Unimog flywheel bolts
 

Sorry I don’t have a lot of info at the time. Never had mog but always wanted one. Came across a unimog For sale that the flywheel bolts came off or loose. Is this as simple as pulling the engine and putting new bolts in? I have no issues taking things apart but more Or less how difficult the parts are to get

What motor?
If those bolts came loose during operation, that would mean, its expect the worst, hope for the best. If they did not come loose while running, then how did they? Improper installation is a possibility. I guess, if the crank threads are buggered, you could possibly tap them to the next size up and find oversize bolts of the correct type. I would be leery of using thread replacement kits in that area. If the motor has a car application, the bolts should be similar.
