Q: What is the material specification for part number TO 00591-38903-81?
A: The TO 00591-38903-81 steering roller race is manufactured from hardened bearing steel. This material provides high load capacity and wear resistance in the steering assembly roller race application, which sustains continuous lateral and rotational forces during truck operation.

Q: What equipment does the TO 00591-38903-81 steering roller race fit?
A: This part is a Toyota OEM steering roller race designed for electric lift trucks. It is compatible with Toyota electric forklifts and reach trucks that use this specific steering assembly configuration. Verify your truck model and serial range match this OEM part number before ordering.

A: No cross-reference, superseded, or equivalent part numbers are documented in official or approved Toyota distributor sources. This is a Toyota-specific OEM part. Use the exact part number TO 00591-38903-81 for accurate ordering and fitment.

Q: How long does a steering roller race typically last in service?
A: Hardened bearing steel roller races in steering assemblies typically last 5000 to 8000 operating hours under normal conditions. Lifespan depends on load, operator technique, surface condition maintenance, and steering assembly alignment. Worn races cause increased steering effort or play in the steering column.

Q: What symptoms indicate the steering roller race needs replacement?
A: Worn or failed steering roller races produce grinding or roughness when turning the steering wheel, increased steering effort, or audible clicking during full turns. Inspect the race for spalling, pitting, or surface damage. Replace immediately if damage is visible to prevent steering assembly failure.
