Fitting a stock air cleaner on a Weber 32/36 - a few ?s

['76mintgrün'02]

I figured out why there is a difference in the way the air cleaner aligns with the mounting brackets, using the two different Stock Air Cleaner to Weber adapters.

 

You can see in this photo that the oval hole is not aligned the same way, with reference to the four mounting screws.  The one on the right has a Weber logo and the one on the left is unmarked.  I believe it is an early style JAM adapter. 

(EDIT: not a JAM adapter... not sure who made it).

JAM adapter (not)

The difference can also be seen here, when the single side is attached in the mount, the double is different than it was on the other adapter. 

This difference is actually being doubled though, because both brackets would be moved to accommodate the other adapter, splitting this difference.

 

I should also note that these brackets have been bent around to fit my (mystery) adapter.  I wish I had a stock set to test fit.

 

There is also a difference in adapter height.  (Weber on the right).

On the topic of painting them, I came up with a way to mask off inside from outside using some rigid cardboard.

 

This photo shows the inside already masked off with the disc I cut out above.  

I used the same tool to cut out another disc, that is the same size as the OD.  

The 'left over' piece fits over the housing, under the lip, on top of the clip mounting tabs.

I have not sprayed the inside of one yet, but I am one step closer to being ready.

What's with all those beautiful rings? Are you gearing up for a sale? Are those designed to hold the rubber seal press tight on the Weber adapter.  They sure look well made.

OMG, Tom!  2002 air filter housing as work of art...  ?

 

Best regards,

It does appear as though I have a few extras at the moment....

 

I had someone show me a photo of how they had trimmed the flange on the bottom of the air cleaner (nicely) and asked 'what next?'.  He is in need of a new rubber seal (still available) and one of these rings. 

 

The rings are a friction fit onto the existing (trimmed) flange and the seal gets trimmed shorter to work with the rings, or "feet"; but that is not hard to do.  Making these takes a little tooling up, however.  (photos above show a foot or two installed)

 

I decided to improve my tooling, by replacing the plywood form with an aluminum one and notched that hose clamp, to hold the band in place for tack welding.  I also made this little aluminum backer piece, to act as a heat sink for the projecting part of the band and just pop it out before bending it over the form.

Welding thin stainless is tough, because the back side gets ugly if the weld drops through, (without being shielded by Argon).  Getting good penetration is key, so that tends to happen.  Then there is the extra step of cleaning up the back side.  It doesn't take long, but each step adds time; which adds to the cost.

 

They are simple little things, but a bit of precision is required to get a consistent fit.  I skinnied up the aluminum form, took .020" off the band length and .025" off the band width and I think I am happy with the fit now.

 

This is sort of a fun photo, that shows a black lip that was trimmed off an air cleaner, with that other trimmed off lip, cut down to fit inside of it (as seen above/didn't work as I'd hoped/led to these rings).  Those are inside a stainless band, which is inside the stainless hose clamp.

It is too bad these are hidden from view once installed; but that doesn't mean they shouldn't be pretty, right?  It's all in the details... as they say.

 

Steve, I agree that these air cleaners are works of art.  The more I study them, the more appreciative I become.  The design is brilliant and beautiful to boot.

Gorgeous design from the TinkerMaster

 

Sign me up for one if you decide to sell in the near future. Heck, might even place one on my desk as a conversation piece and to look at. Gorgeous and functional.

Thank you : )

 

Since I do have a few extra rings and a couple people who want them, I was trying to figure out an easy way to ship them, and keep them from getting bent.

Pattern following router bits are empowering... so I indulged in making some discs to support the rings.

I used the welding fixture/bending form to make a pattern

 

Good use for some used T&G cedar.

and that pattern to make some inserts

 

I traced the oval onto this image from Roundel magazine, cut it out and put it on top of the wood.

I'll keep this one on my desk and hope someone asks about it.  (They'll be in for an earful though).

 

While at the Yank-A-Part, I picked up some e21 air box clips, which are too big for our air cleaner housings; but they do make a nice support for jplips' conversation piece.

