I recently had my 4010 clutch replaced. After I got it back, the hydraulic pump leaked. I already removed the wide front and looked for obvious things. It looks like the main shaft is just leaking from all around. I tried asking the mechanic, whom has been working on JD's for over 40 yrs, but he is off work with back pains. Does anyone know if, or how, the clutch work could have affected the pump? Linkages? Lines removed? Anything else? It could be a coincidence, but before I replace the pump, I was just wondering if anyone knew anything about these pumps. Thanks................ David
