Technical Notes
The GT2556S turbocharger features a visible variable geometry actuator assembly mounted on the turbine housing, connected via a blue pneumatic hose. This configuration is associated with adjustable turbine vanes to manage boost pressure. Buyers should verify the actuator related hardware and hose routing against their specific Perkins 1104D-44T engine installation. Confirm that the square exhaust flange and machined compressor inlet align with the existing manifold and intake plumbing. Pre-shipment inspection includes visual checks of the turbine and compressor housings. Verify the wastegate flapper valve seating and shaft play before installation to ensure stable operation.
