When removing the rocker panels do you typically or have to extract the rivets in the threshold?

Posted by: Porsche930dude Dec 21 2013, 03:31 PM

yes

Depending upon what you are doing, you can remove the bottom fasteners and pull it out without touching the top.
You can use air or water at that point to get all the stuff out.

Again, if you buy 1/2 inch thick rubber spacers from the plumbing section of the hardware store, and longer stainless screws, you can space out the bottom and you won't see it, but all the crud can now fall out, all the time.....and never build up.

Anybody got a pic of that? I am looking to take my rockers off soon for the first time. Wish me luck!!

The good news is they have been off before since the alum. rivits in there arent stock.
The bad news is ...who knows what youll find lurking beneath.

better to drill out and replace the rivets rather than have the fasteners on the bottom of the rockers snap off in the pan.

Hi Ray, be careful to remove just the head of the rivet.
Don't enlarge the holes.
The three machine screws below can be a much greater challenge.
If they are stubborn soak em' with your favorite juice..... for a few days.

Ray, there's also one each at the front and rear upper corners, but they remove pretty easily.

It's like a box of chocolates, you never know what your gonna get

And as much fun as opening your wife's Christmas gift....maybe..

try your fav hardware store for small stainless screws to replace the rivets.

I was lucky enough to get a bag of Tod's replacement plastic rivets before they went NLA.....
....the previous owner showed me a pic of the jacking point pod that had some rust and needed some attention. I figured since we're in Winter mode, I'd take them off and do some POR15 or just clean them up; then maybe do the Towle spacer suggestion to keep them clean in the future.

Plus the screws allow easy access to the longs for cleanouts, inspection, etc.

Posted by: brant Dec 22 2013, 09:13 AM

best to take these off annually or bi-annually
it can be scary under there
hoping for the best!

why the por-15? mar-hyde or ospho, prime and paint to match. with a color code your local auto body supply would be able to load some paint in cans. bomb it and be done with it.

Rivets are great, quick and easily drilled out. That being said; use only "blind" rivets. They will not allow water to pass thru the head as a std pull rivet will. Available at Aircraft Spruce.

Well if you are going all the way in, yes, you need to remove those threshold plates, or at least the outer fastener.
The rocker cover has a lip.

Posted by: rhodyguy Dec 22 2013, 04:47 PM

the threshold doesn't need to be removed to pull the rockers. at least on my car. plastic rivets have never been replaced while i've owned the car and the rockers have been taken off and on. a few times.

Giddyup Ray, time for some pics.

Posted by: rmital Dec 22 2013, 09:00 PM

A little worse than I thought it would be considering there's no other cancer on the car. I don't use the jacking point so just gong to clean it up, POR15 it, put the panels back on and drive.
The pod is shot, the longitudinal is solid.

I was surprised to see there was already some work done; sine the long is painted black

Posted by: tod914 Dec 24 2013, 01:23 AM

Ray, that's on your silver car? Wow I'm surprised. That car is super nice, including all the usual suspect areas! Trick to the plastic rivets on the door sill plates, so you can do your "seasonal maintenance", is to clip them so they they do not go into body. My original link showed how you can do that. It's buried some where in Andy's archives. Give me a shout if you need clarification on that.

Posted by: rmital Dec 24 2013, 06:10 AM

yes, good reason for seasonal maintenance. The car got around, starting it's life in Connecticut, then to Houston and ending with Glenn in California.
It must of had a nice bunch of crap packed around the pod, holding moisture.
Maybe down the line I'll replace the pod, no reason at this point.

When you feel like laying on your back, look at how the rocker cover fits to the bottom of the long.....it's tight to the bottom, but that makes it tight to the bottom outside edge of the long.....so nothing can escape.

Then look at how the tire flings direst and sand in there.....with the vibration, it magically gets in front of the jack point (see the stain)....

Now just hang the rocker cover on there , put a screw or two in the top to hold it.
Pull the bottom out, as if you have about a 1/2 inch spacer under the bottom of the rocker.....

When you creat about a 1/4 inch space between the rocker cover and the outer long at the bottom outer edge, then the sand and salt have a way to escape.

When you stand up, if done right, you cannot tell there is a spacer.
Too much and you can tell, but all you need is a place for the sand to vibrate out of there.

The nice part is after that, you can stick a pressure washer in from in front of the rear wheel and let it rip.....after some time all the water comes out clean....

...any chance you know the specific size screw; to avoid picking up an assortment to narrow down the size.

Posted by: r_towle Feb 5 2014, 05:34 PM

Nope, but the rivet is 1/8 inch , so go to a decent hardware store and tell them that...

Or bring along some calipers to measure the inner shank of a sheet metal screw...should be less than 1/8 th by a bit....
