Bell crank linkage

[Joel Mohr]

I've been developing a cable system myself.....I should have it on the market after the first of the year...the only drawback is not have something to rev the motor from the engine bay.....mine mounts on the firewall side of the carbs....For IDF and Dellorto right now.

The Scat linkage doesn't use bearings. I used a couple bronze washers to act as bearings. I'm not a fan of the Scat linkage. The website description is vague and so are the installation instructions.[/quote]

Well there you go. Just proves that you get what you pay for.
I want one of those cable pulley setups with a center pull rig that slowtwitch (LinkSync) is making. I just PM'ed him on STF. I would like to get one.

Joel, make it for the rear so you CAN rev it. You know, in your face is better than out of place.

I would use one of these. I drove the JKM linkage in my bug, I love it

It's the same design, at almost twice the price as the CSP linkage. What about it is better?

My 2cents-I've used the cb hex bar for 1600miles now.( I do know how to adjust it)- and from the beginng when the motor would warm up, the linkage would stick and not return to an idle. (about 2000rpm) I installed a spring on each air cleaner to the throttle arms, which worked but makes for alittle stiff throttle. Made the springs as soft as a pull as I could and still is alittle harder of a throttle than I'd like. This weekend I installed a CSP linkage. Installed a lite spring as mharney does from the alt to the center pull. The throttle pull seems almost like a stock unit now-What a difference. I openned the hood to check the linkage after the maiden trip and found my spring had fallen off of the center pull side, I drilled a small hole in the alt but slipped the spring around the cable barrel bolt I'll drill a small hole in the center stand, but even with the spring it's night and day. Might not even need the spring but since it doesn't feel any difference, it's my piece of mind.

Oldbugr, I had the same issue with the CB hex bar. I read all the reviews I could and decided that CB made the "best" ICT kit, so I went for it.

However, ever since I installed it, I've had issues with whole linkage binding up and the throttle plates never quite closing to the idle stop. I pulled apart the whole pedal cluster and rebuilt it again, checked and relubed the cable tube, and lubed every heim joint and pivot, but the damn thing would hang up every time i drove it. I'd have to blip the throttle at every stoplight to get her to idle down.

I tried different linkage geometry, heavier carb springs, TWO springs (on the alternator and FPR.) Still binded up. Now, I noticed that the extension tube from the lower heim joint to the carb throttle arm is torquing the plates out of shape. It's a lovely-looking design, but sheesh, what a destructive pain in the arse.

I just ordered the Scat linkage, so we'll see. It's just money, right?

Oh, btw, I see that some of you have added bronze bushings to the Scat linkage. Do you think that's the best upgrade for the setup, or has anyone tried teflon washers? Do you use grease, too? I'd love it to be like the CSP with bearings, but I know what i paid for, lol.

Cheers,
J.

I drove the scat linkage on my car for the last four years and it has worked just fine for me.

As for the washers I used some nylon washers on the pivot along with some grease and it performs like a champ.

I will also be using it on my new engine as well.

I use slightly modified CSP bellcrank and it works like a charm!

Well...I installed my new Scat linkage and WOW...silky smooth, light pedal. It's like a new car! I can actually feather the throttle and I don't have to stomp the pedal at every stop sign to get her to idle down!

The pressure required to close the throttle returns is so light that it will fully close both arms with just ONE throttle spring attached. Of course, I still used two, but the additional return spring they supplied with the kit was definitely not needed.

If you don't mind the head-scratching involved to make things perfect (and can forgive the complete rubbish Scat instructions that are missing images and appear to have been copied on an old mimeograph) I highly recommend their linkage.

Sorry, CB. I like your products in general, but in my situation, the cheap Scat bellcrank simply blows your hex bar linkage away. Best $70 i've spent.

Being that there is so many linkage experts here I was hoping that somebody could ID this set up. I have searched and searched but cannot find any pictures that have been the same. Notice the linkage bars are bent at the ends, I assume to clear the heat ports on the shroud.

I am have not figured out correct location to mount this yet, it seems to need modifcations to get centered on the case.

Bet you CBs gonna step their game up soon and come out with a new linkage.

Has anyone seen JayCee's new bell crank for the T3?

Looks like a home brewed set. But it could work just as well as the next in line.

My view at this subject:

Yes the CB hex bar has the wear issue that is referred to earlier in this thread. I use to modify the hex bar almost exactly like also menthioned earlier, with a bushing and machining the pivot balls flat on a 2,5 mm area. Once that is done it is the best lower priced system on the market.
Dave, if you think the hex bar system is bad wrt similar throttle position, you should take a second look down the carb throats with the push pull systems.
Push pull systems cannot stay in sync cold and warm. Its a practical impossibillity. When the linkage wear a bit you dont hear it as much because of some "built in" slack then.
The Sync link is supposed to be "adjust and forget" - Yeah right. But that system actually solved the throttle position issue more or less to the "T"
CSP has also a hex bar system that has dealt with the wear issue that the CB has by having the hex bar hung up in bearing instead, which give a nice and smoth linkage. I do wish they had used better joints instead of the stainless "click on click off" joints that are also used on the push pull version.

The CSP crossbar pivots on big heims, not really a bearing. I think there will be some actual ball bearing adapters for the CB crossbar linkage in the classifieds maybe next week.... or so I heard.
