Export threadOf course a diesel engine does make some tapping type noise, but if yours is that loud, I'm like you--it sure doesn't sound normal to me either. I'd insist the the dealer check it out. You can insist on speaking to the main man over Kubota and he WILL take care of it. I know from an experience my cousin had with his Kubota zero turn mower. The head guy visited the dealership where his mower was in the shop, and after they delivered it back to my cousin, it was finally fixed. He simply called the regional manager for Kabota and told them the problem he was having and that his mower had been in the shop more than at his house and he either wanted it fixed right or his money back. As I said, the manager took care of the problem.
Has it always made the noise or is it something that just started? Does it do it all the time or just at certain rpm?
hear this noise thoughout rpm range.could it be valve lash or injector pump.this noise run 1/2 time,likes its in the top-end of engine.
Is it a rolling rattle or is it a tapping sound
it sounds like a loud tapping:confused2:
