Flywheel Orientation

The one's I fiddled with looked the same, but weren't. There was a guy on here a while back trying to force in a bolt....he went kinda silent after a couple of posts about the "pattern". So if you've checked with just your eyeball, you might not see a pattern. If there is no pattern, and no other mark, index, tab, slot etc, then it shouldn't matter how it goes on.
Stand by, you may get another reply, there have been some rebuilds of this engine discussed recently.

While I have been known to question the accuracy of Haynes manuals, here's what mine says: (I've really got to find either a shop manual or a Chilton's lol)
Removal:
"Carefully inspect the flywheel and pressure plate for indexing marks. The marks are usually an X, an O or a white letter. If they cannot be found, scribe marks yourself so the pressure plate and the flywheel will be in the same alignment during installation."
Installation:
"Position the clutch disc and pressure plate against the flywheel with the clutch held in place with an alignment tool. Make sure it's installed properly (most replacement clutch plates will be marked "flywheel side" or something similar - if not marked, install the clutch disc with the flat side of the hub toward the flywheel). Note: On 1997 and later models, the pressure plate may have an adjustment ring that must be adjusted before installation. Use the following procedure (if equipped):
a) Use a suitable press to press all the fingers on the pressure plate down.
b) There is an adjustment ring integrated within the pressure plate that can be rotated - move it to the extreme counterclockwise position until the springs on the adjuster ring are compressed fully.
c) Hold the adjuster ring in position while releasing the tension on the pressure plate fingers.
d) The clutch pressure plate is now adjusted and ready for installation."
The installation procedure does not mention anything about indexing marks - only the removal procedure does and, I assume, that's to keep the original clutch disc and pressure plate lined up to each other. The installation procedure in the manual assumes you're either replacing the clutch disc or the pressure plate and, since it doesn't mention anything about indexing the two, I would assume it's not too overly concerned about it... These procedures seem pretty "generic" to me...
A lot of assumptions here lol, but I hope it helps...
The last time I replaced a clutch was in 1991 on an '84 Mazda GLC so, don't take anything I say as gospel lol...

That is a harmonic balancer. While there may be some basic balance work done by the harmonic "balancer", it's main function is to absorb and dampen vibration in the crank.

Also, I read on the Sachs site that that is the case and the reason for the adjuster ring is it self adjusts as disk wears so pedal effort does not increase with wear. I don't know about you but I'll take the simpler old design and increasing pedal effort. Keep it simple so there is less to go wrong.
