The crankcase (i.e. oil sump) part number for the A28NER engine is 12 623 431 and the part number for the B284 crankcase is 12 602 089. When you eyeball the exploded view for the parts diagram the aluminum case pretty much looks the same. Maybe the parts numbers are different because the internals for each engine type are different. Million dollar question - can you use a B284 casing with A28NER internals? Have a look yourself ....https://www.esaabparts.com/viewparts.php?searchpart=1§ion=61931784 (A28NER) and https://www.esaabparts.com/viewparts.php?searchpart=1§ion=514558395 (B284)...
