Makita 452047-4 Spare Part - OIL CAP ER2650/EM2651/EN4951

Genuine Makita oil filler cap — part number 452047-4 — a like‑for‑like replacement that restores the oil fill seal on Makita 4‑stroke outdoor engines. It’s a simple screw‑fit plastic cap designed to resist oil and weathering, so it prevents leaks and keeps dirt and moisture out of the oil reservoir; easy to remove and reinstall during routine maintenance.

Compatible with a range of Makita handheld and backpack models, including EB5300 (TH/WH), EB7650 (TH/WH), EB7660 (TH/WH) and several EM/ER/EN series brushcutters and blowers such as EM2650/EM2651/EN4951 and ER2650 — check your tool’s parts diagram to confirm exact fit for your model.

If your old cap is cracked, missing, or no longer sealing, replacing it with the original Makita 452047‑4 will restore proper oil retention and help protect the engine.

Fits, part function, and the “genuine Makita” designation are shown in Makita parts diagrams and service listings — the cap is a straightforward, low‑cost repair part to return your tool to reliable operation.
