bc.gold 3,403 #1 Posted January 21, 2021 A place to share ideas. From all the damaged and welded hubs mentioned on the forum it's obvious there's an engineering issue, the split lock hub would be a good choice once locked into place say goodbye to ruined keyways. 2 1 Share this post Link to post Share on other sites

Id like to see how those hub centers would hold up- a 'slice' of steel disc could be welded to those and bolt pattern drilled. Im also not against making them out of one solid piece and purchasing a broach.... If you choose to machine a hub from a billet, might be a good idea to machine the axle hole slightly smaller in diameter which would require a bit of heat to expand the hub for installation. This would assure the hub fits snugly, as the saying goes tighter than a nuns ! Formula to machine a shrink fit. Edited January 21, 2021 by bcgold 1 Share this post Link to post Share on other sites
ebinmaine 67,309 #3 Posted January 21, 2021 I'm familiar with those but only just a bit. I had to order one with a separate outer pulley to get the smallest sized engine pulley for Colossus. Share this post Link to post Share on other sites

bc.gold 3,403 #6 Posted January 21, 2021 (edited) Once the inner rim circle diameter is known the outside edge of this type of collar could be built up by welding then machined properly to size. Edited January 21, 2021 by bcgold 1 Share this post Link to post Share on other sites

Once the wheel cover is back on who cares what is hidden underneath. Edited January 21, 2021 by bcgold Share this post Link to post Share on other sites
Pullstart 62,803 #8 Posted January 21, 2021 I’m pretty sure @A-Z Tractor offers a reproduction split hub? Heating the hub for a press fit, would it ruin the seals just installing it? 1 Share this post Link to post Share on other sites

Heating the hub for a press fit, would it ruin the seals just installing it? Same practice applied to any shrink fit installation, sometimes the bearing is heated in an oil bath other times with a heat gun, the article may offer better suggestions, Proper Heating Practices for Bearing Installation Edited January 21, 2021 by bcgold Share this post Link to post Share on other sites

With what Industrial suppliers have to offer it's like having the adult version of a child's Meccano Set. Edited January 21, 2021 by bcgold 1 Share this post Link to post Share on other sites

Sounds expensive The part your looking at are produced by the thousands via CNC machining which keeps the cost reasonable. We have not yet arrived to the cost of ownership. Be my guess less than a $100.00 American dollars for the complete hub ready to install. Most of us could probably find that much loose change hidden in the chesterfield.

roadapples 6,983 #13 Posted January 21, 2021 I think too that AtoZ has them. Something over $100 if I remember correctly 1 Share this post Link to post Share on other sites
bc.gold 3,403 #14 Posted January 22, 2021 (edited) 1 hour ago, roadapples said: I think too that AtoZ has them. Something over $100 if I remember correctly Indeed he has. A-Z Tractor is now offering an axle hub for the 1" and 1 1/8" axles. This is called a repair hub. This hub is manufactured with a tapered hub that clamps down on the axle when installed. This will help with axles that have a worn keyway and axles that might be wore from bad hubs. Also this hub is very easy to remove for future repairs. To purchase these hubs you can either call A-Z Tractor at 1-717-821-2542 or you can go on the website at a-ztractor.com and purchase them on the sight. To find the repair hub on the sight just type in the part number of the hub you are replacing or type in repair hub. When these hubs are installed properly under most conditions the hub will not turn on the shaft even if there is no key installed. These hubs sell for $110 each and when you are purchasing you have to select the correct one for your shaft size. The same mounting hub is used just a different center shaft hub for the different size shafts. Edited January 22, 2021 by bcgold 1 1 Share this post Link to post Share on other sites

The split bub is currently selling under $10.00.US / $15.00 Canadian. Part Number, M - ( AMEC Hub SD 1 1/8 ). Now to locate the female companion, then have the large ring for the bolt circle laser cut with holes for thread tapping.

bc.gold 3,403 #17 Posted January 22, 2021 (edited) You'll find that only the teeth have been either flame or induction hardened, the rest of the sprocket is easily machined and drilled for tapping. Edited January 22, 2021 by bcgold Share this post Link to post Share on other sites
bc.gold 3,403 #18 Posted January 22, 2021 (edited) Is this the correct bolt circle 5 x 4.5" for the wheel horse rear rim. If I can find a nice dry block of wood maybe make the necessary pattern for the casting, I use Petrobond an oil based sand made primarily with Olivine so the finish comes out very smooth like the part was drop forged. Sand castings usually have a rough finished texture, which I suppose helps the paint and other crap to adhere. IMO the foundry was a bit skint on the metal.

ebinmaine 67,309 #19 Posted January 22, 2021 Bolt circle is correct. The pictured hub is an early type used up to 1975 or so. Later production were much thicker and didn't have the star like appearance. 1 Share this post Link to post Share on other sites

Really dig the 'taper lock' hub idea and did do some research on those but they looked expensive- mainly the outer hub. I'd think by the way those are designed, not even sure if a key would be needed haha. 1 1 Share this post Link to post Share on other sites

Maybe not necessary. 1 Share this post Link to post Share on other sites
bc.gold 3,403 #22 Posted January 22, 2021 (edited) 14 hours ago, bcgold said: A-Z Tractor Pro's and Con's The shrink fit I have suggested would give the full width of the hub's contact with the axle shaft full clamping force. The downside is that it would be very difficult for most novices to remove. The split hub offered from A-Z is the perfect fix, but as is would rate its use for rolling stock, show n shine or at best light duty work. Not particularly suited for plowing or tractor pulling. The clamping collar is narrow therefor the force applied is localized nearest the flange where it's least needed. Split hubs are relativly easy to remove.

ebinmaine 67,309 #24 Posted January 22, 2021 I'd have to measure a few. I dunno if it's a standard across the years though. Share this post Link to post Share on other sites
