Top line looks like the gear ratio. What are you trying to figure out?

If car with first axle would go 100 km /h,
how much would it go with second and with third?

And how to check if axle is in good condition?

All the 307d vans are going to go faster than 100kph. My 307d easily did 65mph and it was very heavy. My 409d topped out around 68mph I think and it had the lowest axle ratio possible in the small vans.

The 4.4 and the 4.375 are not going to be significantly different. The 4.9 is going to have a lower top speed, but again the difference is not going to be huge. I'm guessing maybe 5kph less or something like that.

In answer to your question, the last two differentials will produce a higher top speed than the first if I'm reading that top line on the plates correctly.

Thank you.

do You know maybe specifications for gearbox,
It is that i have now gearbox for om601 motor. (around 1992) And this is much faster. (i can not tell how much the difference in km/h is because after replacing motor and gearbox my velocity clock does not work any more. Maybe i will open i new post to clear it.)
Before i had gearbox of om616 (dated 1986)

i have find out in my "car book"

HL 0/1-1,7
HL 0/2-2,2
HL 0/3-3,3

but i do not know what it mean.

So i can be sure that axles are equal in general. The difference is just in gear ratio?
