Basket pulley refurb
Posted: Fri Sep 14, 2018 2:20 pm
Just thought I'd share this. My 73 was making motor knocking sounds but ran fine for many years and sounded like coming from front pto. Got annoyed and started to tear into stuff and realized the basket pulley was flopping around. Tore it all loose and fortunately the crank was within a few thousands from being 1" but the hub on the basket pulley was 15 thousands over and obviously worn. I looked for used but only ones I saw or anyone priced to me was $60+ for used and who knows if they are worn. I remember they used to be a lot cheaper all over ebay. Anyway...
The hub is just pressed on with a flat spot to avoid spinning. After it was turned off in the lathe I bought a 1" hub (quicker and cheaper than turning out and broaching a 1" ID and keyway in my opinion). About 20 minutes on the lathe and quick flat spot on the milling machine I had a new hub made. I put it on an old crank and carefully welded to avoid the Inside Diameter warping from the heat. Got a longer key to grab some better material on the crank and reinstalled. This is way more rigid than the original press in. So far it's held up about 3 hours and noise free. Took about $10 and a couple hours total including reassembly but it's snug and true and quiet for the first time in years. Nice to hear the Kohler for once.
This wasn't my first choice to reinvent the wheel over just buying a good one but at $60 for used this was time well spent in my opinion. It would also be easy to drill and tap some holes in the hub for a pulley puller if you wanted.
