Weber 40 DCOE Parts

[JLescenski]

Anyone have a good source for parts for the Weber carburetors? I am looking for parts that don’t usually come in the rebuild kits

Cold start screen - the little one everyone loses
Leather bearing seals - seems that the only way you can get them is with an entire new shaft and bearing assembly
Fiber washers for the cover bolts

Also, on a similar subject, is it worth going to sealed bearings on the butterfly shaft if the old bearings are still in good shape

Thanks for the input

I tend to use Piece Manifolds, they sell a seal separately but not sure it the correct one:

Personally I won't do the bearings if you can get a seal, unless you also wanted to replace the shaft too. This is due to risk of damaging the shaft when removing it.

You can cut your own leather seals - I'll have to go back and find my notes on thickness, but that is the simplest solution to getting the right fit. After cutting them, you just soak in mink oil overnight to add waterproofing.

EDIT: it was easier just to go grab the leather I had and measure it - thickness was just a bit under 1.5mm, about 3/64". Looking at it, I recall the process was to cut a piece big enough for the 4 seals I needed and to stick that in a cup of mink oil, where I left it for a few days. Fully saturated, I stretched it by hand as much as possible, then punched the inner diameter then cut the seals to slightly over the diameter of the bearing.

Not sure what the issue is, I've easily purchased new leather seals and bearings etc easily as individual parts, I'm in Australia and purchased form Weber specialist in Melbourne. In past I've bought similar parts from Pierce Manifolds in US and Webcon and others in UK.

I use 2 sellers on eBay that always seem to have small hard to find miscellaneous parts, Alfa1750 & carb.deals . They are both in Europe (Italy & Czech Republic respectively), so postage can be expensive, I try to group parts from the same vendor... If they don't have the part s that you are interested in ask, they usually have any & everything.

Cold start screen - the little one everyone loses

Part # 37000.016, available from Alfa1750 here - https://www.ebay.com/itm/WEBER-DCOE-IDF-CHOKE-COVER-FILTER-REPLACEMENT/262096808639?hash=item3d062feabf:g:jNAAAOSwT5tWINJg, Carb.Deals here https://www.ebay.com/itm/COLD-START-STRAINER-MESH-WEBER-38-40-42-45-48-DCOE-36-40-44-IDF-EMPI-HPMX/293829030591?hash=item44699332bf:g:u0gAAOSw-vdfrcpk & Europarts - https://www.carbparts.eu/?p=59X

Leather bearing seals - seems that the only way you can get them is with an entire new shaft and bearing assembly

Fiber washers for the cover bolts

Not sure what you mean here, what part # on https://www.carbparts.eu/exploded_view/WEBER_40_DCOE_early_type?

Also, on a similar subject, is it worth going to sealed bearings on the butterfly shaft if the old bearings are still in good shape

If your old bearings operate smoothly (no rust etc) you can reuse them.... otherwise this is an interesting discussion topic. The new "sealed"ish bearings will rely less on the leather seal to stop any air leaks. You can buy sealed bearings inexpensively (part #607-2RS) even on Amazon. Note you still need the leather seals, as SENC said, soak in Mink Oil before installing for 24 hours.

Be careful you have the right butterfly screw, sounds like you have an early carb, so the screws need to be of the countersunk variety.

Plus 1 for carbdeals. Have mostly had excellent service from them. The only problem I have had was a shipment around Christmas where the package disappeared. Daves at carbdeals tried to fine it, but wound up sending a second shipment to replace the original. He only asked that should the first shipment show up, would I please ship it back to them. The replacement arrived within a week, only to have the original shipment arrive several weeks later. I contacted Daves and told him to bill me for the second shipment, as I decided to keep the original as spares. Can't ask for better service than that. Used them before the deliver mixup and will continue to do so.

I got parts for my Webers from Eurocarb. I have no affiliation with them.

I replaced the seal washers and found I had to open the holes up a little because they were too tight on the spindles.

Thanks for all the input. I checked and the crab kit I bought includes the leather seals. Now I just need to find mink oil

I also bought some parts from our friends in the Chek Republic. Shipping is almost the price of some of the smaller parts so combining is definitely key

I thought Mink Oil was a wind up the first time someone mentionned it.

Here you go https://www.amazon.com/JobSite-Premium-Leather-Waterproof-Liquid/dp/B004X6SUZY/ref=sr_1_4?dchild=1&keywords=mink+oil&qid=1611495462&sr=8-4

Glad you managed to order everything from the Czech Republic, very good seller.

For leather I've always been fond of Nor-V-gen shoe oil. I'm sure any good shoe oil would do the job.
My bearings are rough from corrosion. I can't see that they would be a critical part and I'm sure that replacing them would likely do in the throttle shaft. Is it really necessary?

Kurt

[vstibbard]

They are easy to remove and as long as you are careful it will not damage the throttle shafts, make sure you keep all throttle plates and screw in order the were removed, when replacing the throttle shafts, fit screws but don't tighten them until the throttle plates are settle into the throat of the car again, then tighten. I replaced mine with modern sealed bearing and leather seals.

Agreed, the videos in this series give good instructions - https://www.youtube.com/watch?v=c-YJdzhgrkw

You will need new butterfly screws.

If the throttle shaft bearings are rusty the throttle shaft will not operate smoothly, so now is the beat time to replace the bearings with sealed ones.

[nomad]

Thanks. They will definitely need seals so I'll see what's involved when I get into them. I'm afraid that corrosion might not make it an easy job.

Kurt

[vstibbard]

the bearings maybe corroded internally but they still seem to come off the throttle shafts easily, Id use some penetrating oil or freeze spray if unsure.

well,I prefer to think twice before putting Weber carbs in an hydraulic press (esp. crooked) ...
