Weber throttle shafts? Who fixes loose ones?

[jmz]

Bieker did some for me about 20 yrs ago...

Who's good at it these days?

Thanks in advance

There is only 1 guy that I know of; Paul at Performance Oriented. He is the best but you might need to get in line. You can read about him (1quicks) on most of the Weber carb threads on this forum. Again, he is the best.

Another very happy customer here, talk to Paul.

Matt at Eurometrix too but again--take a number and get in line

Where are they worn? There are plastic bushings behind the throttle arms on the rear of the carbs. Those are easy to replace. You don't even have to remove the carbs. I replaced mine with brass. Lasted for decades.

How much play do you have? How did you measure it? Is there play in the center bushings? How much?

Replacement of the plastic bushings (used on the triple throat Webers from early 1967 on through the end of production) has a couple of issues to be aware of:

• the plastic is easy to replace from the throttle lever end but the other end of the body requires removal of the short throttle shaft to access. Although this bushing is typically in better shape than the other end, I have seen these to be quite worn also.
• The replacement bushing will center the shaft well enough for awhile but a few thousand miles & you will be loose & leaking again.

Loose shafts due to worn plastic bushings allows the shaft to rub on the throttle body housing which creates a groove in the shaft & elongates the hole in the body itself. New plastic will center the shaft but plastic is a mighty poor bearing so it compresses during compression braking (throttle released) and soon the shaft is rubbing on the body again.

The picture shows where the bushing supports the shaft and the length of un-bushed shaft between the end of the bushing & the throttle valve. You can see the groove to which I refer.

Gordon is right in that you can make your own from sheet brass, I provided these once before for an Australian customer.
