rods seem to be fine they dont move back an forth but they do move a litte side to side which is normal right?

bearing material is non ferrous. so a magnet wont pick it up. if it does... wow you have mechanical issues with that motor. but yeah check your mains and rods and fromt that youll probably see where you need to go. doesnt help that its on a dark pizza box. dry it off and get it on some white paper. we will be better able to see what it is. looks like fariy dust right now to me.

normally you cant just change bearings without measuring them. who knows might be to tight and lock the motor up within a minute. might be too loose and knock all to hell. either way youll usually need a new crank and rods. if something really goes back a block due to the line bore of the crank being all fucked to hell and back from a spun bearing.

its not like brake pads where you just slap in some new ones. they have tight clearances that have to be met. and that takes taking the motor out and tearing it down to measure the crank. and put the bearing is the block and rods and measure the bore. and hope the crank is big or small enought to fit inside and have the right clearance between them.
