I got an older national 556A boom truck that has a leaking boom scope cyl. I have the factory manual for the crane and procedure for pulling the cyls just wondering if theres anything i should KNOW before i start in on it? As always the procedure makes it sound so easy.
its a 3 stage hyd with one single boom mode, fully proportional.
