Hub Production History

[pjdeb]

Pulled the rear wheel hubs today. Found that the are different. Someone must have replaced on somewhere along the line.

One side has 1/2" groove. Perfect for the red flanges on a Mitchell puller.

The other has a groove slightly smaller that 3/8." I had to grind the faces of the smaller black flanges. Highly recommend the Mitchell puller.....two sets of flanges, solid construction, large hammer/bump spot.

Anyone know the history of the hubs used? Changes from 28 thru 31?
