I've actually done similar. Got some muriatic acid and let the crankshaft sit in it for a few hours and cleaned the aluminum off the crank journal from the connecting rod.

To be fair this was on a 9hp snowblower engine, I wouldn't attempt that on an S54.

Edit: This also likely wouldn't work because I believe the bearings in the S54 are lead not aluminum.
