hi

if anyone knows the exact size in mm of the triple square (a.k.a.
cheesehead?) socket required to remove the screws on the hatch pin
housing unit, please let me know.

thanks!

it's the same, I am pretty sure, as the axle - easist thing to do is get a
set from Kragen - for about $14 you get four of the drivers, one fits the
axle, if the other is different, it's in the set. Beware that they can
break, that area is subject to corrosion.

by the way, if anyone needs it, I have a rear hatch frame (really really
cheap), and a complete rear hatch with good glass, etc (not so cheap)

For a simple English guy:

What is the flap latch housing?

What does triple square mean? Is it what we call hexagonal in the UK?

If this is relevant the transmission oil level plug is 17mm

that's what it says in the catalog(s) - its surrounds the mount which
the hatchback pins screw into ... i can't tell what the rest is from
the catalog(s), i was hoping to remove it for a better look.

> What does triple square mean?

draw a square - four points, right? - ok, now put another one.. and
another... :^)

> Is it what we call hexagonal in the UK?

the internet says they are called "cheeseheads" - /sarcasm on/ you can
get lots of those in Wisconsin in the fall - however, they usually
can't be found after January. /sarcasm off/

> If this is relevant the transmission oil level plug is 17mm

i'll post the measurement when i confirm it - which the internet
suprisingly does NOT have any information about.

It's called a triple square or XZN fastener, and the size is probably M6
(from memory). In the US, Baum tools will sell you a set of Stahlwille XZN
sockets for not a lots of money.

indeed it is! this is cool, did you see the wikipedia *series* on
screw drive types?

http://en.wikipedia.org/wiki/Screw

no mention of "cheesehead" there...

"Cheesehead" refers to the shape of the head of the screw, rather than the
socket / bit type needed to turn it.

your memory is good - "M6" must mean "6mm", since that is the size of
the triple square i used to remove the screws - part 12 in the Porsche
catalog (via Pelican) sec. 8.803, illustration 803-05 (p.257,
25.08.2006), part 999 219 011 07, "countersunk-head screw, M 6 X 16".

note : i have a 1987 944 n.a. i read the reference above, dug through
pelican, and i'm stuck - what are these screws going into? is it the
spoiler? the rim that the glass sits in? the drawing seems ambiguous
at best, the housing is not to be seen. i looked at the other model
years' catalog too, seems mostly the same.

some details :

i see a rusted broken-off hatch pin inside yet ANOTHER housing of some
sort which i am loathe to identify using the above mentioned catalog.
the triple square screws simply fit through the holes on the "flap
latch housing", or "housing" in the catalog (this part is drawn once,
but has four listings as "10" with different numbers) that i just
removed. after that, they screw into the threaded socket in the
housing i can't identify. the hatch pin also (apparenty) screws into
this housing (hard to be certain b/c is rusted/broken).

any pointers appreciated

the hatch pin brackets screw into a metal frame to which the glass of the
hatch is screwed. The top of the frame connects to the hinges. The rubber
wing and surround screws to the frame, and some trim along the top is
clipped to the frame.

I have a spare one of these frames, by the way, if anyone would like one

ah

i think this is what "they" call the "flap latch housing".

> [...] and surround screws to the frame,

ok, so i took these things apart more to see whats going on - on the
right side, a rather smart P.O. put garbage bag over the frame and
screwed the other stuff into it through the bag, apparently to avoid
corrosion, and it worked well. i took the pin and two triple square
fasteners out, and what comes off is the rubber wing - and here is
where i am confused : on the wing, the unthreaded triple square holes
are there alright, but in the center, where the pin goes, are
_threads_, as if a part is built onto the wing. a brand-new wing from
pelican (OEM-94451203301) has no threads whatsoever.

the car is old (1987), so i am wondering if this threaded component -
which seems rather fixed to the wing - is part of the frame that broke
_from_the_frame_ as i took the wing off? on the "worse" side of the
hatch, this apparent threaded part certainly breaks free from the wing
with gentle wedging with a flathead screwdriver... i am writing too
much now.... so that part broken off of the frame - right?

brian - I have no idea at this point what you are talking about - take 3 or
four pictures and email them to me (do not post to the group, or reply to
this note) - find my email address from my web page, www.wbnoble.com and
I'll see if I can help take enough photos that what you are asking about is
clearly visible.

That's correct. A Cheese head bolt is any bolt that has a head that is a
"Disc with cylindrical outer edge, height approximately half the head
diameter". A socket head bolt is like a cheese head except the head is
taller. I think that bolts with XZN socket heads should more correctly be
called Socket head instead of Cheese head, but what do I know? :0)

... finally getting around to post something of a conclusion to this.

the key to my trouble was knowing that part 477-827-035-OEM "rubber
mounting" exists. i am not certain of the section number, but if you
get a catalog, look for "Rear Lid, With Rear Window", it is part
number 11, and is not easy to see in the drawing. as of January, 2009
it costs less than 20 dollars.

after that, everything makes sense. the "part" i am describing (vide
supra) is in fact _two_ parts, one of which is the "flap latch
housing", the other a "rubber mounting" that were quite stuck together
and needed to be separated with force.

was a fun thread though, i learned a few things, and my hatch is
working fine - thanks folks!
