We're on a mission to rescue this cylinder and save the customer a hefty chunk of coin. This hydraulic cylinder off Caterpillar’s biggest motor grader has a seized gland and the customer has tried everything to break its stubborn grip, but nothing’s budging. Join us on a rescue mission as we turn detective, machinist, and welder all in a day! First, we start with machining a custom locking pin to get the cylinder setup in the lathe. Then we machine out the weld and remove the cylinder end before setting the cylinder up in the hydraulic press and removing the rod and damaged gland seals. Then, it's time for the main event: removing that stubborn gland without damaging the rest of the cylinder. This might sound straightforward, but there's a fine line between saving the day and creating a whole new problem. Unfortunately, the gland is seized solid and that means we have to carefully machine it out in the lathe, all the while keeping the cylinder barrel and threads in good shape. Once the gland is removed it’s time for welding the barrel end back in place, stronger than before. In just a half a day’s work, we’ll save the customer a lot of cash compared to a whole new cylinder – a winwin for everyone!
