For over twenty years, vehicles have been equipped with Electric Power Steering (EPS), and currently most passenger cars feature EPS steering systems. When EPS steering rack malfunctions occur, steering racks are typically repaired rather than replaced due to cost considerations. Therefore, Electric Power Steering repair services are in considerable demand.

EPS repair is a complex process that only experienced mechanics can handle. Professional expertise plays a major role, but regardless of mechanic skill level, specialized professional tools must be available. Repair speed and results depend on tool quality and reliability.

Specialized Keys for Electric Power Steering (EPS) Repair

MSG Equipment offers specialized tools for repair and mechanical adjustment of EPS components for all vehicle makes and models. Our catalog features keys and fixtures that ensure EPS component integrity during installation and removal procedures.

Main Types of Electric Power Steering Specialty Tools:

  • Straight crown keys (SC) - used for removing or installing worm gear mechanism lower nuts and steering rack lateral adjustment nuts
  • External polygon keys (PO) - used for working with worm gear mechanism upper nuts
  • Pin keys (P) - designed for steering rack support bushing removal and installation
  • External star keys (OS) and internal star keys (IS) - used for lateral adjustment nut regulation and worm gear mechanism nut removal
  • Sun keys (S) - used for ball screw coupling pulley fixation when loosening bearing retaining nuts

Universal Tools for Electric Power Steering Service

In addition to specialized keys, quality EPS steering rack repair requires universal fixtures:

  • Torque sensor pullers from worm shafts - ensure rack and sensor integrity when removing rotor position sensors
  • Electric motor pulley installation/removal fixture sets - enable work without damaging assembly components
  • Ball screw coupling pulley adapters - protect pulleys from damage during removal

Using specialized EPS repair tools significantly simplifies steering rack disassembly/assembly processes and minimizes component damage risk. Each tool is designed considering specific EPS steering rack model characteristics.

Important Specialty Tool Usage Guidelines

When working with specialized EPS repair tools, the following rules must be observed:

  • Avoid impact loading on tools
  • Do not heat tools above 250°C

Proper selection and application of Electric Power Steering specialty tools enables quality repairs in minimal time while preserving all mechanism components for continued use.
