I have a JCB 1400B backhoe. The hydraulic ram that operates the boom is leaking badly and I need to replace the seals. I've tried to remove the roll pin at the rear of the cylinder but it won't move. I used a 1 1/2" steel dowel against it and beat on it with a sledge until the dowel started to mushroom. Didn't move. I heated up the other side and beat on it from that while it was hot and again when it cooled too but it still won't move. The rod end pin moves easily and the ram moves about an eighth of an inch horizontally on this pin but the pin doesn't. It's inside the boom and the only way to get to the seals is to remove the ram from the boom. I've burned out about 1/2" on one side where the security bolt holds it because it had been brazed in one spot. I don't see any sign of brazing on the other side. I ground out all the slag with a die grinder so now I can see a clear line of the pin. I beat on it some more but it still doesn't move. It's 50mm (2") and tool steel I suspect by the sparks when grinding. I also called around to companies that do hydraulic cylinder repair to see if anyone had a mobile hydraulic press service but got no response.
