Andy, there is a reason your company sends them out. They are an absolute bear. If this is the telescoping type cylinder the gland nuts are brass and have very little tolerance for pressure. If you use the typical chain or spanner type wrenches (or even worse a hammer and punch) you will deform them and then you will have the cylinder back out again going to the hydraulic shop. I am sure you are a very competent tech but this is a fight you will loose 8 out of 10 times unless you do them everyday like a hydraulic shop. Just trying to help a brother out when its hot as **** out.
