Crank end play, thrust bearing gap
 
Hey guys, I'm assembling my forged motor. I noticed my thrust washer and crank surface have a visible gap between the two. I measured the end play and it's at .009

My machinist tells me tolerance is .002 to .011

I can move the crank forward and backward my hand and this has me nervous. I've never put together a motor with crank walk in brand new form... seems crazy to me.

Press forward? Or is there a solution such as thicket thrust bearings? I have only seen one part number available.

Thanks

I heard somewhere that there are 4 different sizes for thrust bearings but cant remember where. Maybe call Mazdaspeed (800-435-2508)? I think that is too much endplay for a "new" motor as well.
