Precision front oneway sleeve for TB-03

This 7075 aluminium front oneway tube is specified as a service replacement for the TAMIYA TB-03 chassis, model TB03-09. The component is intended to provide a durable bearing surface inside the front differential or oneway housing, supporting predictable oneway engagement during tuning and maintenance.

Manufactured from 7075 aluminium with controlled machining tolerances, the sleeve is designed to interface with standard TB-03 bearings and drive shafts. The goal is to supply a stable, wear-resistant bore that maintains drivetrain clearances without modifying suspension geometry or primary alignment.

Recommended installation procedure: remove the existing sleeve, inspect bearing seat diameters and axial endplay, press or drive bearings to the correct depth, and apply thread locker only to fasteners that require it. This part is targeted at enthusiasts and racers who perform stepwise drivetrain tuning and require reliable, repeatable service parts.

Specifications

  • Item: Front Oneway Tube
  • Material: 7075 aluminium
  • Model Number: TB03-09
  • Compatibility: Tamiya TB-03

Use this precision sleeve when renewing worn front oneway components; confirm bearing and shaft tolerances to sustain designed drivetrain geometry and function.

What tolerances should I check when fitting?

Measure bearing seat diameters and axial endplay; ensure bearings press to the specified depth and that the shaft engages without excessive runout.

How does material choice affect drivetrain behaviour?

7075 aluminium improves wear resistance and dimensional stability compared with softer alloys, helping maintain consistent drivetrain clearances under load.

Any special installation tools recommended?

A bearing press or drift and calibrated hex drivers for retaining hardware are recommended to ensure accurate seating and repeatable assembly results.

Is this suitable for competition setups?

Yes, it is a service-level upgrade intended to give consistent fitment and longevity for competitive maintenance cycles rather than change setup geometry.
