At 140 km/h the difference is exactely 500 rpm with the same calculation.

My rev limiter is set to 7200 rpm ... = 303,5 km/h .....

The part numbers are 7757955 and 7757956.

You just unscrew the end cover of the gearbox and you find the 5:th gear just in front of you. The gears are locked to the shafts by a nut (don't know the size) so unscrew the nut on each shaft, remove the gears and put in the new ones. No new gasket is needed since "silicon glue" is used from factory.

Happy New Gear
