This GT2556S turbocharger is listed for Perkins EPA Tier 3 mechanical fueling applications, including Perkins 1104 engines in agricultural and construction equipment. Representative OEM reference numbers such as 768524-0005 and 785827-0005 help confirm fitment for specific engine codes. Applications include Caterpillar C4.4 engines in wheel loaders and backhoes, as well as generator sets from Aksa and Grandwatt. Verify your specific engine serial number, production year, and fueling system configuration against these reference applications before ordering to ensure the correct turbocharger configuration is selected.
Technical Notes
The GT2556S configuration is visible in the studio photography, showing a two-part construction with a cast turbine housing and a silver compressor housing. A cylindrical actuator is mounted on top of the compressor housing, with visible related hardware pins and hex-head bolts securing the central bearing housing. Water-cooling or oil supply ports are visible on the compressor housing. These visual features help buyers verify the physical configuration against their existing unit. Verify the actuator type, cooling connections, and flange orientation before ordering to ensure the replacement unit matches your specific engine installation.
