This listing features a premium-grade rotary Fuel Injection Diesel Pump, officially identified by part number 9320A535H. Specifically engineered for the Perkins 1100 series, this DP210-type mechanical assembly serves as a direct replacement for the OEM reference 2644H509L. It ensures exact hydraulic timing and volumetric fuel delivery across the four-cylinder firing order, maintaining the precise injection pressure curves required for Tier 2/Stage II emission-compliant industrial applications.
The 9320A535H/530H/536H is calibrated exclusively for the Perkins 1104 Diesel Engine, a 4.4-liter turbocharged and aftercooled powertrain widely utilized in backhoe loaders, telehandlers, and power generators. This pump utilizes an internal mechanical governor and an advanced boost compensator to manage fuel-to-air ratios dynamically. By adjusting the fuel rack based on turbocharger boost pressure, the 9320A535H/530H/536H ensures maximum torque backup and prevents excessive particulate emissions during rapid load pickup.
Installing this factory-calibrated Fuel Injection Diesel Pump resolves common 1104C operational issues, such as difficult hot-starting, engine hunting at idle, and power loss under hydraulic load. Replacing a worn unit with this brand-new 2644H509L assembly eliminates internal pressure leakage and restores the specific atomization pattern required by the Perkins 1104 combustion system. This ensures your off-highway equipment maintains optimal fuel efficiency and long-term operational uptime in demanding work environments.
