There was a discussion on oil pumps in the past few months, and one commentor noted a small diameter hose was good for the Lofrans.
I would definitely not unbolt that beast if it wasn't necessary. Lots of wiring and it may be that there is an embedded plate with the bolt corroded fast.
Does anyone know if the mounting bolts can be just turned out (i.e. is there an embedded plate below the winch for the mounting bolts)??
