The Wacker Neuson Filler Cap is a genuine OEM filler cap designed for the RC110 ROPS, RC110 CAB, RC110p ROPS, and RC110p CAB compact track loaders. As a direct factory part, it meets the exact material and dimensional specifications set by Wacker Neuson — no guesswork on fit or sealing integrity. The is the correct OEM part number for all four RC110 and RC110p variants listed, so you can order with confidence knowing it matches your machine.
Key Features
- Sealed to OEM Specification — Manufactured to Wacker Neuson's original material and thread tolerances, ensuring a proper seal against contamination and fluid loss every time.
- Direct Drop-In Replacement — Threads directly into the original filler neck on RC110 and RC110p machines with no rework or adaptation to the surrounding components.
- Broad RC110 Series Coverage — A single part number covers the RC110 ROPS, RC110 CAB, RC110p ROPS, and RC110p CAB, making it the right choice across the full compact track loader lineup.
- Contamination Protection — A correctly seated filler cap keeps dirt, debris, and moisture out of the fluid reservoir, protecting internal components from accelerated wear.
- Fuel System Safety — A secure, properly sealing cap prevents fluid vapors from venting uncontrolled and reduces the risk of spill or fire hazard during operation and refueling.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this is not an approximation — it is the same component installed at the factory.
A filler cap seals the access point to a fluid reservoir — whether for fuel, hydraulic fluid, or engine oil — keeping the system closed during operation and preventing outside contaminants from entering. When a filler cap cracks, warps, or loses its seal, it creates an entry point for dirt and moisture that can degrade fluid quality and damage downstream components. A worn or missing cap can also allow fluid to escape under vibration, leading to low fluid levels that go unnoticed until a more serious mechanical failure occurs.
