kckadi Posted April 17, 2019 Share Posted April 17, 2019 Hopefully someone can help, I recently picked up an 800 gal steam jacketed 1961 Hamilton Kettle with counter rotating mixers for a mash tun. It was a good buy and I knew it would require work. I need to rebuild the lower half of the gearbox which requires removing the two inline counter rotating mixer blades. But I can't seem to get the mixer shaft out of the lower gear box coupling. I removed the drive pin from the center shaft and the keyway set screw for the out shaft but the outer shaft(it has a hollow outer shaft turning one direction and a solid inner shaft rotating the other way) will not budge out of the outside shaft coupling. I really need a drawing or manual on the gear box before I put a hydraulic collar on it. I'm worried I missed something and will end up breaking$$$$$ the damm thing. I find very little about Hamiliton online. Hamilton is no longer a separate company and I heard it was bought by someone else(Trinity industries?) Does anyone know anything about Hamiliton kettles or perhaps knows someone who does? I am an engineer with 30+ yrs experience with mechanical systems so I have tried all the basic stuff (heat, penetrating oil, vibration, etc). It looks to me like a simple splined/keyed shaft and it could very well be that it is just seized in the coupling from age but I want to be sure before I go nuclear on it. I'm hoping this bargain kettle doesn't kill my $$$$ account! Thanks -- Kevin Link to comment Share on other sites More sharing options...
kckadi Posted April 19, 2019 Author Share Posted April 19, 2019 Got my issues squared away. For anyone else with a Hamilton kettle you need to disassemble the gear box as the outer agitator/sweeparm shaft is bolted and keyed directly the bottom bevel/differential gear. Only online resources I could find for help was Enerfab in Ohio, http://enerfabparts.com/ . They were very helpful and actually sent me CAD drawings of the gearbox which I've attached for anyone else who may need them. Also helpful was https://kettles.com/product-category/kettles/ in Georgia who were extremely helpful with phone advice.
