I am hoping someone can offer knowledge. I bought a 73 MF40 industrial at a yard sale, had to hire a crane to get it loaded. It hadn't ran since about 1980. Amazingly with cleaning the tank and few other little things it fired right up. Now the problem is the hydraulic steering. Neither wheel would turn. After rebuilding the pump it turns out the left side Pivot pin is stuck, the right will turn with the tractors wheels off of the ground and tie rod and cylinder removed by hand easily. The left is just stuck solid. I tried pumping grease in until the pressure was trying to put it back in the gun. Put a chain to the bucket, around the front, to the back of the tire. the chain was so tight I could play notes. Put a 48" pipe wrench, feet against a wall, body off of the ground. Tried heating the outside until it was hot. Took the tie rod part off of the top so it was just the pin, and spent about 20 minutes going at it with a 12lb sledge. Never moved even 1/100 of an inch. I have never seen anything stuck like this. Any help/tricks at all will be greatly appreciated.
