A few weeks ago at work, we changed out a power assembly on one of our locomotives. I took the Go-Pro with me and set it up on time lapse to get some footage.

We only changed out a short pack – the head, liner and piston. The original carrier and connecting rod stayed. Check out the above video, it takes you thought almost the whole process other then setting the valves and injector at the end. Thanks to my friend Chris for putting my footage together into something presentable!
