Transmissions
JCB transmissions
Compact transmissions. High performance.
Our compact transmissions with torque converter drive are designed to provide uninterrupted power using electrohydraulic controls with the option of multi-plate clutch packs, for smooth reversing and gear shifting.
With optional 2WD and 4WD transmission, pump drive, internal multi-plate oil immersed park brake, lock up torque converter and proven reliability from both test bed and in the field, these transmissions offer high performance in the worst of operating conditions. The JCB powershift transmission also transmits constant mesh gearing and multi-plate clutch packs for maximum reliability.
Also included within this compact transmission line is single speed transmission, remotely mounted transfer boxes and wheel-end drop boxes, both of which utilise helical gears directly supported by bearing mounts for extremely quiet running.
