The Clark's Garage write up is a little confusing but this is what I did.

I installed the roof, pushed the button so the motor rotated to the full up position. Then I pushed the down button to the locked position. With the roof removed I placed the lifting arms in place, counted the teeth and marked them as directed. I then installed the new gears and arms. With the ignition in position one I retracted the arms as if to remove the roof and the gears stripped when it was supposed to stop. Why is this happening?

For whatever it's worth, mine will always stip a gear if I wait for the thing to stop on its own. Instead, I just watch the arms retract until they're far back enough to remove the roof. Not proper, but less time consuming than tracking the problem, especially for as little as I remove the roof.

Have you checked the limit switches to make sure that they function properly?

Set the slip clutch (I loosen until it will no longer retract, then tighten just a hair).

It's my understanding that the limit switches only work for the raised and locked position. It seems to be doing this just fine.

For sunroof removal the arms act as a mechanical stop. Someone check my understanding of this please.

I'll give that a try. After I get another gear.

Mine is the same and I simply watch them go down and then stop hitting the button. Again easier than messing with it more than I have to. It works perfectly other than that. I just learned to live with it.

I'd *seriously* consider picking up a set of manual latches and doing away with the over engineering that Porsche did on this. The manual latches work about as fast as the motorized crap.

I took this straight off Clarks Garage. In the picture, when the cam is in position 1, it stops the arms from moving any more after they fully retract so you can take them out. I'd start there and check that limit switch. I've had my sunroom motor out so many times...my arms won't retract at all. My problem is a power issue with not enough getting to the relay to retract. Hopefully this helps!

At the moment I am tempted. But I have this "thing" about having everything work the way it was intended.

Thanks Darwin. I'll double check to make sure it is hitting position 1. But again, it is my understanding that doesn't stop the motor as my arms do retract all the way. So I assume it is making position 1 but it is a mechanical stop not an electrical one.

This is what I'm referring to:

I think that is the job of the clutch, when it detects splipage (meaning that it reached the mechanical stop) the motor stops.

That's how I understand it but I'm stripping gears also

+1!

I'm so much more happy with the manual latches. Although It's not as cool that I can't just hit a switch and watch it go up.

The switches do not stop the arms while they are retracting (to remove the roof). The slip clutch is supposed to slip and the motor will keep running untill you let go of the switch. The slip clutch does not need to be very tight, if it is, you will strip the gears. Replace the gears and adjust the slip clutch as per the proceedure in Clarks. I think the tourque setting for the nut is ridiculously low; like 4 in-lbs (not ft-lbs)
Basicly, just loosen it untill it always slips, then tighten it just enough to stop slipping when raising the roof, then just a little bit more (like 1/4 turn). Once proprly adjusted the gears should be good for many years...

I had the same problem untill I adjusted the clutch, many years of worry free operation since.

edit - Never mind.

Still struggling. Now on my second set of gears.
