84 Caterham 7 rear wing fix

[DB6]

Can anyone tell me or (take a peek at their car) and tell me what the fastener is for the top inner mounting hole on both sides.

I see regular bolts (about a 1/4 to 5/16 or so) , washers and nylock nuts on the inside for every hole but the top one which seems not to have clearance emough due to the sping coils to get a nut and washer on;

were these self tapper screws without nuts on the back originally?

The reason I ask is that I just have empty holes on both sides and notice a bit of creak and movement between wing and body due to no fasteners whatsover.

 

Thank you

On my 2000 Caterham, the rear wing fasteners are all the same all the way around the wing. They go into rivenuts in the side skin. Except for 3 that go into the boot and those have washers on both sides with nylocs.

 

If I remember correctly they were M5x20 bolts. I've replaced my steel ones with nylon ones.

 

I only use 3 or 4 bolts to hold on the wings I use for autoxing. If they are tighened, they hold the wing on very securely, and if I hit a cone, they nylon bolts break off and do not damage the rivenuts or sideskin.

 

If you're only missing a couple of bolts, check that the others are snugged up. Tom

Thanks Tom,

 

I do not see on my car how there is room for any kind of back nut on the uppermost hole due to lack of clrearane with the spring .

David, the rivenuts are in the sideskin and the bolts screw into them. (however, could they could have been ripped out by the previous owner and never replaced???)

[DB6]

Possibly, however, there is hardly any room at all due to the spring coil, I am guessing that the coils clipped the nuts and popped them.If you put your fingers back there it is VERY close.

Here's a pic from my build. If you look real closely, you can see the small silver colored rivenuts in the skin where the wing attaches. Tomhttp://usa7s.com/aspnetforum/upload/1231750467_diff install.jpg

we have dif hole patterns, mine is 84 live axle, you do not have the top holes I have the prob with.

Thanks

Ok, no problem. but like I said, snug the others up tight and that might work. bTW, are you using the black welting between the wing and the body? That should fill any gaps and stop the squeaking. Tom

Yeah welts are good, it looks like I may have to tap a thread in it and use a short bolt, it must be a common problem I imagine.

 

Here is a pic I just took.

Again,if that's the only bolt you are missing, seriously, don't sweat it. Trust me, The wing won't fall off. Tom

Tom,

I know that;)

however it has the same whine and pitch that my ex used with me when I was in trouble.(it's like she is sitting on my shoulder when I get in the car.

Gives me the shivers:cry:

 

I guess I will just have to drive faster.

Hi DB6,

 

Looks like you might be hearing your shock spring rubbing on your frame from the looks of the photo you posted.

The other option you have is to move the bolt hole over about a half inch.

Just an observation.

Is there enough clearance if you reverse the direction the bolt is fitted and have the head on the inside?

Thanks for the input guys,

There is really no room for any nut or bolt head that I can feel back there, it is that tight.

The sqweaks come from the wing/ welt /body not the coil, that does clear the body.
