Hydraulic Power Steering (HPS) Diagnostic and Repair Equipment
Hydraulic Power Steering (HPS) systems provide comfortable vehicle control and enhance road safety. The need for regular diagnostics and timely maintenance of hydraulic power steering systems is dictated by their direct impact on vehicle handling. MSG Equipment develops and manufactures professional power steering diagnostic tools for testing and repairing HPS system components, allowing for identification and elimination of malfunctions at early stages.
Types of Hydraulic Power Steering Diagnostic and Repair Equipment
Our range of diagnostic and repair equipment for hydraulic power steering systems includes various technical solutions:
- Hydraulic steering rack testing machines for power steering racks
- Power steering system testers for on-vehicle diagnostics without component removal
- Steering system flush equipment for hydraulic steering systems
- Power steering pump test stands
- Hydraulic steering rack load testers
- Steering rack shaft restoration machines
- Auxiliary power steering repair tools
Functional Capabilities of Hydraulic Power Steering Testing Equipment
Hydraulic steering rack testing machines simulate rack operation as installed in the vehicle. This allows detection of malfunctions such as leakage, wear of sealing cuffs, damage to the housing, and Teflon rings. The equipment creates working pressure up to 140 bar and provides working fluid flow up to 5.9 l/min, matching the real operating conditions of power steering systems.
Power steering system testers check the functionality of hydraulic system elements without removing them from the vehicle. They connect to the high-pressure line and measure both pressure and flow of the working fluid in various operating modes. Portable testers enable technicians to determine the pump and steering rack condition, identifying distributor wear and ring wear in the power cylinder housing.
Steering system flush equipment ensures complete cleaning of the system from old fluid that has lost its performance properties and contains mechanical impurities. These stands also allow checking the functionality of both vehicle-installed and dismounted HPS system components.
Steering rack shaft restoration machines provide uniform polishing of the shaft surface, restoring functionality to parts that may be difficult to replace. Shaft restoration significantly reduces repair costs compared to replacing the entire steering rack, making the service economically attractive for auto service customers.
Technical Capabilities of Hydraulic Power Steering Diagnostic Equipment
Professional power steering diagnostic tools offer a wide range of technical capabilities:
- Diagnostics of all types of hydraulic steering racks and power steering pumps
- Use of special ATF DEXRON II working fluid
- Working fluid tank capacity from 18 to 22 liters
- Measurement of working fluid pressure in the range from 0 to 250 bar
- Control of fluid flow in the system from 0 to 19 l/min
- Adjustment of maximum working fluid pressure in the steering rack
- Measurement of working fluid temperature from 0 to 100°C
- Simulation of steering rack load when testing power steering pumps
- Adjustment of pump pulley rotation speed from 0 to 1500 rpm
- Smooth regulation of drive rotation speed
- Selection of drive rotation direction when testing pumps
- Compact design of certain models for mobile use
Hydraulic Steering Rack Load Testing Equipment
The hydraulic steering rack load tester provides resistance to rack shaft movement, simulating the load from turning the vehicle's wheels. These mechanisms reveal malfunctions that only manifest under load: leakage in the distributor, condition of the hydraulic cylinder's central seal, and wear of the housing in the middle part of the hydraulic cylinder.
Operating from compressed air pneumatic lines, these mechanisms provide maximum load on the shaft up to 250 kg at operating air pressure from 2 to 10 bar. When used in combination with steering rack diagnostic equipment, they significantly increase the reliability of results and help identify hidden defects.
Auxiliary Power Steering Repair Tools
For quality repair of hydraulic power steering components, specialized tools and devices are essential. Pneumatic vises quickly secure cylindrical objects with diameters from 35 to 85 mm with a clamping force of up to 1400 Newtons, which is necessary when disassembling and assembling hydraulic power steering racks. These vises are controlled using a pneumatic distributor, improving both convenience and productivity during repair work.
This auxiliary equipment forms an integral part of the repair process, ensuring reliable fixation of assemblies during maintenance. This significantly improves the quality and speed of work while reducing the risk of damage to expensive components.
Application Areas of Hydraulic Power Steering Diagnostic Equipment
Specialized hydraulic steering service equipment is in demand across various areas of automotive service:
- Multi-profile auto service centers servicing vehicles with hydraulic power steering
- Specialized workshops for steering system repairs
- Dealerships performing warranty service
- Manufacturers and rebuilders of steering racks and HPS pumps
- Service stations with steering system repair departments
Recommendations for Selecting and Purchasing Hydraulic Power Steering Equipment
When selecting diagnostic equipment for hydraulic power steering systems, consider the specifics of your auto service center, including the volume and nature of work performed. For basic HPS system diagnostics, portable testers are suitable as they determine the general condition of the hydraulic system without dismantling components.
For a full-fledged repair department, the optimal solution is a comprehensive set of equipment, including test benches for steering racks and pumps, load testing mechanisms, and hydraulic system flushing equipment. This enables you to provide a complete service cycle for HPS system components.
