4 Clean disassembled nozzle on outside and inside in diesel fuel with a wooden stick, in particular the seat of the nozzle and the annular groove.
5 Clean injection holes of nozzle body with cleaning needle from cleaning set.
6 Immerse nozzle needle and nozzle body in clean diesel fuel and inspect sliding properties by means of drop test.
Drop test
When the nozzle needle is pulled one third out of the nozzle body and then released, it should glide down again onto the seat as a result of its own weight.
If this is not the case, the nozzle and the nozzle body must be replaced.
