The Wacker Neuson is a genuine OEM Oil Filter Cap designed for a wide range of Wacker Neuson walk-behind concrete trowels, trash pumps, and floor saws. This includes the CT36 and CT48 trowel series, PT3A centrifugal trash pumps, BFS floor saws, and select HPG power units. As a factory-sourced component, the is manufactured to the exact dimensional and material tolerances required by these machines, ensuring a correct, leak-free seal every time. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's exact thread profile and material spec, ensuring the oil filter housing seals without weeping or cross-threading under operating conditions.
- Direct-Fit Replacement — Threads directly onto the existing oil filter housing with no modification; designed to match the original cap removed from the machine.
- Broad Model Coverage — Fits CT36 and CT48 walk-behind trowel variants, PT3A trash pumps, BFS 1300/1350 series floor saws, and HPG50/HPG100 power units across multiple machine numbers.
- Protects Engine Oil System — A properly seated oil filter cap maintains system pressure and prevents contamination ingress; a cracked, stripped, or missing cap can lead to oil loss, contamination, and engine damage.
- Fuel and Fluid Safety Relevance — On equipment used around concrete slurry and jobsite fluids, a secure oil cap closure prevents cross-contamination that can degrade oil viscosity and shorten engine life.
The oil filter cap seals the top of the oil filter housing, maintaining the closed lubrication circuit that keeps the engine's moving parts properly coated and protected. It prevents dirt, debris, and moisture from entering the oil system while also holding system pressure so oil circulates at the correct rate through the filter and engine. When this cap cracks, strips, or fails to seat correctly, oil can leak or become contaminated — leading to accelerated engine wear, low oil pressure warnings, or unplanned engine failures mid-pour or mid-cut.
