1964 ford 4000 industrial hydraulic pump fix - HELP

CT Mathis	Just purchased a sweet 1964 industrial 4000 and after 20 minutes of bush hogging last night I realized that the pump lost all of its power. The fluid is full and clean and I understand this is fairly common with older tractors, although this one only has 1500 hours. I am a little upset because the seller failed to mention this to me and only after the cash changed hands did I realize this. I have seen rebuild kits for this model, # CKPN600A, and was wondering if I can do this myself or is it absolutely MANDATORY that a ford mechanic rebuild it. I have priced these rebuilt for $600 and mine to be rebuilt for $300-400. PLEASE give me some good news and helpful advice.
Leon	First off, I think you have the wrong kit. CCPN600AB is the number for 1953-1964 tractors. If you tractor has a 3 cylinder engine then you have the right kit but the wrong year. It would be a 1965. If you have some mechanical knowledge you could rebuild this yourself. The only thing you will have difficulty with is replacing the valve seats, it requires a special driver tool. There may be other parts you need like the wobble shaft/plate or the bearing. You won't know this until you pull it apart. -Leon
Leon	Oh yeah, don't forget to put all the pistons back in the hole you got them from.
CT Mathis	Thanks, you are right. I have a 4 cyl gasser that has another p/n for the rebuild kit. I found the kit for around $30 on a couple of websights, does this sound correct? Will I definatively need the seat tool?
Leon	Yes, price sounds right. No, the only reason you would have to replace the seats is if they have excessive wear.
