The set of four Diesel Injector cutters ensures that the injector seat is bored to the exact dimension when replacing or reconditioning the diesel injectors, avoiding blow back and poor emissions.
Used for re-cutting injector seats when reconditioning the diesel injectorsSet included 19mm hexagon pilot, 2.5mm allen key and 4 cutters:
- 17mm flat cutter with 19mm external diameter for Mercedes-Benz CRD
- 15mm flat cutter with 19mm external diameter for other makes
- 17mm angles cutter with 21mm external diameter for Fiat, Iveco
- 17mm flat cutter with 17mm external diameter for BMW, PSA, Renault
Eventually these problems will affect the vehicles' ECU and cause over fuelling of the cylinder head.
Even after the diesel injector is removed, cleaned and a new copper washer fitted it may not always rectify the problem. Often the seat of the injector has been damaged due to constant erosion from escaping combustion gases.
The only way is to resolve this is to reface the injector seat.
