This Video: R107 - Fuel Distributor 0-Ring Replacement
I am documenting every part of this vehicle as I put it back together. The idea is to end up with the best documented 560SL rebuilds on the Internet.
In this video I pick up where I left off yesterday and replace the two sealing rings (o-rings) that are located on the bottom of the fuel distributor. The Mercedes-Benz documentation calls this procedure "renewing sealing ring for control piston", but I'm titling this video Fuel Distributor 0-Ring Replacement because it makes more sense to me.
I want everyone who visits my channel to know about a friend of mine. His name is Tasos and his videos inspire me to be more like him. You can find his YouTube channel at:

For this job you need a fairly accurate caliper. I recently purchased the Kynup Digital Caliper Tool and I really like it. It seems to be quite accurate as I have tested it with a caliper:

In this video I also used an ultrasonic cleaner. I really like the one I have. The one I have is a 6L/1.7 gallon with strong heater and digital timer. This one has a 300 watt heater and 180 watts for ultrasonic cleaning. You will see in this video that it is very effective:

You MUST keep things clean! Don't use just any ordinary paper towel. Paper towels will leave small fibers behind. What I use are these Lint Free Cleanroom Wipes:

You will also need some common tools like a 12mm and 17mm open end to remove the injector lines and a screwdriver to remove the fuel distributor. There are no torque specifications for this job.
This video is very detailed and is intended for the absolute beginner (ME). This is how I did things. If you see a problem, let me and the world know by leaving a comment.
Disclosure: I have never pulled an engine before and I have never rebuilt one either. This video series is documenting an inexperienced old guy tore apart his 1987 560SL.
