TB-03 front oneway sleeve for servicing

This 7075 aluminium front oneway tube is a replacement service part for the TAMIYA TB-03 chassis, model TB03-09. It functions as a serviceable element in the front drivetrain where oneway rotation is needed, aimed at hobbyists working on tune-ups and repairs.

Machined from 7075 aluminium, the tube meets common hop-up tolerances for alloy parts. The sleeve positions inside the front differential or oneway housing and interfaces with bearings and shafts to provide a stable, wear-resistant surface without altering primary suspension geometry.

Fitment tips: remove the original tube carefully, check bearing fitment and radial play before final assembly, and use thread locker only on specified fasteners. This component improves durability and simplifies front drivetrain servicing during setup routines.

Specifications

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

Ideal when renewing worn sleeves or refurbishing the front oneway assembly; ensure bearings and shafts are matched to retain correct clearance.

Is this a drop-in replacement for TB-03?

Designed for TB-03, it should fit directly in most front housings, though you should inspect bearing seating and shaft alignment during installation.

How does the sleeve affect wear?

Using a harder 7075 sleeve reduces wear on the contact surfaces and helps maintain consistent drivetrain clearances over time.

Should I change bearings when installing?

Inspect bearings for play; replace any with signs of wear to ensure proper seating and avoid premature failure after installing the new tube.

Will this alter handling?

The sleeve is a service component and does not directly change suspension geometry; any handling shifts are minor and come from drivetrain feel rather than suspension changes.
