Among the parts I received with my Coupelet were four sets of planetary gears for the transmission.
One set has rivets holding them together and the other three are one continuous assembly.
Can anyone shed light on the differences and years?
Thanks,
Philip
Phillip, the one piece gears are the later ones, but I cannot tell you when they were introduced. Because the gear teeth are narrower they wear much more than the rivetted gears. I much prefer to use the rivetted gears with the full width teeth, as these do not wear anywhere near as much as the one piece ones, but the rivets must be tight.
Often the only way to tell if they are is to push out the bush for re-bushing and then check them.
Hope this helps.

Rivet ones are the early, to about 1917
I'm sending a set of riveted ones to Dan McEachern for needle bearings next week.
Thanks for the info. Will use the riveted gears that I have. They appear to be new with some light surface rust. I'll think they will clean up just fine.
Needle bearings would be nice also, how much does he charge?

I set up a riveted triple gear in my lathe to bore a new bushing to size.
The gears didn't run true to each other.
Impossible to true it up to the gears.
It doesn't look like Dan gave me a special price, so I'll copy what he sent me:
--------
Hi Ralph- price is $225 installed in your gears- includes machine work, bearings and new pins. also includes balancing to equal weight.
Pins are stepped and have a 1/16" wide step at the flywheel end just like the original Ford pins. The press fit diameter on the pins is .782, but I can grind to another size to fit your flywheel. the press fit diameter has about a .0005" taper to help with installation.
Lead time is 1 week unless I get buried with work at the moment your parts show up.
Riveted gears are ok- harder to balance sometimes, but they seem to have been made from better material or a better heat treat, so the teeth tend to be in better shape. of course the rivets need to be tight.

There were real good testimonials about Dan's setup back in about 2005 forum.
I have a flywheel with new pins and bronze bushings ready to go, but Jersey George's research convinced me to go with Dan, who says he's had no failures in 100 engines.
NOTE: you have to push the pins out from the long end, as they are stepped, and will crack the flywheel if pushed out the wrong way.

I would be careful with the riveted gears. They may not wear but the rivets do come loose. I have opened up more than one transmission where the gears were so loose that you could see them shifting. That can't be good! There are plenty of good one piece gears out there and they will last a lot longer than we will.
