It's beginning to look that way. I received a response from Kioti customer service earlier today. While I can't re-publish a private email here verbatim, they're basically saying that they won't make a determination to help me out until after the tractor goes back to the dealer. Only then will they make a decision about whether or not to provide any out-of-warranty assistance. So despite management having reviewed several high-resolution photos (bigger and better than what I posted here), there's no up-front commitment at this point. The owner of the dealership, his service manager and several folks on this forum have stated that based on the photographic evidence alone, this issue is clearly a manufacturing or assembly defect and not operator error.
Without an up-front commitment, I'm reluctant to take the tractor back to the dealer again. I had hoped that Kioti would have shown more interest in this situation, but they are not giving me much of an incentive to to do it their way. I haven't replied yet, but my thoughts are basically, if they really want to examine and study the remains of this piston for failure analysis, then they need to assure me now -- before I bring the tractor back to the dealer for the second time -- that I won't incur any further cost beyond what I've already paid (financially and in down time) in order to provide them with it.
Honestly I don't think I'm being unreasonable here, but I'm open to your constructive criticism. There may be a call to the dealer about this; I'm not sure yet. Anyway I need to get hard copies of all the service work they've done for me in the past. It's been meticulous and it'll help me sell.
Meanwhile... Plan B. I had a chat today with my friendly neighborhood diesel mechanic, whom I have known and given business to for 13 years, about what it would take to do the piston replacement. His blue-sky, no-surprises estimate is around $750 to $1000 for labor, plus parts, which I'm figuring to be in the $350 range (cylinder head gasket, piston, rings). For the one piston. And I can afford that. If it's economically feasible, then I'll do all three. I would feel so much better about selling it that way, it would be so much easier and I'd sleep a lot better with all three pistons replaced. It's just a matter of cost. If there are folks here who know, I might be running part numbers by you to make sure I'm ordering the right stuff. Have you seen a CK series parts list? I have and it's **** confusing.
I would have been *happy* to appear in that goofy commercial.
