Off-Highway Series Transmissions


Off-Highway Series

The 5000, 6000, 8000, and 9000 Off-Highway Series transmissions are used in applications requiring 298 kW to 1678 kW (400 to 2250 horsepower) engines. Applications are diverse and include oil-field pumping and fracturing units, off-highway trucks, agricultural tractors, and winch units such as those on derricks and cranes.

5000, 6000, 8000, 9000 Series transmissions have a torque converter and lockup clutch, planetary gear sets, and hydraulic clutches. Further needs are met by optional equipment which may include a hydraulic retarder, parking brake, power takeoff (at various locations), or transfer gear housing (dropbox).

Hydraulic or electronic controls are available on the 5000 and 6000 Series. The 8000 and 9000 Series transmissions utilize manual or automatic electronic controls.
