12JS series gearbox (manual)


1) Two countershafts,  power redistribution, smaller axial size with the same torque;
2) Improved design of important gears, applicability in conditions of varying complexity;
3) Increased center-to-center distance of the demultiplicator countershafts, enhanced load capacity;
4) B10 resource up to 1.2 million kilometers, world leading position in reliability;
5) Optionally completed with gear shift amplifier for optimized handling;
6) Optionally, helical gears are used to achieve smoother engagement and increase the comfort of the entire vehicle;
7) Various speed ratios, optimal matching, production entirely from aluminum alloy allow for a weight reduction of 85-100 kg;
8) When installed on dump trucks, special cars, construction cars, etc. can be equipped with a power takeoff (PTO), retarder.
