I have been working on some of this Ford 5000 I recently purchased. I am working on the hydraulics. The lift arms didn't work so I removed thed the top on the hydraulics and found one of bolt holes on the lift cylinder itself was cracked. Is this something that could prevent the hydraulics from working properly or is it something that's not that big of deal and should be fine? The relief valve that is screwed into the end of the cylinder housing was stuck closed and I'm thinking this is why the lift didn't work. This crack is located by the relief valve. Any opinions greatly appreciated.
