That's a very clear photo. You could find the ratio by counting the teeth. Center spline specs, gear width, etc. could be measured off the regular gears. Someone here may have specs, spares or a portal open for some reason. As for the price, once you know the tooth count start calling around for custom machine shops for prices. If you lucky they may turn out to be a commonly available gears.

Good luck!

Cheers, Clive

No they are making them. Definitely not common. It turns out the ratio is the same, just the tooth count is different due to the new gears being thicker/bigger teeth. Overall diameter is the same of course.

They are also making tougher CV joints, disc brakes and tranny adapters for a popular US model with overdrive.

I did it :D
Should be the original ratio.
The big gear has 33 teeth. Same as original.
I found a picture of mine, when I changed wheel bearings.
The small one has 16 teeth. So gear ratio is 2.06 as original.

Can I get the outside diameter of those 2 gears? I have access to a CNC and I want to see if I can recreate them.

Thanks,

Ben
