I know it might be an obvious thing but I am knew to this tractor. My 155d I bought recently has a fuel leak and I think its coming from somewhere around the fuel injection pump specifically around a gasket maybe. I personally don't want to deal with timing if i don't have too. So, I'm hoping you wonderful people can guide me. Is there a gasket or is it just the shims? Do the shims do sealing like a gasket as well as timing?
