Restoring BIG Excavator Arm & Bucket! | PART 2 | Making & Installing Thrust Plates

We’re completing restoring the thrust faces of the big ZX690 Excavator stick and bucket! Part 1 was all about machining down the worn thrust faces with the WS2 Plus, now we’re tackling making and installing new thrust places. We start with flame cutting the high tensile steel to a rough profile, then it’s on to our lathe to machine the plates to exact dimensions. We can’t forget about the O-ring, so we’ll also machine a recess for it to sit securely. Next up are the replacement bushings for the bucket. We need to machine them to the right size before giving them a special cryogenic treatment – a fancy way of saying a dip in liquid nitrogen to ensure a snug fit when we install them in the bucket. ❄️ Finally, the moment of truth! We’ll carefully fit and weld the new thrust plates onto the excavator attachment, giving it a new lease on life. This video showcases the meticulous work that goes into a successful repair. It’s all about the details that get these machines back in
