Weber Universal Throttle Linkage

[andrewjoelpeters]

Hey all,
Made the weber swap, and things are looking good, except I can't figure out this universal linkage kit for the life of me (part no 99007.116). I'm embarrassed to admit it, but I'm just not seeing it! Has anyone else used this linkage? I didn't much luck with a search.




The linkage kit cam with a pin that fits through the throttle lever assembly, and can be held in place with a cotter pin. The pin is threaded on the other side, and seems sized right to to bolt on the aisan bell crank. This is the set-up I have in the photo above, and almost seems right, but I can't imagine the pin assembly will actually turn the throttle lever--I think it will just rotate in place.

I also haven't figured out how to use this piece, so maybe that's part of the trick:



Feel pretty silly for not being able to get this! A.J.

i'm not sure about the throttle linkage that comes with the weber. AFAIK, most folks here have modified the stock tercel bellcrank to work on the weber using splatterdog's technique. here's his post on it.

i made a post on the thread about securing the two pieces together using a small nut, bolt, and lock washer since i don't have a welder. i used that technique on a friend's terc a year or two ago and it worked well, in case you also do not have a welder.

My technique does not require welding: https://tercel4wd.com/forums/viewtopic.php? ... an+#p33319
The only part I used from your bottom pix was the spring.

Thanks for the replies! I think I'll probably go your route dlb, I don't have a welder and had gotten a little scared away from that technique. Tom, I meant to reply to you on the other thread--I realized that my kit came with the universal linkage, not the u-bracket, and just wanted to see if I could figure out a way to make it work.

I'll let you know how it goes.

Although, now that I think about it, it would be kind of nice to be able to undo whatever changes I'm making now. U-bracket, here I come!

A.J. -
As mentioned in that other link, my Weber kit came with the U-bracket. Did you ever call Redline on it - or the original vendor?
I don't think it would be too hard to just do some metal bending to make one, though.

OT, but - how is the clearance between the filter and the hood? I was able to get the short one on a swap with the vendor at N/C, but still wound up having to shorten the element by using a Dremel tool (after cutting out a portion of the hood's X-member).

I couldn't figure it out either, but I didn't try very hard as I found using the old bell crank easy to do and no welding required. Scroll down to my response.

Tom- No problems with the hood clearance! I saw the issues you ran into, and had my fingers crossed that I would be okay. I even kept the phenolic spacer too. Who knows why it worked for me but not for you. I do have a 1st gen, so maybe there was some difference in the hood design? I talked to Carbs Unlimited yesterday. Assuming this is the same u-bracket as yours (http://www.carburetion.com/Products/Pro ... =99007.170), they said it comes with the K746 kit, for the 20R and 22R.

Keith- Glad to here I'm not alone! That looks pretty darn easy. Have you had any problems with the side pull on the throttle lever? And what did you bend the bracket with? I had originally thought of doing something similar, but was afraid of putting too much strees on the intake manifold.

"D-Uh!" said Tom as he noticed your avatar and smacked his forehead... Gen I v. Gen II, obviously the hoods are different.

I still think you should buy/make* a U-bracket to interpose between the Weber and the OE bellcrank; it makes for a much straighter pull of the cable, easing sideways pull of the cable on the throttle shaft as well as less wear and smoother operation of the cable itself. While it was pretty straight on the 2008 installation, the 2014 mod was even better. While the 2008 install was a very minor misalignment of the spring (compared to Keith's spring), it contributed to wear on the plastic bushings of the Weber throttle shaft, causing a slight vacuum leak and subsequent stumble - which is why I installed the bearing kit https://tercel4wd.com/forums/viewtopic.php? ... it=bearing a couple of months ago.

While OT, while you have the cable loose, raise it and dribble a silicone lube down it until it drips inside the car (on a suitable rag); you will be surprised how much smoother the cable works.

* It would be easy to make - just go to a hardware store and pickup up a short piece of 3/32" or 1/8" steel strip and bend in a vise and drill.

I never had any trouble, but I only got about 30k on it before the car got totaled.

It's always the most obvious things! I think I will go the u-bracket route, seems to be the cleanest option. Thanks for the silicone lube advice too. I'll let you know how it works out.

I'm curious how it works out in the hot hot summer and our random cold winters...

[dlb]

i had carb icing issues with my weber but there is lots of moisture in the air here. a few peeps in cold drier climates said they have had no probs with icing.

[irowiki]

We're close to the mountains here so it is cold and wet here, even if we don't get much snow.

[dlb]

oh, crazy. well, if i could go back to when i had a weber, i would just start the car on cold mornings and let it run for a few mins while i was getting ready to leave, shut it off for 5 or 10 mins, and then start it back up when i was ready to go. a friend into motorcycles said that's what he used to do to prevent icing while his bike was warming up. i never got to try it but it seems like it should work since the heat created by the engine running for a few minutes would have time to warm the carb body past the icing point.
