I have a questions and I'm sure someone has an answer. First of all my hydraulic pump seems to be making a ticking noise on my 2008 L5240 Kubota. It's quite loud in the cold weather in particular but I noticed it in the summer as well. In the fall I drained all the fluids and replaced all the filters. It didn't seem to make much difference to the hydraulic pump noise that I've been hearing. I'm worried it will be a big expense.
