Hi guys can anyone tell me how many teeth the crown and pinion gear should have for a 3.54 ratio.

Many thanks

I did this in Excel, so at a guess it's 13:46 as it's only .02 out. 13/46 = 3.538 = 3.54
3.54 8 28.32
3.54 9 31.86
3.54 10 35.4
3.54 11 38.94
3.54 12 42.48
3.54 13 46.02
3.54 14 49.56
3.54 15 53.1
3.54 16 56.64
3.54 17 60.18
3.54 18 63.72
3.54 19 67.26
3.54 20 70.8
3.54 21 74.34

I've got one at home ready to go into my axle, I'll have a look tonight

These are all the ford english crownwheel & pinion sizes I know.

Ford Diff:’s
3.54 = 11/39
3.777:1=9/34
3.89:1=9/35
3.9:1=10/39
4.125:1=8/33

Hope that help's.

Cheers guys ill go and count some teeth now.

Oh YES

Looks like I may have for once lucked out I have just counted the teeth on my pinion and it has 11! RESULT!!!!

Cheers for the info.

Hi are you shure it's not stamped on the outer face of the crownweel or on the end of the pinion.

Unusual if you can not see either markings.
