Got the old mower all tore down. New bearings due this evening.

One of the old bearings was turning on the hub at the OD. Not too much
wear but a new bearing is going to slide in there and still have room
to rotate.

I'll take a center punch and do a poor man's knurl job on the hub. But
I've seen that give out after a while. there must be some product to
lock it in place. "Locktight Super duper never let it go"

Any suggestions?

Loctite does indeed make a "super duper never let go" adhesive. 609 is
one of them. Properly applied it will not let go. A centerpunch knurl
is a poor substitute. Done correctly the bearing will not rotate in a
bore or on a shaft when Loctite permanent adhesive is used. It may be
wise to buy some primer too. The primers are specific to the various
products.
