I'm not the uploader of the video, but I am an engineer at a company that trains the people who do the work seen on the video, so I will try and answer some of the questions the commenters keep asking: Q. Why was it changed? A. When an engine reaches a point where it needs some significant maintenance work (such as an overhaul), it makes more sense to swap it for a new engine than doing the work with the engine on-wing. That way, after just a 6-hour engine-swap, the plane is ready to resume flying and earning revenue, and meanwhile you can carry out the repair work on the engine comfortably in the hangar over a period of several weeks (or ship out parts to have the work done in specialist facilities). Q. Just 6 hours? It would take much longer to change a car engine! A. Aircraft engines are designed to be swapped. They are exposed on all sides (except the top in this case) and mounted to the structure by very few bolts (typically on business jets it's just 2 mounts - forward and aft. May be more on the 777 but at any rate not much mechanical complexity). All the connections between engine and aircraft (fuel, electrical power, bleed air, hydraulic power and electrical control and sensor signals) pass through a firewall in the engine pylon where they are easily accessible for disconnection. Q. How fast does it spin at takeoff? A. Assuming the engines in the video are Rolls Royce Trent 800s (93,400 lb. max thrust), you're looking at a 3-spool engine (N1, N2 and N3). The RPM at full power would be: - 3,000 rpm for the low pressure system (including the big fan at the front) [N1] - 7,500 rpm for the intermediate pressure compressors and turbines [N2] - 10,000 rpm for the high pressure compressors and turbines [N3]

+LMF5000 Those must be some strong mounts and bolts being able to hold 15000 pounds and all the thrust. On the DC10 the anchor point looks weak and as if the motor will break off at any moment.
@LMF5000

+dbza They are just strong enough to take the weight of the engine, the thrust loads, extra loads induced by maneuvers or turbulence, and a good safety margin on top of all that. The reason they make the mounts relatively weak (actually, the bolts are the weak point - they are deliberately designed to shear at a pre-determined force) is so that in an emergency where the engine is impacted hard, the forces will rip the engines cleanly off the wings rather than putting that huge stress on the entire wing structure and potentially breaking something more important.

+gearhead996 Quite unlikely. Since a plane that's been flying for a few years will have two engines with very different histories (due to the factors mentioned in my answers above), they will have a very different number of flight hours each, so they'll probably be taken off the wings one at a time when their individual time is up.

The F-100 would be taken quite a distance to a run up pad for testing because we had an afterburner to check out. Even though it was an old engine, the F-100 had to be restrained with cables with the thrust that the engine could produce in afterburner.

indeed it is. For those who don't understand how powerful balance is, search out (on here) "Rolls Royce Blade-off Testing" basically, they take a turbofan, just like this, and blow off one of the turbine blades to test how the engine copes the initial shock and unbalanced forces... it's absolutely unbelievable!! moreso how the engine can withstand it!!
