I have read Kubota had a timing gear issue with this model. I just bent all the push rods and pretty much destroyed the cam , crank and idler gears I am new to the diesel tractor world just wondering what would cause this to happen. Kubota was fixing the problem for 10 years according to the info I read . Does anyone know what this problem was. Don't wanna replace all this for it to turn right around and destroy it too. Thanks for any advice
