Wacker Neuson 5000126940 Filter Cover

The Wacker Neuson Filter Cover is a genuine OEM component designed for the BFS series walk-behind floor saws, covering a wide range of models including the BFS 935, BFS 914, BFS 940, BFS 1318, BFS 1335, BFS 1345, and BFS 1350. As a direct factory replacement, this cover is built to the exact specifications of the original part, ensuring a proper fit over the air filtration assembly. Compatible across gasoline-powered BFS floor saw variants including standard, AL, ALS, AB, ABZ, and AS configurations, this part covers virtually the entire BFS product family.

Key Features

• Genuine OEM Construction — Manufactured to Wacker Neuson's original tooling specs, ensuring the cover seats flush and retains the filter element securely under vibration and cutting loads.
• Drop-In Replacement — Mounts directly to the existing filter housing on BFS floor saws with no additional hardware or modification to the airbox assembly.
• Broad BFS Series Coverage — Fits the BFS 914, BFS 935, BFS 940, BFS 1318, BFS 1335, BFS 1345, and BFS 1350 across multiple build variants, including AB, ABZ, AL, ALS, AS, and A configurations.
• Protects Engine Airflow — A correctly seated filter cover prevents debris, concrete dust, and slurry from bypassing the air filter element, protecting the engine from accelerated wear during slab and pavement cutting.
• Dust Environment Rated — Floor sawing generates some of the heaviest airborne particulate loads of any construction task; a damaged or missing filter cover allows abrasive dust to reach the carburetor and cylinder, making this a high-priority replacement item.

The filter cover on a walk-behind floor saw serves as the outermost protective barrier for the engine's air intake system. It holds the air filter element in place and shields it from the high volumes of concrete dust, silica, and water slurry produced during cutting operations. When the cover is cracked, warped, or missing, the filter can shift or become exposed, allowing abrasive particles to enter the carburetor and engine — leading to increased wear, rough running, and potential engine damage. Replacing a damaged filter cover promptly is one of the lowest-cost ways to preserve engine longevity on a heavily used floor saw.
