In summer 2025 MSG Equipment discounted the MS503N, which flushes hydraulic power steering systems and tests the rack and pump.
In July and August 2025 MSG Equipment offered a discount on the MS503N (230 V) bench for hydraulic power steering diagnostics and flushing. The offer ended at the close of August 2025.
The MS503N flushes the steering system during fluid replacement, fully removing old fluid that has lost its properties and carries mechanical particles from vehicle use.
The bench can also be connected to the vehicle to check some parameters of the steering rack and/or pump while installed, using readings from its gauges, and it can test racks that have been removed from the car.
