Torque converter

Power separating, hydraulic-mechanic drive, single stage torque converter is used in SD8 elevale sprocket bulldozer.

Transmission assembly

It integrates center drive, transmission and speed changing control valve into one component. It can be assembled or disassembled as assembly or as a part. It is very convenient to service. Transmission is multi-stage planetary drive to realize modular assembling and disassembling. Gear the shift can be changed among 1st gear, 2nd gear, 3rd gear forward or reverse rapidly, through multi-functional control valve.
