Big beef linkage

slalombuggy · Posted: Thu Oct 01, 2015 6:15 pm Post subject: Big beef linkage

Looking for a better linkage for my 51 EPCs. They sit on CB Bigbeef (TALL) manifolds and I run an alternator and CB breather box on the stand. I ungraded the rod ends but the cross bar sucks. Anyone run a center pull linkage with this combo?

BERG

It's worked for 30 years, 4 engines and 3 different carbs.

my std hexx empi cross bar works fine with my 44's & big beef's

I dont not like the HEX bar linkage either. I think it looks crap along with the berg and any other that obstructs the view of the fan shroud.
I have scat center pull with 44's on big beefs, not 51's though.
It took a few shims to get the right-side bar under the alternator, but it works fine.

Any one that thinks bolting the linkage to the fan shroud (sheet metal) is a good idea has drank way too much berg tea. How many coils have you seen break off the shroud? Now it is a good idea to bolt a piece of angle iron from some rednecks garage to the shroud? Rolling Eyes

I bought the Gene Berg Fanshroud mount linkage :http://www.geneberg.com/product_info.php?cPath=8_230_2837&products_id=825,

And the CB PErformance Hexbar linkage:
http://www.cbperformance.com/ProductDetails.asp?ProductCode=6480

And the CSP Bellcrank linkage:
http://www2.cip1.com/ProductDetails.asp?ProductCode=C31%2D129%2D941%2D110

I didn't like the Hexbar system at all. Seemed like a sloppy bearing system for the arm. Also the CB Performance air cleaners will NOT accept a genuine K&N air filter.

I wasn't that impressed with the Berg geometry either. Any vibration of the fan housing is going to vibrate the linkage rods.

The CSP bellcrank linkage seemed to be the lesser of the evils, so that's the one I used. It's main flaw is that the carbs may not be synced well when the engine is cold.

However, I did have quality issues as the ball ends were NOT properly staked onto the carb linkage arms. I returned them a couple of times before I finally had them ship me a pair of threaded ball ends that I bolted to the carb arms and clearanced the threaded ends that extended beyond the nuts.

I also needed to install the CB Performance "Weblink Conversion Kit": http://www.cbperformance.com/ProductDetails.asp?ProductCode=6455

That had to be modified to fit. Here are the modification that I made:
http://www.thesamba.com/vw/forum/viewtopic.php?t=295815&highlight=weblink

I do need to add one more photo showing some additional clearancing that I needed to make to the Weblink arm.

So far it seems to be performing well.

However, I'd really like to see someone with 3-D CAD software do an analysis to see how well the the carbs are synced throughout the range.

Ater installing the CSP bellcrank linkage on an engine with IDF's and an engine with IDA's I will never use any of that hex bar crap again. The 2276 in my Ghia has the CSP linkage with IDA's on Bugpack manifolds without any clearance issues.

Did you have aluminum crossbar? Mine came with steel crossbar and ordered for big beef manifolds. That thing is really strong. I do remember the aluminum ones in the old kits through.
