The engine started loosing oil pressure after in ran for 10-15 mins.  The machine sat for about a year and I had to move it. Put in new batteries and machine cranked with starting fluid ( not much ) . I lifted the bucket and it chattered so I throttled down and machine went dead. Added 5 gals of Hyd. fluid and went to restart but all engine would do was bump, fan would move about 1 1/2 per starter bump.  How hard is engine to rebuild? Could this be a spun main bearing? or any Ideas.  I've rebuilt plenty of gas engines but no diesels.

I thought a 7G has a 6cylinder 426 in it an overhaul kit is like 1200 bucks, if you need a 7000 series engine I have 2 new ones.
