Today checked the valves, two of them had way more space compared to 0.20 as specified, adjusted them.
Also got all the injectors out, very easy, so I guess Im mister lucky here
One of the bolts was already loose...hmm....not good
The hardest part was to move the second fuel line out of the injector since there is a little too less space if you want to leave the air intake manifold on.
They all look like this:

What do you guys think, dirty, very dirty or .....![]()
Also checked the spray patterns, the way the diesel sprayed out, oh boy you cannot call that a pattern at all
Because the tractor is in use these days I put them back and will clean them later.
However the tractor started much better already, so I guess the loose injector made a compression leak.
Any tips on cleaning the injectors?
Sounds like good progress. I have seen youtube videos on rebuilding/raking injectors apart and cleaning them. I have not done so.
Ditto on rScotty’s caution about fluid injection expand that to any fluid under pressure not just diesel and not just from injectors, even cracking a line can cause a high pressure spray—caution is the only way to proceed.
Since the tractor is being used, consider a diesel conditioner that will also clean the fuel system. Due to changes in diesel production over the last 30+ years, a conditioner additive is probably a good ideal for these engines.
