Well, what you are touching there is the timer for the injection pump. Behind it is a nice little bushing which should have been replaced ages ago. It is a very special little bronze bushing, but I can't find the correct name for it right now. My books are in the garage and it is raining hard all day. If you have a "Haynes Manual, you will find it pretty easy under the injection pump section.

Timer End Play
I went back and took a closer look at both the CD and book Service Manuals and found it listed as: End plan of intermediate sprocket shaft: 0.05-0.12mm.
In section 07.1-240 of the Service Manual.
I assume this measurement is take with the Timer installed on the Shaft and with no Timing Chain on it to interfere with the measurement.

I can't get your video to work but play in the intermediate shaft behind the timing device will kill your new vacuum pump very quickly. You have to dig deeper to save your engine.
