Re: how to pull a motor?
I'm hung up on the words "runs flawlessly" and "preventative rebuild". Your business to be sure but 3700 hrs is not a lot for a well maintained diesel. Why not just do an oil analysis, see what that says, then go from there? If normal, why bother? You could have the injectors rebuilt. But why the effort of pulling and rebuilding? If it ain't broke.......
