracked, hardened, stretched or if the machine shows fuel‑delivery symptoms (hard starts, flooding, poor idle/throttle). The service manual shows the diaphragm separated by four screws from the carburetor and describes removal/replacement steps.
Notes
- Supersedes/referenced alternate numbers used in parts listings: 1686207 (no space). Verify the part number against your tool’s exploded parts list before ordering.
