Hey Per,
yes that means `` Överväxel`` .
It is easier to ride on long distance rides.
I put it in my L 36 from 1967, and my wife said I shoudn´t do it because she is not riding the Scania to be quick on the road.... Well I changed the gearbox anyway , to find out what´s gonna happen... .
The good thing was the scania had also the 2 speed Backaxle, so we were able to go easily 70 km/h on the lower bit, and max 120-125 km/h on the upper gearing in the backaxle.
It really was a lot of Fun.
My wife took the Scania after I changed the gearbox and drove it on the Autobahn..... I really had my troubles to get after her. !!! Ladies ..
Oh, those gearboxes are sometimes put in normal small Magirus Deutz trucks. The mounted it sideways /on the side, not uprite like it is mounted in the scania. But you only take the top of the gearbox and change it over from the gearbox that was sitting in the scania. No trouble at all. It is all the same with ZF gearboxes.
