The Wacker Neuson Water Tank Cap 51Mm Dia is a genuine OEM replacement designed for the BTS 13 and BTS 11 gasoline cut-off saws. Sourced directly from Wacker Neuson, this cap matches the original component specification and seals the on-board water tank that feeds blade cooling during cutting operations. It fits the BTS 13 cut-off saw with 1-inch arbor and the BTS 11 cut-off saw with 7/8-inch arbor, making it straightforward to confirm the right part for your machine before ordering.
Key Features
- OEM-Grade Seal Integrity — Manufactured to Wacker Neuson's original material and dimensional specification, ensuring the cap forms a consistent, leak-free seal on the 51mm water tank opening.
- Direct Thread-On Replacement — Engineered to the same 51mm diameter as the factory cap, so it threads onto the existing tank neck without any modification to the saw.
- Confirmed Fitment — Verified for the BTS 13 (1-inch arbor) and BTS 11 (7/8-inch arbor) gasoline cut-off saw models.
- Protects Blade Cooling Performance — A properly sealing cap maintains water pressure and flow to the blade, preventing overheating and premature blade wear during wet cutting.
- Fuel and Chemical Resistance — As a genuine OEM component, the cap material is rated to withstand prolonged contact with water and the residues typical of cut-off saw operation.
The water tank cap seals the reservoir that supplies water to the blade guard during wet cutting operations on gasoline cut-off saws. This continuous water flow cools the blade and suppresses dust at the cut line — both critical to blade life and operator visibility on the worksite. A cracked, lost, or poorly fitting cap allows the tank to drain prematurely or leak, interrupting water flow and forcing the operator to stop cutting to refill or risk running the blade dry.
