New Items for Weber DGV DGAV Series

[bigjim5551212]

Our company has come up with 2 innovative items for the Weber DGV and DGAV carbs.
1) Throttle Shaft Repair Kit. This is a bearing kit that fits onto the throttle shaft without any machine work. This gets rid of all the slop and makes tuning a breeze. Price is $20 per kit

2) Proper Original Style Top Cover Gasket. Weber has been supplying the incorrect gasket in the carburetors and their repair kits for sometime now. We have the proper ones. Price is $5 each

Proper Gasket

Improper Gasket

Both these items are available by calling Overseas Distributing in Vancouver 1-800-665-5031

How about a detailed explanation on what these two enhancements can do for the 32/36 carb.

The throttle shaft bearing kit stops all excessive movement in the throttle shaft in the body of the carburetor.

As it is that the carburetor body generally wears and not the shaft itself. If you have any movement in the shaft you are getting unregulated air into the carburetor. This kit requires no machine work as there is a gap in the body of the carburetor for where the bearing slides into. The kit comes with instructions and the only real work is to take out the throttle plate and to clean everything up and reassemble.

Here is the bearing installed. However the bearing does slide further into the carburetor.



For the Top Cover gasket, Weber and repair kit manufacturers have been putting the wrong top gasket in the carbs and the kits. This doesn't always create a problem, but on high G situations and high angle situations, fuel can flow from the float bowl to the air corrector jets. Our gasket is the proper one for the DGV series. The other style that is being installed in fact is a 38 DGAS top cover gasket.

I get it. Man, could I have used something like that for Mazda B2000/2200 carbs. They all ended up leaking really badly at the throttle shaft. I would imagine the Weber shaft will eventually do the same to the bore of the carb housing and cause leaking. You can check your carb by spraying a little carb cleaner in the area to test your carb for leaking. Sounds really like a really good product to me.

Are you setup to purchase on-line? What payment types and in what currencies do you accept? PayPal, CC, . . . ?

[booeman]

do you offer new butterfly to shaft screws? it seems they tend to strip easily.

Probably because they're "staked", but you can get them here . . .

The 1975 Opel fuel injection throttle body has a similar problem with bushing wear at the throttle shaft causing vacuum leaks. It would be great if a similar "Kit" was available for it.

[bigjim5551212]

the kit does come with new screws. I would suggest that you run a chaser tap through the throttle shaft to clean up the threads. You can stake them yourself or use Loctite.

We take Paypal ( oasales@dowco.com ) you can phone and order them and we take credit cards over the phone. Our new website, www.weberjets.com - Coming Soon, is nearly ready and there will be online purchase there as well. You can call 1-800-665-5031 M-f 9-5 pacific

BigJim are these needle bearings or is there some sort of polymer between the races? I am glad to see this product come out as I have two webers that need it.

[bigjim5551212]

these are roller bearings. Actually we have a new bearing that is slighly different in the look, it has a metal seal.

[Cruz]

I assume that this will seal the shaft as opposed to having new bushings installed,
And what is the cost of the bowl gasket?

[bigjim5551212]

The Top Cover gasket is $5. If you are going to do the top cover gasket, you might as well do the bearing kit as well. $20 for the bearing kit, $5 for the gasket, and $9 for shipping. We ship in a padded envelope and the gasket is in a sealed plastic bag.

[bigjim5551212]

BTW the factory "seal" does squat in my humble opinion. It may have stopped some vacuum leaks, but it does not support anything.

I have a theory.

When Ford asked Weber to design a carburetor for the 1969 Ford Capri, they submitted a design to Ford. Ford said make it cheaper. Weber did, they took out the throttle shaft bearings and put in a cheap bushing. Why would Weber have a hole in the carburetor with a seal that did not go to the outside of the housing? They originally wanted to have a superior carburetor like the DCOE series that had bearings, but someone decided to cheap out.

[Paul]

FYI on bearings the meal is a shield. The rubber is a seal. If you are tryig to reduce vacuum leaks, go with a seal not a shield. Better yet go with a bronze bushing and ream to size.........

[bigjim5551212]

The roller bearing is a direct fit. It works better overall, The bearing we use has a rubber seal with a metal shield. With our kit, its plug and play. no machine work, no reaming, no fuss, no muss.

For your friends with Formula Ford Race cars, this kit is approved by the SCCA

[bigjim5551212]

BTW the bearing kits fit the 38 DGAS and the 32 DGV.

No reason it shouldn't fit the "DF" series carbs too then, right?

The only real difference between the DGxV and DFxV carbs are the primary/secondary orientations - DG - left side primary (looked at from front), DF - right side primary - where the "DF" series are generally considered the "Ford" carbs.

So, 32/36 DGxV and DFxV, 38 DGAS, 40 DFxV and DFI/DFO (sprint)?

[bigjim5551212]

No, the DFAV is a similar carb, but not the same design. The DFAV has no space for a bearing and the shaft runs in the carb body right to the outside. I have looked at that carb, and there is no room for machining. This is a carb that you might be able to make a bushing, but you have to set up a jig

40 DFAV uses a seal, but there is no room for the bearing kit,

40 DFI, I have not seen any lately to remember. 40 DFO, they are so rare, I have not seen any.

IMO the 40 DFI is not a great choice. Why? Because it has no power valve and you have to use gigantic jets. However its advantage is large venturies

[bigjim5551212]

The truth be known, alll these common carburetors are Ford Carburetors.

I don't think anyone here is using them as a direct replacement on a plenum-style intake. A few of us have the Rekord 'Sprint' intake manifold, which utilizes twin 40 DFO Webers. So they are an individual runner application, power valve not needed!

I managed to score a bunch of NOS Ferrari 40 DFI's from Impact Parts many years ago, and used them in place of the DFO's. Same design carburetor with interchangeable bits, just a different top hat which makes air filters a bit easier to fit.

The Japanese never figured out how to make their own carburetor. they copied everything, including the bad designs. We supply adapters for every kind of Japanese car with a carburetor nearly to put a Weber on.

[ungermm]

I've known of leaky throttle shafts ever since I got into playing with carburetors.
My experience has been that a vehicle with this problem will have a hard time at the lower RPM's to run smooth and may even stall. However, I wonder why a little leak could cause so much problems when the carburetor itself sucks so much air. Is it the location of the leak?
Jerry

[bigjim5551212]

The issue is that you can not control the air flow if it is NOT all going throught the venturi of the carburetor. Leaking air can cause a lot higher RPM at an idle. Sometimes there are other areas of air leakage, namely the all the gaskets, and the vacuum hoses, besides a worn carb body. Sometimes you have to look at the brake master cylinder as well, if it has vacuum brakes. There can be leaks there and they go right to the intake.
