A little Machinist advice please

Is that a JS or JA 65 series mower? If so, just get rid of it. Deere's venture into mass marketing, and they failed with those too.

The JX/JE series and 14SB mowers, however, have been awesome, just expensive. I buy them from time to time and give them to folks who need them. I used to make a good bit of money on them, because a lot of people were still paying top dollar for clean ones. That kind of sunsetted and I generally just give them away now. Always get to work on them, though...general servicing is about all they ever need. Blade here and there and an occasional blade brake clutch on the rougher used ones. I still have two of them, I keep the bad one and my mom is getting the other one which looks cuts runs like a brand new one.

JX 75 - good mower with a Kawasaki engine, aluminium deck (good and bad). Just this pulley issue.

make sure the nut isn't bottoming out on the shoulder of the shaft. If it does, the pulley won't be tightened up fully. and destroys the pulley. We always used an axle washer under the pulley to help tighten it up.

So, my question - any hope of fixing this? Alas I did not buy that metal lathe 10 years ago so I am limited in my fabrication abilities but I can get pretty creative. Any hope here or just chin up and buy a new one?

How are you at welding?

Princess Auto has a line of weld-on pulleys. You match the appropriately sized hub with the required diameter/width of pulley and weld the two together. The hub is indexed to ensure concentricity.

There IS some scoring on the bottom of the hub - I think your on to something by gum. Noted and now part of a plan.

I did have a look at Princess but must not have looked closely enough. My welding is a little artistic (not in a good way) but does stick. I will look again.

Thanks gents.

IIRC, the hub "series" refers to the index diameter. It needs to match the hole diameter of the chosen pulley. I believe all those pulleys take the W series hubs I linked to. They have other series hubs as well, but I think those are for the weld-on sprockets .

Thanks Torch - looks like a real possibility if I kind find a 10 mm hub - and I think PoTreeBoy listed one earlier - if it fits.

If you can't find a 10mm one (and you are sure it's 10mm) send me a PM.

That's what I was 'shade-treeing' in post 10. I couldn't find a 10 mm weld hub.
