Also remove the silencer-to-cylinder head flange. The silencer is then free to be removed.
The heat exchangers just have two nuts holding each exchanger to the engine. These where difficult to remove. As with all these jobs,the most accessible nut is removed without a problem. Removing the lower nut is hampered by the pipe it secures. The first was removed with some difficulty and the second was removed by hack saw! This left four bolts sticking out the engine (two broken). Hopefully these can be removed and replaced.
The engine was now ready to be stripped down further.
