560 SEL saga continues...

Hi all,

Severe power loss after replacement of transmission. The flywheel has been removed to replace the rear seal.

Now we find that the timing, with vacuum removed from the EZL, stands at 20 degrees after top dead center. There are eight bolts holding the flywheel, that means each bolt represents 45 degrees. There are two full crank revolutions per engine cycle, 45/2 = 22.5 The timing is supposed to be 2 degrees BTDC with vacuum removed from the EZL, so it is about 22 degrees off.

My mechanic, though he is willing to revisit the driven plate (proper term for the flywheel on an auto tranny benz), said it is virtually impossible to install incorrectly, because of a notch that would not allow it to be properly bolted down unless lines up correctly. I've got tow mechanics insist that, yes, you can mismount a driven plate, and it needs to be checked.

Can you mismount it, or are we chasing a red herring?
