In the spring the day after tilling, the K482 in one of my 1886's seized up. I found an engine that was described as having a new low hour short block that was installed at a dealer. The engine turns over and has good compression and appears to be in good shape. I didn't like the black engine tins so i bought paint and painted the tins. Afterwards, I thought that freshly painted engine would look bad in the rusty tractor, so I bought more paint. In the process of cleaning the frame up, I decided that the hydrostatic unit and rear need re- sealed, so I bought new o-rings, seals ect. After that I decided to replace the front axle pin and bushings to tighten the steering a bit. Then I realized that the spindle bearings and bushings. After all of that, I put the engine in and made all new wiring harness for it and put an oil pressure guage on it. Finally this past Saturday, I got to start it and was very disappointed as the rear cylinder has a knock. I really don't understand what went wrong since the oil pressure guage showed 45 psi! Now I'm not sure if I want to try to rebuild one of the k482's or just re-power it with a new engine. I suspect that it would need at least 1 rod and piston but that could be real expensive if I could find them. Should I re-power it or rebuild it? Does anyone know of an engine builder in the York Pa area that could do this rebuild? Does anyone know where I can get OE or aftermarket parts/part numbers for these? Any help is appreciated. I have a nice looking tractor with a lame engine.
