Turbocharger with wastegate

A method of assembling a pressure control assembly of a turbocharger, the turbocharger comprising a turbine housing and a compressor, the pressure control assembly comprising a valve assembly mounted within the turbine housing, a pneumatic actuator mounted to the turbocharger to receive pressurised air from the compressor, an actuator rod extending from the pneumatic actuator, and a lever arm extending from the valve assembly and the turbine housing and linking the actuator rod to the valve assembly, wherein the actuator rod is a rod comprising a first elongate portion defining a first rod end, and a second portion defining a second rod end, said first and second portions being pivotally joined to one another to allow a degree of relative pivotal motion between said two portions in at least one plane perpendicular to the axis of said elongate first portion, the method comprising:

• assembling the valve assembly and lever arm on the turbine housing;
• assembling the pneumatic actuator and actuator rod as a sub-assembly;
• mounting the pneumatic actuator/actuating rod sub-assembly to the turbocharger;
• and
• securing the second portion of the actuator rod to the lever arm.
