Tools and Equipment for Engine Valve Refacing

This page lists core tools, accessories, and consumables that support accurate, repeatable valve refacing. Start with the essential setup, then add measuring and process-control tools to improve consistency and throughput.

Featured Machine

Essential Setup Tools

  • Work light (shadow-free)
    Improves visual inspection of face finish and edge definition.

  • Coolant and compatible grinding oil
    Controls temperature, improves finish, and extends wheel life.

  • Dressing tool and diamond(s)
    Keeps the wheel sharp, flat, and true for consistent geometry and finish.

  • Wheel flange and wrench set
    For safe, repeatable wheel changes and balancing.

  • Machine stand or rigid bench
    Stable mounting reduces vibration and chatter.

Grinding Wheels and Consumables

  • 7" vitrified or ceramic wheels (coarse to fine)
    Select grit/bond for material and finish requirements.

  • Wheel cleaning sticks and dressing diamonds
    Maintain cutting action and surface quality.

  • Coolant/oil filters and replacement media
    Keeps abrasive fines out of the system to protect finish.

  • Splash guards and pads
    Helps contain coolant and debris, improving safety and cleanliness.

Measuring and Inspection

  • Dial indicator with magnetic base
    Check runout and concentricity on stems and faces.

  • Valve micrometer or calipers
    Measure head diameter, stem diameter, and length.

  • Surface finish comparator (optional)
    Visually correlate finish to known standards.

  • Optical comparator or strong loupe
    Inspect margin, edge sharpness, and finish quality.

  • Seat width gauge (if seat work is performed)
    Verify sealing width after refacing and cutting.

Workholding and Geometry

  • Collet sets or adapters (for legacy chucks)
    Ensure proper stem engagement if not using a six-ball system.

  • Small valve collet kit
    Improves control for sub-5 mm stems when needed.

  • Angle reference gauge
    Confirms face angle settings during setup.

  • Rocker arm refacing attachment
    Extends capability for shaft-mounted rocker service.

Process Control and Maintenance

  • Trueing/dressing schedule card
    Standardize when to dress to keep results consistent.

  • Preventive maintenance checklist
    Lubrication, coolant changes, and inspection intervals.

  • Spare belts and hoses
    Minimize downtime with on-hand wear parts.

  • Coolant pump (external/heavy-duty)
    Increases flow and reliability for high-throughput shops.

Safety

  • Eye and hearing protection
    Mandatory for grinding operations.

  • Nitrile gloves and shop towels
    Clean handling during inspection and assembly.

  • Proper ventilation or mist collection
    Improves air quality and visibility.
