550 Motor prob

[Anonymous]

I have a 83 550Es with a bad connecting rod bearing. THe guy at the dealer said that I would have to have the crankshaft redone If I wanted to use it again, because It would be worn down and I couldn't just get a new bearing. is this true cuase if it is how can I get by this problem without spending hundreds

Your 83/ 550 has a plain brg crank If the brg is bad it will score up the mating surface of the crank shaft requiring the crankshaft surface to be reground or the crank replaced before installing a new brg---- Try and find a used one on ebay or a used engine. Just remember they mage the 550 in both the early 2 valve & the later 4 valve version.. IF you rebuild your engine make sure to wash everything

NO they are not interchangable
