Getting the Doblo apart bit by bit. Have had a few problems with rounded nuts ect but have one I just can't shift. It is the Torx 18 bolt on the crank pulley. I understand that it is left hand thread but wanted to know if they are all left hand thread? It is just not budging at all. My torx 18 socket is new and I am using an 800 watt 230 volt impact wrench, rated at 500lb/ft. Had it a few years now and it has never failed yet. Am I missing something here? Any tricks to use?
To add to my woes, I drained the engine oil into a clean container for inspection later and had a look at the sludge in the sump. I have found 12 needle bearing rollers, any idea where they came from?
