Title: Missing air box piece; where to get it
Post by: jfrabat on August 08, 2015, 02:57:20 PM
Afer wheeling, I took the Jeep to get it cleaned.  Had them clean the undercarriage and motor.  Friday, I was taking a peek under the hood, and noticed this peace is missing.  Anyone know what's it called and where I can get it?

I don't think it has a name and you can't get it without getting a new airbox.  It's basically a cover panel, IIRC.  I'm not sure why it's there though.  May have been used as a duct for early XJ?  I thought the panel was plastic riveted on though.

I had never seen it before, but now it surely is missing...  May have to get a new airbox to get it out of, as otherwise the snorkel is kind of moot....

Its just a flat piece of plastic I would just make one and use screws to hold it in place.  Using some type of sealant so water does not get in.

Do you have a store specializing in plastic?  Otherwise, cut some metal and RTV it to the box.  Don't even mess around with trying to screw it into place.

It looks a hot air intake option.  :wall:

Sealing with RTV seems to be the best way to fix it because even the factory cover might leak.

Since I had my Jeep disassembled I took some pics.

I still have to do that...  And I have the clubs anniversary this weekend, so some wheeling is likely to happen!  But the brakes are still at the top of the list...  Have not fixed those yet either!

I played around with the airbox while I had it out.  So I popped the panel out.  It's helded in by those 4 pop-rivets.  That's it.  I took a screw driver and popped them out but saved them.  Looks like all you need to do is trace the opening, drill 4 holes that correspond to the holes already in the air box and either use screws or pop-rivets.

Thanks Jeffy!  While you have it out, can you measure the thickness?  I wanna try to get something close to stock...
Title: Re: Missing air box piece; where to get it
Post by: Jeffy on September 25, 2015, 10:47:28 PM
I can measure it tomorrow but I'd say you can measure it from the lip left on the airbox.  Thickness doesn't really matter though as long as it seals.  For you, you need it to seal since it will bypass your snorkel.

just use 2mm aluminum, can be thicker (you want it thick enough so it won't warp so the thicker the better)
Title: Re: Missing air box piece; where to get it

Whoops, it's 3mm...

good time to put some silly-cone under it  :smokes:

OK, I have been having a hard time locating a piece of aluminum or plastic (ABS or policarbonate) to put there that will not cost me an arm and a leg.  SO far, every place here (local purchase) wants to sell me a 8' X 4' sheet.  I just need a couple of inches worth, so that's not in the cards.  Looking around the house to see what I have available, I came across a Rubbermaid case that I can cut up.  Do you think this will be strong enough and will withstand the heat?

I wouldn't use clear plastic.  It's usually the weakest.

I think it would work well.

It's not CLEAR CLEAR...  It's kind of frosted...
Title: Re: Missing air box piece; where to get it
Post by: Jeffy on November 23, 2015, 04:51:44 PM
Clear/frosted aren't that great when it comes to heat cycles.  They tend to harden and dry out faster then other colors so you might want to check it every year.  You can use anything though.    It doesn't have to be plastic.  Sheet metal, tupperware top, etc...

if you have a raw pcb board that would work (with no holes of course), you can cut it by scoring it with a knife and it's tough as hell, 1.2mm, 1.6mm, etc - would work.

if not just find an old metal box from something and cut the piece with an angle grinder.

Home depot and lowes and Ace Hardware all sell AL sheets in smaller sizes.

Kinda hard to do when you're in Central America though.

Yup.  No lowes or HD here.  And hardware stores are targeting DIYers, so not as.manybraw materials.  I am trying to get AL, but if I cant, I have some carbon fiber sheets laying around...

During my Xmas break, I went to Panama to see the family, and strolling through the hardware store, I noticed they had small aluminum sheets.  I got a piece of stock .064 X 4 X 10 inch and made the missing piece (I was THIS far from taking some of the carbon fiber I had laying around for the multirotors, but this saved me from having to do that!).

Here's the piece already made.  Notice I srubbed the borders, so that the silicone will have a better surface to adhere to.

Here's the airbox all cleaned up (it was not really that dirty to begin with)

Now, I have some black LocTite brand silicone, but whatdo you guys think?  Just the silicone, or use rivets as well?  I only got regular rivets, so I am leaning more towards the silicone alone...  But I guess if its not going to be enough, better to do it right, as I don't have any more aluminum to make another one!

It doesn't matter as long as it stays on there.  It doesn't have to deal with pressure.  If anything it would be a slight vacuum.

Soooo...  rivets (regular)?  Or just black silicone?
Title: Re: Missing air box piece; where to get it
Post by: jfrabat on January 02, 2016, 05:58:17 PM
Well, I went with the rivets.  6 of them, in fact (figured if the old 4 got ripped off somehow, better make it a bit stronger, so between the silicone and the 6 rivets, it should hold!).

Here's how it looked mounted on:

(http://i46.photobucket.com/albums/f138/jfrabat/DSC_0106.jpg) (http://s46.photobucket.com/user/jfrabat/media/DSC_0106.jpg.html)

And after a quick dose of spray paint, it blended right in (ot looks white because of the flash, but it is mate black)!

My drill press is basically shot, as the head is dancing all over the place, so some holes are not perfect, but I think it will work just fine.  I filled in all holes with the black silicone and also put silicone on the inner and outer lip.  Tomorrow I'll dunk the whole thing in water and see if its water tight or not.
