I can't get the chest from the combo van

Hello, I hope someone can help me because I can't get the bolt that goes in the crankshaft of the Chevrolet Combo Van 1.3cc. Year 2008 oil to be able to make a change of button packaging since oil is entering the water, I came to ask that I may turn the other way around since it is very tight and I could not get the workshop manual. I am waiting for answers please

I already knew that the bolt has a thread upside down thanks and that it can serve someone this data since it can cause a small headache. luck
