you can go to universals web sit and download the data for the engine, Unfortunitly for you the last newport I worked on we loaded on a truck for the delta about 2 this after noon.
I beleave the rear mounts are on the trans. so if that is the case and you take out the trans, who sits in there holding up the engine. and just servicing the trans from that port lazaret is the pits.
download the hurth manual, fight through the fact it is writen in 4 languages and go from there.
It's not that much more work after you undo the shaft. to pull the engine.
as I remember the trans comes off but I think the bolts are on the inside check the manual.
