Service and Replace the FF-01 Rear Gear Case

The Tamiya 50639 Rear Gear Case is a replacement housing purpose-built for the FF-01 front wheel drive touring car. It is also compatible with TA-01 and TA-02 chassis, making it a useful spare for anyone maintaining a classic touring setup. The unit helps keep gear alignment consistent and reduces the chance of drivetrain issues from a tired case.

Key Points About the Gear Case

Compatibility: Fits FF-01 and is suitable for TA-01 and TA-02 applications where the mounting points match.
Durability: Intended to stand up to regular on-road use and normal club racing demands.
Functionality: Helps maintain smooth drivetrain performance by ensuring correct gear spacing.

Is the Tamiya 50639 suitable for older TA-02 kits?

Yes, where the TA-02 uses the same rear mount pattern it will fit, but confirm diff and shaft positions to ensure correct assembly.

Can this be used to fix play in the rear end?

Replacing a worn or cracked case with the 50639 can reduce unwanted movement and restore tighter gear engagement, improving rear end feel.

Should I change the gears when fitting this case?

It is good practice to inspect gears and bearings and replace any worn items during the swap to ensure the new case delivers reliable operation.
