Scania introduces G38 to team up with its 770 V8

G38 is the latest and final iteration of the G-series gearboxes that was first intro-duced in 2019 (with the G33). It is tailor-made for handling the massive torque that Scania’s 770 hp V8 is producing. Despite being able to handle up to 3,800 Nm of torque, it features exactly the same dimensions and weight as the G33. So, how is it made? 

“It is basically about metallurgy, choosing more extreme steel qualities and applying  technologies such as cog polishing and shot peening for increasing the hardening and the durability of certain vital components” says Mats Henriksson, Development Engineer at Scania R&D. “We have also added extra oil channels for the most crucial parts, but that is all – the basic design of the G-series is very sturdy in itself”.  

The G-series gearboxes are typically 60-70 kg lighter than the gearboxes they are replacing, mainly due to the all-aluminium housings and smaller overall dimen-sions. Another key achievement is lowered noise, a prerequisite for meeting future regulations. The gearshifts on these automated manual gearboxes are made by pneumatic actuators. By using shaft brakes, Scania’s engineers have been able to reduce the number of synchronisations, space that is used for wider cogs instead.

“The G-series and its features was something of a revolution at the time of the intro-duction, and it still is if you ask me”, says Bo Eriksson, Product Manager, Scania Trucks. “It offers all the customers values you can ask for while at the same time being flexible and fit for a broad palette of applications and operations of the kind where a lot of horsepower and torque are involved. Heavy-haulage tractors for in-stance will definitely benefit from the G38. It is the ultimate addition when it comes to well-balanced performance steps in the Scania modular system”. Read more
