I said that wrong. They should have noticeable radial play but axial play (thrust) should be virtually imperceptible. I'll edit my original post.
In-out=bad. Side to side=good.
after running my K24 today, i felt the clearances again, and the axial (thrust) clearance is tight, undetectable.. there is a TINY bit of radial clearance tho, just as should be..
One of the few times when getting the ol' "in-out" ain't a good thing............
After reading this I ran down to the shop to check on the k03 on my AHU. After 430,000kms there is no.. In and Out play being pushing the shaft parallel with the ground, and just a bit of up and down play.. the fins towards the compressor housing.
