Kostas,
My 4200 has crankshaft side to side play as well. I'm not sure how much but I could put a dial indicator on it if you like. I would guess around 0.25 mm
I doubt that is an issue.
Thanks Tim,i think that mine is around there as well.I didn't write it correct.The bearings are indeed a press fit to the cases.i meant if the crankshaft is a press fit to the inner race of the bearing.I think that the play is between the inner race and the crankshaft but i assume it is normal.
