Current snag; hatch will not open on my 1986 944. Sounds like manually opening it is suppose to solve the problem, yet after tht and trying some persuasion with a rubber mallet the problem still stands. I can pull the black receiver down on the passenger side but doesn't release the pin and on driver side tht receiver isn't going to move down. I took off the hardware on em too... So what should I try now?

Thanks!

If the receivers are removed soak them in some solvent to dissolve the old sticky grease then re lube . Make sure they snap back closed internally .
clean the latch pins. Then lightly snug the receivers back on the car so they can be positioned sight down the pin right before it enters the receiver and re position aligning the receivers with pins. don't over tighten the receivers if they get to tight they can bind up and won't open. How is your hatch at the frame/hinge area if its separating at the hinges that can be an issue as well.

Donor car has new pins so ill be sure to do that, yet gotta get hatch off first

Edtay

Bump. Tried wedging a prybar between the black receiver and the body, tried using a screwdriver and a hammer to break the receiver, and removed all hardware i can see but problem is still here

Not sure I understand the problem.

Are you saying that those little sphinchter-like things that grab the hatch pins are frozen shut?

Did this happen all of the sudden?

Have you poked around on the clark's garage website? They might have some advice or a how-to there.

Ive been searching around but its sounds like manually releasing at the interior side of the lock will free the pins and the hatch would open. All Clarks has is "Repairing a Squeaking or Rattling Rear Hatch" and "Rear Hatch Strut Replacement" for the rear hatch. The car has been dead for a few months so cant really comment on how quick it happened. Tomorrow I can climb back and record what the issue is if that would help show the problem. But you got the problem spot correct.

The spot that is the issue on the hatch is #26 in the PET Diagram. I removed both 10mm nuts on that piece. Is there a difference between loosening em and removing em?

J Berk

I don't know. Only time I had an issue with these (which was not too long ago and I posted about it here)...one of the 'sphinchters' jammed in the closed position while my hatch was opened.

It would therefore not allow my hatch to close.

I soaked it with Wd-40...and losened those nuts on the bottom.

After about an hour of soaking it became free and I only snugged up the nuts.

Gave it a good bath in spray teflon and it's been fine since.

Edtay

You just loosened the nuts? I may replace those and see if i can just loosen em to do the trick. The lock seems to work and "open" the receivers. Yet the hatch is still suck... I have a parts car in the garage that has a good hatch so im not worried abt breaking parts

Mhart

I've had my hatch stuck shut by the hatch seal before. Sprayed some WD-40 aroud the seal externally and let it set for a hour or so and it broke loose.

Edtay

So I rebolted those 10mm nuts back on then loosened them all slightly, soaked both the hatch seal (from the outside) and the receivers/pin releases in WD-40 but the hatch will still not budge...

J Berk

So the little sphincter things open but the hatch is still stuck?

If I am not mistaken...the way these work is that there is a plate that looks like 1/2 a plate-washer...eg: semi-circular hole in it...that slides back and forth to create the opening and then latch the pins..believe it is # 25 in the parts diagram.

When you took off the nuts completely...did the mechanism come apart exposing this? If not...don't take it apart because I suspect it will be a PIA to put back together....but it would be nice to know if both sides of each plate-washer are free.

With mine...on the driver's side of the car, one side of this plate was free to move and the other was not...causing the pin to not have enough room to go through the latch.

I played with tightness on these nuts and got them just right so both sides of each plate move.

If those plates are free...then I am not sure whatelse other than perhaps corrosion could be keeping your hatch closed. Silly question...but there is nothing in the crease between the top of the hatch and roof is there ??

Edtay

They seem like they open. When the 10mm are not installed, the black thing doesn't fall apart... I will break it if need be. I'm swapping hatches (donor car has tinted glass). Nothing seems to be in tht space between body and pivot point for the hatch.

Edtay

Problem solved: BFH and screwdriver to the passenger side (destroyed the receiver) and then jammed a screwdriver into the driver side pin hole/receiver which pushed the clasp/s back. Hatch has been replaced and everything is almost back to normal.
