Facing a catastrophic failure on my kohler 6.5 genset.
this is a 1998, about 1100 hours on it.
over the winter, I had a oil seal on the motor side replaced due to a leak.
The tech took the stator and rotator assembly off to get the
shaft on the motor side out to bring back to the shop to
replace the seal. he said this is the only way to get to the seal.
He came back, put it all back together. In the spring, I launched and the genset ran like shit. called tech, he said to let it run for a little bit and see if it works itself out - winterized and all, made sense. We ran it for about 2 hours and ended up just shutting it down. he came back out, changed spark plugs with out even starting it and it ran good. For about 15 hours - then it happened. Dark smoke poured out of the generator side exhaust and smelled like rubber burning. shot out little pieces of burned plastic/rubber ... dead.
they came back out, took it apart and the spinning thing in the rotator assembly actually broke off.
Now the battle begins - the tech took it all apart, we think he did not put it back together correctly, they say it is just coincidence.
anyone ever have this happen to them?
whats your take on it - why would this part snap off if not because it
was put together wrong.
any one ever sue a tech before for a faulty repair?
