Hey guys.... I've spent the last hour sorting through the abundance of sunroof posts trying to find an answer with no luck.

I have an early '86 951 sunroof setup (without the white gears) and the sunroof just stopped working. After many hours diagnosing the problem, it appears that my problem is with the the motor clutch tension.

The gear on the motor spins freely when removed from the assembly, but when installed, the motor spins and the gear won't. I found articles about adjusting the clutch for later model cars (with the large 21mm adjustment nuts), but nothing about the earlier models.

My car has just one pin and a 10mm nut on the back of the motor. I've had the pin tightened and loosened with no difference. Are the early models even adjustable?

Judging by the overwhelming response, it looks like Porsche didn't use this configuration in too many cars. Did the early 944s (pre-85) use a similar setup? Thanks.

I'd help you, but I'm only familiar with the 87+ sunroof, so I don't want to give you any mis-information.

Thanks for the posts guys. I've looked over the links and unfortunately both of them address adjusting the slip clutch on later style cars with the 13mm locking nut. The early 86 units have a different setup that doesn't appear to have much adjustment at all.

I'm gonna go through the whole setup again this weekend and see if I can find a way to get it working. I'll let everyone know what I find out.

Thanks, please do.

I have an same system, but with an one way action (not lifting the arms).
Will be trying to solve that in the weekend.
Clutch is working, can measure the extention of the center bolt to the lock nut if required.
