Tamiya 42269 TRF 04 Hard Coat 39T pinion for reliable gear engagement

The Tamiya 42269 TRF 04 Hard Coat Aluminum Pinion Gear 39T offers a lightweight, treated aluminium option for hobbyists seeking consistent drivetrain behaviour. The hard coat reduces surface friction and helps the gear resist wear over time.

Key features and compatibility notes

Forged from aluminium and finished with a hard coating, this pinion aims to provide longevity while keeping rotating mass low. It is compatible with Tamiya models that use 04 Module gears, making it an easy swap for many kits.

Quick installation and what is included

Supplied with a 3mm grub screw, the pinion is straightforward to install on standard shafts. Check gear mesh carefully after fitment and recheck after a short run to confirm secure mounting and smooth engagement.

Can I use this pinion on vintage Tamiya kits?

If the vintage kit uses 04 Module gears and the shaft size is compatible, the pinion will fit, though wear on older spurs should be checked first.

What maintenance keeps the pinion running well?

Regularly inspect mesh, clean debris, and apply a light smear of gear lubricant to mating teeth to extend service life.

Should I replace the spur when fitting a new pinion?

Inspect the spur for wear; if teeth show pitting or uneven wear, replace the spur to ensure reliable mesh and reduce noise.

Is the supplied grub screw metric or imperial?

The included grub screw is 3mm metric, which suits the standard pinion shaft sizes used by Tamiya.
