VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1933-1936 Ring Gear Rivets

I have two different size ring gear rivets and need help identify them.

Overall length of the rivet is 1 5/8" and the other is 1 3/4"

I want them for the 34 Chevy Standard

Any information and help would be appreciated.
Thanks

if i were you i would bolt it in . it is really hard to expand the rivet so that it is tight . i have used heat a 50 ton press a air hammer a special jig . just put a drop of loctight the red stuff .hope this helps

I agree -- you'll never get the rivets tight enough to hold.
The gear is held by friction between the gear and the carrier (?), as it is not simply shear strength of the rivets that you have to be concerned with.
When I put new gears in my '35 Standard, my automotive engineer cousin convinced me to get the (1/4"?) holes in the gear bored out, and use larger bolts than would fit in the rivet holes.
A high-quality bit on a milling machine (with lots of cutting fluid!) got the job done on the gear, then I put in about 3/8" grade 8 bolts, tightened to just under the point of failure.
As I recall the mating holes in the carrier were already larger.
Hope this helps.

Thanks for the information about using bolts but I really want to know which size rivet was used back then. I have no intentions of changing my ring gear just want to know which one of the two sizes would have been used. Thanks
