Flushing the Crank

[Oldshell4481]

what is the proper procedure to flush out the crank, what should i look for... the arm (brain Fart) that the piston goes on wobbles a bit.. is this ok?? and it makes grinding noises as i turn it.. bearings that i can see (left side) look ok..

there shouldnt be a grinding nois, there should not be ANY play UP and DOWN on the connecting rod, some side to side is ok aslong as its in spec...

there is no up and down play, just a little side to side... im going to flush it untill i no longer hear grinding.. i hope this crank is alright... the other motor knocks hard, and i need to get this one together to throw in it..

If there is any rust in there on the bearing surfaces its junk, rebuild it.....if you see rust on the crack weights then its prolly on the main bearings too and they need to be replaced
