Specification for spindle diameter?

Post by frank_w » Wed Jul 02, 2025 1:42 pm

More precisely, the diameter of the machined surface where the inner wheel bearing sits. I bought two used spindles from one of the suppliers, since mine were abused (strawberried) with a center punch. The left one measures 1.190" which as far as I know is how it should be. The right one measures 1.188". Is it still good to go? Should I look for a better one?

These are the values I came up with when I looked into it a few years back. I don't know if these match the factory print.

In hindsight it would have been easier to contact the Benson Research Centre and asked for the drawing.

Drawing (can't see much) of 1 piece spindle. Discussion indicates 1906-1927 same diameter but a bit longer surface for roller bearings

Ok, so the drawing says 1.189 - 1.190 which would also conform to the 30.210 - 30.226mm measurements. I'll see if I can find someone to build up some material on the spindle and machine it back to spec. Thanks a lot for your help!

That’s what I ended up doing. I had mine metal sprayed and then ground to size.
