I was hooking up the 4440 to the planter and noticed the seal around the shaft that runs from the harmonic balancer to the hydraulic pump was leaking on the hydraulic pump. I read that you have to pull the pump off the fix it but that is the only spot leaking. I also saw that you have to pull the fuel tank and radiator to get the pump off. Does anyone have any tricks or tips that might be easier?
