Mine had a hard collar of rust between the shaft & the thick washer you're struggling with. I soaked it for days with Power Blaster & tapped it 1000 times with a large brass hammer. Digging in there with a small wire brush & a dental pick helped too.Dummy question but I got the nut off but what appears to be a washer under the nut apparently is not a washer as it will not come off. How is it removed?
I'm headed to Uruguay on Monday. I'll be working near La Paloma for a couple weeks. I'm installing Wind Turbines on the http://www.nuevomanantial.com/ ranch.Thanks to all. I finally had to heat the washer with a torch and wedge it off starting with a thin blade putty knife followed by two cold chisels under the washer to act as wedges. I am sure it never was removed before as the saw blade looks like it was never used. Mine is also red but may have been repainted. The saw is now packed and ready to go with me to Uruguay South America where it will be used with the two Gravelys I have there to cut saplings. The Gravelys have been real work horses on the farm.
