850 Series – TRANSMISSION AND HYDRAULIC COMPONENT TEST STAND

Category:

Description

A versatile test stand designed for testing heavy-duty off-highway hydraulic components, the 850 Hydraulic Test Center features some of the most advanced technology on the market today. Designed for complete hydraulic pump, motor, and transmission testing, the 850 is much more than a standard transmission test bench.

The 850 provides a durable and reliable platform for performance testing transmissions, torque converters, gear pumps, vane pumps, hydrostatic pumps and hydraulic motors, cylinders, and valves. Performance testing results in reduced operating costs due to rebuilding error and possibility of critical failure in the field; equipment dealers can realize more profitable maintenance contracts and increased customer satisfaction. Additionally, the 850 features an independent closed loop hydrostatic drive for a contamination free drive system, independent constant display digital instrumentation for easy readability, and industrial grade glycerin filled pressure gauges.

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