RE: ZF parts

The balls are standard 1/4" ……… the race is unique ……… have not heard of any source.

Still waiting for somebody to try the "Tim Ken" bearing (#29 in drawing) that the 356 people have reproduced is the same as the 750 piece.

Mine are a (2) race with caged balls, one on top, one on the bottom of the screw part
of the steering. Will take photos.

This is on a '62 Giulia Spider.

Hi Alberto,

I looked hard to find these parts, without succes.

I replace the old parts in the steering box.

The bearing is similar to the one in VW beetle classic steering box, but unfortunately not the same size.

Chris, in love with Alfa from...'68, but it wasn't always reciprocal !

Those are completely different from my earlier "kidney shaped" units. Maybe they are available. Have you tried taking them to a bearing supplier like Motion Industries?

As I live overseas, It is rather difficult to send to the USA.

Is it only my steering box that requires help?

Past Alfas...
59 102 Touring (first Alfa $500 running)
65 Sprint GT (2nd Alfa, $500 daily driver)
102 Sprint (never did anything with it, but wish I had)
74 Berlina (first new car - now certainly rusted into oblivion)
61 Giulietta Spider G-Prod Race Car (where is it now?)
84 Spider Veloce (rarely drove it, so sold it)
86 Quadrifoglio (Dull car - no more 115s for me)
1971 Montreal "The Full Monty". Fair winds and following seas

Current Alfas
59 102 Touring Roadster - restoration complete, enough Alfa for any rational man. Or irrational, for that matter
Oops. Add to the "present" list, 10204 01488, 2000 Touring Roadster project

And past...
Two 1946 Stampe SV4C (c/n 294 "Rocinante" - wife's favorite airplane. RIP), and c/n 235 "La Bon Temps Femme" (gone to a new home, but never forgotten)
Zlin 50LA (+9 -6 gees, titanium spar, 1200 lbs, 260HP rumored to now be in Brazil)

Starduster Too (recently spotted at the Nevada City, CA airport - over 20 years and an entire continent separating it from our stewardship in Binghamton, NY)
1955 Cessna 170B (wife taught me to fly tailwheel in this)

And present...
64 Mooney M20E ("Rambo". My faithful steed for over 40 years) Over 55 years old, and just returned from a trip to Argentina in him
Newest in the fleet
1967 Piper Super Cub on Wipline amphibious floats (a true "all terrain vehicle")
2010 Triumph Thunderbird


You can snap roll an Alfa only one time...

No, unfortunately they have no marks whatsoever.

Did you take them to a business specializing in bearings ……… they will measure and see if they can make by type and measurement.

Yes, but where I live it is a different reality (Central America) and by the time you are through
scourging through 20 or so NOS parts places, you have spent too much time searching.

I need a surefire thing.
