I also use a fixed position chain fall and have done it both ways. If I was planning to swap the complete unit, I would take it out as one unit. You just have to place the lifting chain or straps (I prefer nylon straps) in such a position to be able to balance the unit slightly off level with the front of the engine high. It will take a bit of juggling to determine the proper position of the straps. I would replace it as a unit as well. Gar Williams
