Make sure the fan isn't hitting the shroud or it will break.
To be honest I don't either, but it has always been easier for me to do with a cherry picker than lifting the engine by the oil pan. Maybe just the fact that I hook the picker to the right or left front only, so it lifts just the side I am working with.
I've change both motor mounts in my rig and just used a piece of wood on the bottom of the oil pan with a jack and it worked no problems.
Did you do them both at the same time?
If not, did you have the bolts loosened on the other side when you were changing a mount?
