Bernie Bergmann Carb Linkage upgrade- bearings

Bergmann stuff typically gets a bad rap on the forums, but some of his stuff is decent.

This is the linkage I run and haven't had any issues.  Works great, little to no resistance, no slop or slack.  The most important part is that my perfect sync and adjustment stays whether hot or cold, idle or WOT.  Make sure you get the down rods with heim joints too.

Trevor.. Which linkage do you run?  Your note did not say.  Is it the CSP, EMPI, CB, Vintage Speedsteed... 

Many thanks

Sorry bout that.  I use the Bergmann linkage.

Great, thank you..  The system looks prety ingenious, and simple to install.   Similar to some of the bearing  linkage mods I had read about in the forum... Most dated between 2009-2012.

Quote from Bergman's site:

Modifications not only for the High Flow Fan Kits, but also for linkages used with regular Dog House Shrouds, 36HP Shrouds and stock metal cooling fans

I see, in the photos, how it works with one of his copied 911 shrouds, but how does it fit on an engine with a regular doghouse cooler shroud?

Ron, I have a regular dog house shroud.  I'm told you use the stock EMPI/ CB carb plate... Remove the plastic bushing, and insert/hand press fit their custom bearing holder with the bearing installed in in its place.   

- Then, insert the stock EMPI/CB spring into the holder, and add some grease.

- then replace the ball nose with the one he provides. ( squared off nose. Screw on to stock hex bar.

- then re-install the stock hex bar into their custome bearing holder... You may have to be cut 1/2 inch on each end of the hex bar.... Depending on the length bar currently installed. ( as the bearing holder comes out 1/2 further than the plastic bushing used on stock EMPI/CB kits.

seems like simple modification if it really works...

if you are looking to redo your linkage - look at sync-link

I agree. SyncLink is pretty slick.

over the years I have used and installed several dual carb set ups.  the standard weber carb to carb linkage works ok, the berg worked fine once you get it setup right, the bell crank design works but there are several ones that are crap. The sync-link was challenging since my first two installs were a DTM and Porsche shroud but by far this is the best. reminds in of a multi carb motorcycle or snowmobile set up. It's worth the extra money. I just hope in the future he designs it so one can remove the motor or linkage without removing the main cable. I have done it but sometimes feeding the cable thru the ferrel is a challenge.

I agree, the Synclink is a great way to go.

This looks like a great upgrade for those that don't want to spend $300 on Synclink. I modified my CB Performance linkage with heim joints, springs, 5/16'" hardened rod and a couple washers. I think it cost me about $20 total, and an hour of time. I cut the ears off the air cleaner bases and bolted the heim joints in place, keeping the same pivot point. 

Back in 2006, when I had 3000 miles on the car, the hexbar was extremely worn on the inside from the original ball links. Sync was impossible to maintain.

I have since put 37,000 miles on my modified setup, with absolutely no wear, and no sync problems.