 

Funny how one thing leads to another sometimes.

the off-cut became 9/16" tall gauge-block for shortening the st0ck rubber seal.

 

 

waste not want not, right?

 

(thank you again for the bag of tubes, Charlie!)

 

 

 

 

jplips, the larger piece of horse hair can be added to the lower part of your seat back, for added support.

I need a dust free 'booth' to spray in and am thinking of setting up a little visqueen tent in my shop.  The flat black paint job came out a little frosty around the rim and had more texture than I wanted to see, so I decided to sand it out and give it a coat of satin.  I took Paul Winterton's excellent advice, to preheat the lid (I used a heat gun, while spinning it on the lazy Susan and brought it up to about 100*F) and put the can of paint in a pan of warm water, which brought its temp up into the nineties.  Good call Paul!

 

I agree with Steve, that these air cleaners are works of art.  Painting is an art form too.  So is photography.  This is just a series of photos celebrating the beauty in the design of the 76 lid.  After having now spent six hours sanding between coats (6 coats... learning curve is a little steep) I have gotten quite familiar with the shape of these lids.

One more time... hopefully.

Tricky business, painting.

@BuzzBomb here is your write up.

There is an air cleaner for sale on eBay right now that has an interesting lid.  (NMNA)

 

Unfortunately, the outlet hole has been hacked already.

I have only seen one other example like this and it was in this photo of an early car with an engine swap.

It looks like the designers solved the problem of the logo being rubbed against the hood  (although, I suspect that is only an issue when retrofitting the assembly to a Weber).

 

Does anyone know what this originally came on?  Pretty sure it wasn't a 2002.

 

Here is a photo from another eBay listing, for an e12 air cleaner.  Interesting that it was made by Mann, not Purolator.

The way the clips appear to come from the bottom is interesting.

 

This e30 lid is quite similar... getting warmer, I think.  

 

The bolt coming up through the middle makes the dimple design seem logical, yet the first one in this post has not been drilled.  

 

The bases on these later models are quite different than the ones on our engines. 

 

I suspect the first one in this post has been mix-matched, using a later lid on a 2002 base.

That's hilarious, @'76mintgrün'02 ?

I'm resurrecting this thread to show off my new rubber bumper that goes between the fuel pump and the underside of the air cleaner.  The way the adapter fits the weber puts the air cleaner higher, so the original bumper no longer sits on top of the pump.  My original (to me) air cleaner came with a crack beside the breather vent tube and that crack grew (suddenly), so I replaced it with another one I had on hand.  Now that one has a crack in the same place.  I don't see why it they are cracking there, when that tube has a little bracket built into it, but am hoping that supporting it on the pump will lessen the chance of the crack spreading.  Here is that copied/pasted post--

 

I made a new rubber bumper yesterday.  Well, three of them, in an attempt to get it right.  It is a press fit over the original one. 

 

 

I am glad to have a stash of rubber bits to work with.  Here is part of my assortment.   

 

 

The rubber I used is nice and soft.  The first two attempts were too short. 

 

 

My air cleaner housing is well supported again.  I appreciate the nudge in that direction, John76.  I hope it slows the growth of that crack.  I don't feel like burning that pretty grey paint, or taking the time to weld it up just yet.

I could never get the Jam Engineering carb adapter to work with my stock air cleaner. Never quite lined up and was always too tall, and therefore did not sit properly on the mounting brackets or the rubber bumper for the fuel pump.

I took another approach. Used a round aluminum mounting flange and drilled, cut, and filed it to fit the bottom of the rectangular Redline air cleaner that came with the Weber carb kit. I adjusted the height of the aluminum flange to rest on the underside of the original air cleaner, while it was in the proper mounting position on the stock, unbent air cleaner support brackets. 

Once the height was established, the Redline base was J-B Welded into place.  I used HVAC foil tape on the underside and inside of the air cleaner before fastening it to the aluminum flange with stainless machine screws and fender washers. Doesn't look so good from the inside, but it is rock solid, no more cracks, and just as  easy to remove as the original Solex  design.
