Garrett 2674A817 GT2556S Turbocharger Assembly

The Garrett GT2556S turbocharger (Perkins OEM 2674A817, Garrett 785827-5010S) is engineered for Perkins 1100 Series 4.4-liter industrial diesel engines, specifically the 1104D-44T and Vista 1104DM variants. The unit integrates a high-efficiency centrifugal compressor wheel and a pressure/vacuum-controlled wastegate divert-air valve for precise boost regulation under Tier 3 emission standards. Constructed with nickel-alloy turbine housing and aluminum compressor housing, the rotating assembly undergoes high-speed CHRA balancing to ISO 1940-1 G2.5 grade. The turbocharger mounts directly to the Perkins 1104D exhaust manifold flange and oil feed/drain interfaces without modification. Compatible with industrial applications including excavators, wheel loaders, backhoe loaders, skid steer loaders, agricultural tractors, and Linde 352-05 forklifts.
