"Remember ZF’s rating is for the warranty period { 100,000 km }, their durability testing is run at the full rating { 600 nm } simulating the estimated gear changes that the box will make in 100,000 kmsSo in the real world peak loading can be enormously higher. Given a billet input shaft but standard plates and clutches. That's a torque loading of 1180 nm. Of course the life expectancy is greatly reduced from 100,000 kms at this torque level."
Letet opp litt info om ZF 6HP26 kassen.
