Diesel Injector repairs + pressure setting, Perkins 4.203 engine (CAV injectors)

These are the injectors of my Perkins 4.203 forklift engine with CAV injectors, the engine was smoking badly and misfiring sometimes, too.
Time for the 500 hour maintenance as i think that no one looked at these for a long time.
It turned out that 2 were leaking badly and nozzles were stuck, the #3 pintle was a real challenge to get out, so we applied some rather unusual method to get it out. Another one was a different type and all were low on opening pressure. one as low as 95 bar,
Standard setting for this engine should be 120bar.
All 4 now performing reasonably ok and the engine runs much better.
Episode #3 of the forklift story (coming soon) will show dismantling the first injector, this video shows cleaning, re-assembly and pressure setting.

The engine is not the best anymore, producing a lot of blowby, so every little helps, but sooner or later, i will need to rebuild it anyway.
Therefore i am happy with the result, even the injectors would need new nozzle kits to make them perfect.
