The Wacker Neuson 5100066108 is a genuine OEM Engine 3TNV80F-NXDWN1 (EPA 4) designed for the PT6Y and PT6YT series self-priming centrifugal trash pumps. As a direct OEM replacement sourced through authorized Wacker Neuson supply channels, part number 5100066108 delivers the exact fit and emissions compliance your machine requires. This engine is confirmed to fit multiple PT6Y and PT6YT configurations, including standard, tank-integrated, and international variants. When the power unit on your PT6Y or PT6YT is worn, damaged, or non-compliant, this is the correct factory-spec replacement to restore full pump performance.
Key Features
- EPA Tier 4 Compliant Power Unit — The 3TNV80F-NXDWN1 designation confirms this engine meets current EPA Tier 4 final emissions standards, keeping your pump legal for operation on regulated jobsites.
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this engine is built to the exact displacement, output, and interface specifications of the original unit — no adaptation or retuning needed to mount and run.
- Broad PT6Y and PT6YT Fitment — Verified for use across PT6Y and PT6YT pump configurations, including standard, AU, and tank-integrated variants covered under multiple machine numbers.
- Restores Full Pumping Capacity — The PT6Y and PT6YT are high-volume 6-inch discharge trash pumps; a worn or seized engine means zero flow output. Replacing with 5100066108 brings the pump back to its rated performance immediately.
- Emissions and Compliance Critical — Engine replacement on EPA Tier 4 equipment requires a compliant power unit. Using a non-compliant substitute can result in permit violations or equipment rejection on regulated worksites; this OEM unit eliminates that risk.
The engine is the primary power source for the PT6Y and PT6YT self-priming trash pumps, driving the pump impeller to move high volumes of water containing solids, debris, and slurry. Without a functioning engine, the pump produces no flow — making engine condition the single most critical factor in pump availability on site. The 3TNV80F-NXDWN1 is a Yanmar-based diesel engine configured specifically for this pump application, and when the original unit fails due to hours, mechanical damage, or emissions non-compliance, a like-for-like OEM replacement such as 5100066108 is the only way to ensure the pump returns to its original rated output and regulatory status.
