281L Series

The Chelsea 281L Series Power Take-Off (PTO) reflects Parker Chelsea’s continued focus on evolving vocational vehicle requirements. Designed specifically for Allison 3000 and 4000 series transmissions, the 281L is engineered to provide additional space for mounting larger hydraulic pumps while maintaining reliable medium-duty performance. Building on the proven design of the 281 Series and incorporating extended shaft concepts inspired by the 871L platform, the 281L Series bridges the gap between medium- and heavy-duty PTO solutions. It delivers an optimized balance of size, strength, and efficiency for applications that do not require the full heavy-duty capacity of higher-output models. With its extended shaft Powershift design, the 281L Series improves installation flexibility while maintaining compatibility across a wide range of Allison transmission configurations. Pressure lubrication is included to support long service life and consistent performance under demanding operating conditions. The Chelsea 281L Series PTO is commonly used in utility trucks, light dump trucks, refuse vehicles, and defense or rescue applications where space efficiency and dependable medium-duty power are required. Key features include an engine-driven configuration, extended shaft design, pressure lubrication, and broad compatibility with Allison 3000/4000 transmission options.
