Going to look at a rolling (supposedly 1933) Chevy sedan chassis, how can I visually see the difference between standard and light duty spindles? Thanks
From the research I have done seeing if disk brake swaps are available anyone offering a kit says they fit standard duty spindles and not light duty. If they are light duty they will won't fit my needs.
As I recall, the Chevrolet parts catalog listed one part number for cars with straight axles from 1928-40.
They offered the standard duty for all those years, they only offered the light duty from 33-36, but both was available from what I understand. I'm definitely not well educated on Chevy stuff though, just going off info I read online.
What I am finding is inner wheel bearing ID. There is one inner wheel bearing that fits most 29/40 front spindles. The inner bearing is larger ID from 41 to 57. For years I thought 48 had a smaller inner wheel bearing ID until I figured out years later that I had a 40 or earler axle under the front of my 48 when I bought it. The outer race is the same and the bearing is the same but the inner race has a smaller ID for 40 and earlier. The bore for the inner race should be 1.190 Thats on a National B02 set. The 33/36 standard is by it's self. The Filling station didn't give bearing sizes nor did Chevs of the 40's for the others I was double checking the year to year differences there.
It looks like you have plenty of information now to figure out what you have. The late Pat Ganahl was very knowledgeable about early Chevrolet stuff. Read his article for good info.
I ran into this when putting disks on the front of my '37 truck. I ordered a kit for a '37, the bearings wouldn't fit what I had, turned out to be a newer Chevy axle someone installed back in the '50s or '60s, it sat in a fence row for 40 years before I purchased it. The newer axle uses spindles with a bigger inner bearing and king pin diameters.
