Well everyone, I finally brought my tractor home today! For the record, I took it to the dealer in Mount Vernon, Wash. for a diagnosis. They did a compression check and found that cylinder 3 was 100 psi lower than the others. They took off the valve cover and saw no problems with the valve train, and the injectors looked fine too. At that point, the diagnosis and money I had already spent were equal to my deductible, so I called the insurance and made a claim. The dealer took off the head and found that piston 3 was not coming up as high as it should. Bent Rod!
They ordered the parts, and at that time I had to leave for New Mexico for a family emergency. They put in a new rod, piston+rings, bearings, pin, etc. as well as replacing the bent fender and loader control arm. They put about 40 hours of work into it, and then put it on the dyno for a breaking in period.
The insurance company was also great to deal with, and agreed to cover the parts I already had purchased as well as a small amount to cover my gasoline etc. for taking the tractor to the dealership.
The weather forecast was calling for rain for the foreseeable future, so since it was not raining earlier, I spent the evening mowing the field. Ran great!
And yes Junkman, the dealer did let me borrow a trailer for the day to bring it home. All I can say, is this is a class act dealership, and I am glad I chose them to do business with. For those who haven't heard, The Dealer Makes a Difference!
