Machine work on SU for roller bearings

Featured Replies

I thought you guys would to see what my friend is doing to put bearings in the su bodies for the throttle shafts.First he made a fixture to hold body in a machine block on a mill5338.jpg5337.jpg5337.jpg5365.jpeg5371.jpeg

Next he will get a blank drill rod to line up throttle shaft bore. If you like I will post more pictures on his progress

Cool, appreciate the pics, interesting project!  I always left this in Ztherapy's hands!

Agreed. Neat project.

Kinda confused what he was doing in the first pic with the aluminum rod turned in the lathe, but maybe it'll all make sense to me later. The way he's clamping the part in the mill vise, that lathe work seems unnecessary? Like I said, maybe it'll all make sense later.

So what bearings is us putting in?

Just a guess, but he probably turned the round stock to fit the carb bore, and then attached the round stock to the square block with a bolt.

As he explained to me this is to fit  bore of carb so when he works on throttle shafts they are square with the carb throat. Butterfly and shaft will work smooth. He was a fabricator for cart race cars. Worked for electromotive, Dan Gurney, A J foyt knows a little more than I do. Also using 10mm length roller bearings for added support of throttle shaft instead of ball bearings.

His been real busy. He teaches race car engineering and they have been building a Mazda miata and a formula ford for scca racing. The formula ford is their own design from the frame up. Soon as he does the shaft bores and install bearings I will post some pictures

If you can post some pics on his projects. For myself I would love to take a look.

Would love to see the Formula Ford!

The engine is a Honda Fit for the Formula Ford. They just finished building it ran it on the dyno. No pictures of the car. They are just starting on bending the tubes to build the

frame.
