Is knurling acceptable on a bearing journal.

[eugene13]

I've used JB weld on a boat trailer spindle, sold the boat 6 years later, no problem.

When I was still working in a machine shop we used to braze weld the shaft and just turn it down to size. Easy job
By knurling the shaft the bearing would seat on a lot of high spots and will eventually wear down after a few bumps and your bearing will be loose again.

Thank you all for all your advices, i completely forgot that i have some loctite green bearing glue, i also forgot to mention that this is a easy to find replacement part, they are 2-30$ new. That said i decided to take a chance as i'm reusing the bearings and just do a fine knurling and use some loctite bearing glue, if it fails i'll do the bearing conversion where i'll bore the upright to accept a sealed wheel bearing and never worry about them again, this is one of the common problem spots on this vehicle.

, or built up with weld or brazed and then machined to size and concentricity.

+1, I've done that a few times and it worked out better than expected, there's a risk of warping the part but proper temperature setting, small/short beads should take care of that.

I did the repair, the setup was really simple, i grabbed the hub by the wheel centric ring and supported it with a live centre, and used a fine knurling tool and some cutting oil and this is the out come.

I ran the machine shop in a electric motor repair facility for 20 years. We usually had a couple bearing fits a day to repair. We most always used the spray powder method. Some of the shaft fits were in excess of 8 to 10 inches in diameter. Took a long time to spray the powder on the shaft but if you were good at it you could true the journal up with minimal machine work after the powder cooled.
