You will always have alot of play on the l/h crank tail...this is why...
The tail is very long,nearly doubling the play at the actual bearing.
The main bearing is not an interferance fit on the crank or in the casing...not ideal, but makes rebuilds easy.
The bearing is c3 clearance to allow for expansion...c3s always feel loose.
So basically ...dont worry...its normal.
