I cant find any main bearings (hauptlager) in repair sizes for the 990 engine. There seem to be bearings for the 983. But according to mercedes documents 2.3 bearings are thinner then 2.5, and will not fit in a 990 engine.
We measured our 2.5 crankshaft (kurbelwelle), and indeed its seems to be thinner bearings in our engines.
Are there main bearings available for the 2.5 in repair sizes?
