What is the Axle shaft diameter ?
What is the standard and minimum diameter of the axle shaft where the Hyatt rides !
Thanks
Thanks

1.062, I believe.

Considering that good Hyatt’s are getting hard to find, I have considered making some over sized axle shafts. Probably at least.005 bigger

Hello Les,
That is a great idea. I have a few hundred good Hyatt bearings of varying measurements and at this time they have limited or specific applications. We could then juggle the bearings based on their specs, to match inside or outside placements. Also, if they were made longer as well.
Thank you for your willingness to take on these projects that offer such a valuable contribution to our hobby.

Re: What is the Axle shaft diameter ?
Rather than trash an axle that could still have some life left, what about an over size bearing sleeve, that would be much cheaper I'm sure.

Re: What is the Axle shaft diameter ?
I’ll let Kerry solve it with the modified sleeves. I sure don’t need another project!!

Re: What is the Axle shaft diameter ?
Thanks for the replies !
I have the books now, but the one spec sheet is much handier
I measured 1.060 on my only Hyatt location, the right inner of my Ruckstell.
The bearing measures .497-.498, most on the larger side and smooth and even.
Have early safety hubs and bearings on the outer locations.

Re: What is the Axle shaft diameter ?
In Chaffin's axle book, he mentions using shim stock around bearing sleeves when the axle housing bore is oversized. It occurred to me that this could work to reduce the sleeve diameter to fit an undersized Hyatt bearing in a standard-bore axle housing. Have any of you tried this?
I have not mic'd my bearings yet but I know that I don't want to get solid roller bearings. I am leaning toward using the modern bearings but shimming is interesting to me.

Re: What is the Axle shaft diameter ?
Shim stock works just fine

Re: What is the Axle shaft diameter ?
The problem with altering sleeve thickness, axle diameter & adding shim to compensate for worn Hyatt bearings, is that Hyatt rollers do NOT wear evenly, without taper. When using a tapered roller, because of the differing circumference of each end, one end will tend to "skid" on the axle & sleeve and cause premature wear. The different circumferences will also tend to skew the roller to the drive shaft, which will twist the Hyatt cage and cause further accelerated wear. If you want to do any of the above alterations, it should also be coupled with Hyatt rollers that have been centerless ground to a consistent diameter.
