  • the functional clearance between the rockers and the valves is altered over time during the use of the engine. A setting of this game is therefore necessary, for example every 1500 hours.
  • the turning step is performed by an operator who accesses the motor of the power group by a hatch disposed under the power unit and allowing access to the power unit. engine.
  • the rail vehicle is then placed above a pit, to allow the operator to access the power group engine through said trap.
