Hi all I have an old dumper truck with a Lister TS3 engine. firstly I’m trying to find a crank handle for it? Before I can find one I need to know if it clock wise or anti clockwise turning? see number on engine is 350 525TS3A07 there was another number stamped on the engine elsewhere : S 203 3100T any info appreciated and apologies in advance for not being a boater and for being mechanically thick 😬 cheers Joe
