A repair procedure and new tools have been created to repair of the exhaust rocker compression brake pistons. In some instances the exhaust rocker piston cap screw may become loose and back out causing loss of engine compression, or a mechanical injector Diagnostic Trouble Code (DTC). This repair will require removal of the exhaust rocker piston, removal of the exhaust rocker piston cap and internal components for cleaning. Ensure the rocker arm and exhaust rocker compression brake piston are recorded as a pair during this repair procedure for proper installation. After cleaning, the internal components are re-installed, thread locker (LOCTITE 270) is applied to the cap, and the cap is tightened with special tooling to ensure the proper torque is applied.

Used with Volvo FEPRO0564 assembly tool.
