Default Crank end play tricks ?

Hey All,

I started pre-assembly of my 428 yesterday, I started off with checking the main bearing clearances, all checked out at .002 ... then i lubed the bearings, torqued the crank starting with main cap 3,2,4,1,5 all to 100 ft/lbs and then cap 5 to 120 ft/lbs as instructed. My problem is this, I have zero crank end play. I set up the dial gauge on the crank centerline, zeroed it out, moved the crank in both directions. It would move .002 or so, but after I let off pressure it would settle back to 0.

Is there something that I missed, a trick for getting everything settled properly ? Or should i take the thrust bearing out and clearance it a bit to allow some movement?

Thanks !
