The Wacker Neuson Water Tank Cap is a genuine OEM component designed for the BFS series floor saws, including the BFS735, BFS940, BFS1345, and BFS1350 families. As a direct OEM replacement, this cap is manufactured to the exact specifications of the original part, ensuring a proper seal on the water tank. It fits an extensive range of BFS floor saw configurations across multiple production runs, making it a versatile service part for operators and dealers supporting this equipment lineup.
Key Features
- OEM Seal Integrity — Manufactured to the same material and thread specification as the original, maintaining a leak-free seal on the water tank during blade cooling operation.
- Drop-In Replacement — Threads directly onto the water tank fitting with no modification; designed to match the original cap's thread pitch and seating geometry.
- Broad BFS Series Coverage — Compatible with BFS735, BFS940, BFS1318, BFS1335, BFS1345, and BFS1350 floor saw variants, including A, W, AL, ALS, AB, ABZ, and CN configurations.
- Protects Blade Cooling Performance — A secure, properly sealing cap maintains consistent water flow to the blade. A damaged or missing cap can cause pressure loss, water leakage, and inadequate cooling during cutting.
- Sourced from Wacker Neuson — Genuine OEM part backed by Wacker Neuson's parts program, ensuring correct fitment across the full range of supported BFS model numbers.
The water tank cap seals the coolant reservoir on BFS floor saws, which rely on a continuous flow of water to cool the diamond blade and suppress dust during concrete and asphalt cutting. Without a properly functioning cap, the tank can lose pressure or leak, disrupting water delivery to the blade and increasing the risk of blade overheating. A worn, cracked, or missing cap should be replaced promptly to keep the water system operating correctly and protect the blade during heavy cutting work.
