    Sparky and Nickel, thanks for the input. I was afraid pulling the axle was the only way to do it right but there are some pretty sharp guys on here that I was hoping would have a proven way to do the repair. I'll have to check out smokstak and see some Gravely porn. Thanks

    Thats a nice job on the bore and sleeve. I'm afraid I agree with Sparky -- you'll have to pull the shafts. Otherwise you'll just be wasting all that nice work you did on the hubs. PS have you seen the forums at smokstak.com? There's guys there that collect Gravely's, so they probably have all the blueprints and know-how. Its a great site for tractors and ag equipment, and old engine collectors.

    Not what you want to hear but the only way to do a good repair is to pull the axle. Once removed, the old keyway could be welded in and turned down flush, then a new keyway cut in another location.

    Is the taper you gave original on the axle or is it wear? If original, then a way to fix things might be to drill and put in a pin through the hub and axle. It would have to be a press fit so it wouldn't hammer itself out. Not a good way to fix it but there are not many decent alternatives without pulling the axle. A even more redneck repair would be to simply weld the hub to the axle.

    Gravely tractor axle repair ideas needed.

    I bought this Gravely 18G Professional last summer along with a sweeper attachment and I'm just now getting around to seeing what kind of a deal I got. First thing I noticed is it needs new tires front and rear. The engine has compression and spark and fuel (starting fluid) but won't start or even pop. The transmission and clutch seem to be free as is the mower deck so not any serious problems there.

    The main problem reared it's ugly head when I discovered the left rear wheel hub almost spinning freely on the axle. As you can see from the photos the hub keyway is pretty well hosed. But again not a big deal. I bored out the hub and sleeved it with the help of Locktite 680. Four stitch screws inboard and 4 outboard will go in next. But the axle!!! now that's a problem because I don't want to split the transmission case if I don't have to.

    Any ideas on making a respectable repair with the axle in place? The key is a woodruff about 1/4" thick. The taper is 0.100"/1.00". New axles are available but not sure of the price
