hey guys my cousin brought me his 13 550 xp to look at run great but had a awful knock/rough noise sounded like a lower rod bearing loose. I have now pulled the engine and trans got it separated and found the nut that holds the engine "coupler" to the crank shaft loose ! anyone ran into this ? also should the coupler have movement ? or should it be relatively solid?…also ya I know didn’t need to pull the engine but it actually wasn’t bad to do and I can have it on the bench to work on
