The Wacker Neuson Rain Cap is a genuine OEM component designed for the APT6S, APT6T, APT8S, and APT8T pump series, including standard, surge brake, electric brake, and cold weather configurations. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation without guesswork. This rain cap fits the full range of APT6 and APT8 pump models, covering both skid-mounted and trailer-mounted variants across all available brake and climate options. Keeping the correct cap in place protects engine air intake components and preserves the operational integrity of your pump.
Key Features
- OEM-Matched Intake Protection — Manufactured by Wacker Neuson to original design tolerances, ensuring the cap seals and deflects moisture exactly as intended for this pump series.
- Drop-In Installation — Engineered to mount directly onto the existing air intake fitting with no trimming, adapting, or hardware changes required.
- Broad APT Series Coverage — Fits APT6S, APT6T, APT8S, and APT8T pump models, including surge brake, electric brake, and cold weather variants, both skid and trailer-mounted.
- Keeps Intake Passages Clear — A properly functioning rain cap prevents water, debris, and contaminants from entering the engine air intake — a failed or missing cap risks ingestion damage and unplanned engine repairs.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5200021813 carries the full confidence of OEM supply chain quality and traceability.
A rain cap sits at the top of the engine air intake stack and acts as the first line of defense against rain, debris, and airborne contaminants entering the engine. By deflecting water and particles away from the intake opening, it allows the engine to draw in clean air even in wet or dusty field conditions. When a rain cap is cracked, missing, or improperly seated, moisture and debris can bypass the air filter system entirely, leading to accelerated engine wear or, in severe cases, hydro-lock — making timely replacement an essential part of routine pump maintenance.
