914World.com _ 914World Garage _ Targa Top Failed Latch
Posted by: earossi Sep 9 2015, 08:44 PM
In attempting to install the top on my car, I encountered resistance from the new front seal that goes across the windshield. The seal, being new, has not taken a set, so it took a lot of force attempting to "pull" the top forward into the seal. So much force that I managed to break one of the pot metal latches on one side, and the stepped pivot screw on the other latch sheared off at the threads.
The top was latched in place when I picked up the car, but I am obviously doing something wrong.
So, I have several questions.
First, is where to source new latches and the stepped pivot screw that I managed to break. I assume that I can source them used by placing an ad in the WTB parts section of classified; but, it would be nice to install new parts, if they can be sourced.
Second, any suggestions on why I ran into the latching issue? When I placed the top on the car, I indexed the front lip into the windshield seal, and then attempted to pull it into place with the latches, until the latches failed. Obviously, something is not correct.

Your old seal had taken a set over the years and lost it's elasticity.
The new seal is probably "puffier" as it is new.
On the latches there are adjustment studs for such an occurrence. You would loosen the nuts and let the latch catch slide a bit.
Boiled down .... Old seal = thin and New seal = thicker.
You should be able to push the top into place in the seal. You could try some lube on the seal (soapy water).
That's my take.

Great suggestion. I'll use some dish soap to see if the top will slide into place, as soon as I locate a replacement latch.

Your latches are pot-metal ?,I thought they were pressed steel.
You will need to relax the latchs with a new seal and adjust until the roof panel is level with the windscreen frame when clamped down.
Sorry to ask but is the seal fitted properly ?

Puffier?

The new seal that is available seems to be fatter than the original one. It also could be the lower one is too fat or incorrectly installed. (upside-down?) I have this same issue and therefore, I rarely take my targa top off. It's too much of a hassle putting it back on. I wish it wasn't this way, but it is.
There is some adjustment in the front latches if that is any help. Used ones are not too hard to source, either.

There's no pot metal on a Porsche! Is there??

Ha! Surely you jest! Most of the parts that I break are pot metal. Prior to the top latch, I managed to break one of the pot metal loops that attach to the end of the seat adjusters. There is pot metal all over the car!

Thanks for your offer Bruce. I was able to source the parts locally.

I had a similar problem, without the broken latch, thankfully. The new seals were much fatter than the ancient ones I replaced. I solved it by cranking the latches down and leaving the top on for several days while it baked in the sun. First time I tried to remove the top, the upper seal tried to come with it! So, pulled the seal out manually, glued the hell out of it, and repeated the whole process again. Now it's snug, and no seals are misbehaving. Hope that helps!

No, it's called Zemac in third world countries .... aluminum zinc alloy. The only pot here is generally green.

I too had the same problem; to make the top slide in/out easier, I dust the seal with baby powder 2x a year..
