    Now the fun begins work to assemble the engines are not so easy with just a manual in English, but I will not do it myself so it will not be done

    Hi,

    I am not sure what stage your project is actually at but would advise you to keep your engine parts as clean as possible during the rebuild.

    The smallest piece of grit or dirt can and will scratch your bearings and or crank pins, if there is foreign material between the shell and conrod you can have a tight engine and damage the bearings as well.

    Always use lots of clean lube oil to lube everything as you reassmeble it.

    Having soft clean non linting rags is also a very handy thing to have when doing such major work.

    I was a time served (10,000 hrs) diesel mechanic before going to sea and during that time saw a lot of good engines damaged by the things I have pointed out above.

    Finally a late night in August, I again hear the sweet sound of a real diesel engine

    Hi Thanks for the always fun when its work is estimated at 05 I bought the boat and I have been renovated since then, but we go with her every season there are not many roamers in Sweden so therefore I like this web page

    I would suggest a healthy dose of skepticism about those guys. The picture of a failed piston crown is attributed to "detonation" in a diesel engine. :rolleyes:

    The failure was due to a faulty injector and/or overfueling in that cylinder. That type of crown failure is a classic example of over temperature and melting that leads to piston siezure and liner cracking.

    Hello, you're right, I and my mechanic has been laughing a bit at these pictures, but 8.2 liters DD is a complex engine and it is difficult to adjust but I bought all the tools on e-bay so we could do everything Luleå is an industrial city so there are many who can repair two stroke diesels

    It might be too late but you should radius the corners of those hull inserts.

    Hi,

    I think we are behind the times Marmot. They don't currently do it the way I was taught that's for sure.

    I recently had this very issue out with LROS 's finest and lost.

    Aren't they the bunch that surveyed the Titanic and the Derbyshire? :D

    I believe ABS rules for steel vessels <90 meters calls for a minimum of around 5 times the plate thickness for the corners of welded inserts.

    And I just checked, IACS standards call for 5t with a minimum 100mm radius. The last revision was in 2008 so the Lloyds man must have something the rest of us don't have yet.
