850 Series

AIDCO Test Systems Model 850 Hydraulic Test Center is a versatile test stand designed for testing heavy-duty off-highway power shift and automatic transmissions. In addition to automatic transmissions testing, the AIDCO Model 850 is capable of testing various hydraulic system components. Components include, but are not limited to, hydraulic cylinders, valves, torque converters, closed or open loop pumps and motors all from the same unit.

Capable of detecting shift points and mechanical binding, identifying vibrations, diagnosing and locating leaks, and measuring pressure and flow, clutch leakage and output torque, the AIDCO Model 850 Hydraulic Test Center is one of the most comprehensive hydraulic testing tools on the market.

**Available as the 850M (Military Series) with dual-current load absorption units for cross-drive testing capabilities.

Features

• A closed-loop hydrostatic drive system
  inputs rotary power to the component being tested.
• 200 or 300 HP options available.
• Hydraulic drive motor power lift facilitates
  vertical maneuvering to align the drive shaft with the component under test.

Benefits

• Drive speed is controlled from a single
  potentiometer for simplified operator control.
• Provides closed loop speed, flow, and load
  control to the component under test.
• Twelve pressure taps in conjunction with
  liquid-filled pressure gauges monitor
  pressures within the component under test.
