Hi everyone. Well, I could not shift anymore and I looked into my clutch and the throwout bearing had split. I ordered a new one from Kubota, split the tractor, replaced the old one, closed it up and it lasted for a few minutes. Looked again and the bearing had gone through the diaphragm and gor stuck on the other side. I split it abgain, removed the whoe clutch assembly and realized that some provious owner had adaptated some diaphragm spring and left the central hole too wide. He had bent the teeth of who knows what spring diaphragm to more or less fit the throwout bearing, but eventually it gave. I did not know that was even possible...
Now I am waiting to replace the whole assembly with an original one. Here is a pic of what I pulled out. Has anyone seen anything like this before? Any thoughts?
