    Repairing PLD units (EUP)

    Repairing PLD units (EUP)
    PLD-unit is operating mechanism (solenoid valve). Operating mechanism – is injector – installed separately in the cylinder head and connected with PLD-unit by high pressure pipe.
    This injection system differs by high repairability.
    Fuel injector is done separately from PLD-unit. As at low quality of diesel fuel the first part that breaks down is nozzle of the injector. Injector can be removed and tested and, if necessary, be adjusted or repaired.
    PLD-units are mounted on the engine block. (repair of PLD-unit is close to the repair of unit-injectors (Bosch)). High pressure pipe connecting PLD-unit and injector is at open access. I.е., if necessary, it is possible to make diagnostic procedure with the lowest working hours directly on the car – measure pressure developed by PLD-unit.
    PLD-units Delphi and Smart Injector (DAF-105) are repaired in accordance with manufacturer demands with assigning new calibrating codes of original spareparts.
    Diagnostic and repair are done at specialized test benches.
