Hey in the middle of a build-up. 4age SP, 7 rib block

I have done all the main caps/bearings etc.

While checking the normal thrust clearance (Sideways) it's perfect very little movement 0.015-0.020.

But while spinning the crank over I notice the thrust bearing itself slightly moving up and down and across, Not (sideways) am I making any sence?? :jamie:

Is this a problem?? Measures up identical to old set and no machining been done just a crank linish.

Any ideas???????????????
