Default Hatz Diesel Settings

Seeking assistance. I am replacing the cylinder head gasket on a Hatz diesel, Type ES75 247E
Model 161588185652
and was wondering if someone could furnish me with the Head Tightening Torque and the Inlet and Exhaust Valve clearances. I have a head gasket on order and am hoping to start reassembly later this week. The engine is on a vibrating roller and besides the gasket blowing it appears to have some fuel trouble as it will run for a minute ot two and then peter out, I found the filter had come adrift in the tank so am guessing that it has sucked some dirty fuel! No doubt I will sort it in the end.
Regards
Pete.

Thanks Jon, that would be great! I have emailed the Hatz factory for information but I think that a reply is unlikely!

WINDRUSH
in order to properly replce a head gasket on a hatz engine you need to determine the bumping clearance between the top of the piston & the bottom of the cyl head. They make different thickness head gaskets, put two small pieces of soft solder on top of the piston dirrectly over the wrist pin. Assemble the cyl head,with a gasket,torque head. Rotate the engine till you feel the solder flaten between the piston & head. Now you know what the clearance is, now you can do t
the math to determine what thickness gaket you will need.
If I remember right the bumping clearance should be about .020. If it is to tight damage will ocurre, to loose it will be hard to start.

Hey All
Thanks, this thread helped me out quite a bit!
I have a hatz e89fg that's down on power and has a leaky cylinder head, and would have just went blindly ahead without measuring. Do i understand correctly that you can't just measure the existing gasket?
Also Does anyone know what that knob under the hole in the valve cover is? It seems to act on a shaft that is in front of the injector spray. I'm wondering if it has anything to do with tuning.
50 nm Is about 38 foot pounds right?
All the best
Pete M.
