Can someone tell me in general what needs to be removed or disconnected on the flywheel side of a 763? (v2203 engine) I'm an experienced mechanic but never any major repairs on a bobcat. I can't tell from looking at it if there is an outer bellhousing with bolts then the engine slips out or some other arrangement that attaches the engine/flywheel to the pumps. My overall problem is extremely hot blowby out of the valve cover with my engine oil in it. It will blow a quart of oil in a few minutes. I have a good head standing by to swap but the more I read/research, all articles on diesels point straight to rings or cylinder. If someone else has had this problem I would like to hear the fix!!!
