I am working on a Kubota L240, I know this is a grey market tractor, but the engine needs a rebuild. Can anyone help me in getting the right parts? I plan on replacing the pistons, but not sure of what to order or if I can find parts. Before i start tearing this tractor down I would like to know if I can find parts for the engine. It is an old tractor, but I think I could get many more years out of it.
