I am in the middle of replacing my upper chain guide rails on my 560. I have run into something that I wanted to get the board’s opinion on. For me to get to the pins for the upper rail on the driver’s side I need to remove the distributor. The removal is described in job number 07.5-510 which is missing on my CD. If anyone have that job description that would be great. However, looking at the distributor there is only one bolt holding the house to the gear so I am assuming that removing the house can be done after removing the bolt?
Now, unless you take great care to mark everything you run the chance of messing up the ignition so I would like to know at what degree the ignition should be set at? The above job number would properly tell you so please take pity on me and send it my way if you have it.
The 560SL timing ignition timing is established electronically. The position of the crankshaft is determined by a sensor device. The timing will "set" itself. The distributor therfore only distributes the spark to the various cylinders. No cam or reluctor, no wires other than high tension ones. The removal procedure I used was as follows: Remove cap and wires (label them first with tape) and rotate engine to TDC. If your valve camshaft cover is off on the passsenger side, look to see that both valves of cyl #1 are closed. If not, rotate the engine around one revolution again to TDC. Now mark the position of the distributor housing relative to the engine where is seats. I used a prick punch. Mark the location of the rotor to the distributor body with a permanent marker. Remove the bolt that holds the distributor in. Pull the distributor straight out. You will see the rotor rotate. Mark this location to the distributor with a permanent marker (use diferent mark for second position). Now you can get to the rail pins. Install the distributor with the rotor in the second position. You may need to re-install it a few times until the first marked position looks lined up when the prick punch marks align. Put the bolt back and tighten it. Be observant when you start. The distributor shaft "spiral gear" will cause the rotation when removed and reinstalled. If you are off a tooth, it should be apparent. Take it out, rotate it a bit and try again. The final timing should take care of itself.
