Genuine Makita Rocker Cover Complete — part no. 140B46-7.
This is the complete rocker (valve) cover that fits over the cam/rocker assembly on a range of Makita small-engine garden and pump units. It’s supplied as the cover assembly (the mating gasket and retaining fasteners are shown as separate parts on the parts diagrams).
Example models where Makita lists 140B46-7 in the parts breakdown include brushcutters and blowers such as EBH252U / EBH253U, BHX2500 , EM4250 , PB2504 blower , EW120R / EW1050H pumps, and ER2550 / ER2550LH trimmers. Use this part when your machine’s original rocker cover number matches or when the parts diagram shows 140B46-7 as the cover.
Installation details: the cover mounts with three M5 × 16 fasteners (listed separately on the diagrams) and pairs with Makita rocker-cover gasket part 162275-0 (gasket sold separately). Listed as 140B46-7 is shown as a replacement for part 140023-7.
Condition note: this is the original Makita cover part designed to restore correct fit and sealing where the factory cover is cracked, broken or warped; confirm fit by checking your tool’s model and the parts diagram to match part 140B46-7 before ordering.
