Why are there 2 John Deere part numbers for a 120C Excavator reman turbo? There is SE501155 and SE501674
DZ121479 | John Deere 4045 4.5L Turbocharger (SE501155)
I see they are both listed as cross reference, but different prices according to John Deere. Is it the same turbo?

They have the same function but internal parts are not interchangeable and therefore requires separate reman numbers for the same machine. It was likely a running change. If the stock turbo on your application has a 2" oil drain bolt spacing, you will need RE509555 oil drain from John Deere to go with this turbocharger
