I'm a machinist and have worked in job shops for about 25 yrs. There's not too many things that I've seen that couldn't be repaired unless they were completely destroyed. With that said, I have a 1965 John Deere 2010 that lost it's pto. After tearing it down, I found out that the pin in the output shaft had sheared and busted the shaft. The hydraulics on the tractor get weak after the fluid gets hot, so while I have it apart, I decided to take a look at the pump. After taking the pump apart, I have decided that it can be rebuilt with a little work. I am debating on rebuilding it so it has replacement parts in it for the future. My main question is, would it be worth it? Is the hydraulics the biggest problem with the 2010??
