I'll take that back -- it's the retaining bolt for the drive hub being removed with the red "shreds" under the washer representing some RTV used to seal the splines.
I've always liked this stuff though it looks like an incredibly tedious amount of effort to produce it. Here is one that is an hour and a half of stop motion animation while a guy does a complete restoration on an old Range Rover. Imagine doing this in the old days with a film camera.
I've taken apart dozens of these engines.. not a single one has ever had the ability to have the diff cover removed with the engine mounted. They had to pull the studs and then install after the cover is on. For a number of builds I offered the owners the option of bolts to replace the studs, popular option for the track guys.
Creates more questions than it answers. What treatment done to the aluminum? How are the yellow zinc pieces managed? New or re-plated? Where?
Like are they tied together in a chain, or in little baskets? How much and where? Turnaround time; how long do the components need to be apart before they are returned? etc etc.
Look for a shop that does barrel zinc if you can. Its easier than racking and wiring individual small parts
Fantastic reference video!!! Really brings the workshop manual and parts diagrams to life. Particularly liked seeing the cam drive bearings and seals, and shift shaft seals which I will be tackling soon.
