The Wacker Neuson 5200019871 Cap is a genuine OEM component designed for LTN4Y and LTN5Y series light towers, as well as APT4T and APT4S trailer-mounted pump units. As a direct OEM replacement, this cap is sourced to the same specifications as the original part installed at the factory, ensuring a consistent, correct fit across all compatible configurations. Verified fitment covers a wide range of LTN4Y and LTN5Y variants — including 60Hz, 120V/60Hz, SA, RH, CH, UK, HD, and cold-weather editions — alongside APT4T and APT4S pump models in both surge brake and electric brake configurations.
Key Features
- Genuine OEM Construction: — Manufactured to the same material and dimensional standards as the original cap, ensuring consistent sealing performance and a secure fit every time.
- Drop-In Replacement: — Replaces the original cap directly with no modification to mounting points or surrounding components required.
- Broad Fitment Coverage: — Compatible with the full LTN4Y and LTN5Y light tower series, plus APT4T and APT4S trailer-mounted pump units across multiple regional and voltage configurations.
- Protects Critical Access Points: — A properly seated cap prevents contamination, moisture ingress, and debris from reaching the port or reservoir it covers, protecting downstream components from premature wear.
- Verified Part Number: — Part number 5200019871 is confirmed against Wacker Neuson OEM documentation for all listed models, giving you confidence before you order.
A cap serves as a protective closure for a fluid port, reservoir opening, or access point on the machine. Its primary role is to maintain a sealed environment that keeps contaminants — including dirt, water, and debris — from entering the system. When a cap is cracked, missing, or no longer seals correctly, it exposes the underlying port to contamination that can damage pumps, valves, or fluid systems over time. Replacing a worn or damaged cap promptly with a correctly specified part restores that protection and keeps the machine operating as intended.
