Need help guys for the C32 Crankshaft bearing and Rod Bearings!!
Hello everyone!
I am facing the problem of a engine knock which could be due to crankshaft or rod bearing worn out problem, therefore i planned to do a engine rebuild for the M112K, sadly when i search for parts for the crankshaft bearings its not listed available everywhere on the internet! Garage told me WIS indicate M112K crankshaft is using A 113 030 00 40 but it wasn't available, so the garage recommend to use A 112 030 00 40 for it. Besides that, they are also difficult to source Rod bearing as well, C32 using A112 030 02 60 and there are only A112 030 00 60 available. Anyone knows that if the M112 NA engine parts can be use for M112K SC engines? Especially Crankshaft bearings, Rod Bearings and Piston Rings! Thank you very much for your kind assist!!
Thank you my friend! Now it is confirmed Thrust Bearing and Crankshaft bearing are M112 and M112K compatible but Wrist brushing and Rod Bearing are not. Does anyone tried to use M112 Wrist and Rod bearing in a M112K engine?

I haven't been on these forums long, but I haven't noticed any threads in my searching around that involve anyone tearing into the internals of their M112K. From what I have read, though, the AMG engine uses different pistons and connecting rods, so there is a very real possibility that some of the bearings differ.
You probably know this already, but it's worth making sure - you can use very inexpensive "plastigage" to easily (and accurately) measure the clearance in your main bearings and lower rod bearings. If it were me, I would start by doing that just to confirm suspicions about where the problem is.
