Has anybody used Devcon Titanium Putty or something similar to fix worn splines? I purchased a used 5' tiller this past winter at an auction. Now, after checking it over, I see why it was up for sale. The splines on the clutch hub and input shaft have an extreme amount of wear. I would guess at least 50-60% gone. I read somewhere that John Deere made a repair kit for this type of problem on some of their older dozers (2010 and 420) and it was a repackaged version of this epoxy. It seems like a really high load area to be using an epoxy. The tiller dealer wants $750 for a new shaft and $500 for the hub so it has me searching for a cheaper alternative as this tiller is just for working up the garden once a year. The Devcon product isn't cheap either at $100 but I'd be willing to give it a try if I someone's had good luck with it in such an application. Another thought was just to weld the hub solid to the shaft and run it until it fails and go from there if and when the time comes. Thoughts anybody?
