whman01 15 #1 Posted September 28, 2018 I have worked on many Wheel Horse tractors and one thing I find on many of them is the wheel hub is wallowed out in the keyway. This allows the hub to rotate slightly on the axle. This will give a feeling of slippage in the drive train or transmission. I have even found them with a piece chipped out of the axle. I know it is important to keep the setscrew tight to keep it from movement. Anyway, has anyone found a way to repair these hubs short of replacing them? 1 Share this post Link to post Share on other sites
Achto 28,927 #2 Posted September 28, 2018 The key way in the hubs on my last build were worn quite bad. What I did was broach a new key way 90 degrees to the old one. I then drilled & tapped holes above the new key way for a set screw. The original set screw hole I used for a second set screw against the axle. This tractor is used to pull a mold board plow & so far I have had no trouble. If you don't have a broach set, a machine shop should be able to do this for you quite reasonably. 2 5 Share this post Link to post Share on other sites
WHX?? 50,901 #3 Posted September 28, 2018 (edited) Age old and pretty common problem here. If it's not wallowed out to bad or the axle is not too bad you can go with a new woodruff and add a second setscrew. Another alternative is to broach a new keyway in the hub. Others have used JB weld to or welded and reground to fix the chipping. Talk about posting at the same time Dan!!

whman01 15 #4 Posted September 28, 2018 That sounds like a good idea. Its better than the JB Weld I thought about using. I will check with my machinist friend. Thanks. 2 Share this post Link to post Share on other sites
