TT01 differential cup

The TT01 differential cup is a key part for regaining grip and traction in your Tamiya RC model.

The TT01 differential cup, with reference YETT133BU, is a transmission component specifically designed for the Tamiya TT-01 chassis. Its function is to house the differential and allow each wheel to rotate at different speeds in corners, improving the overall behaviour of the vehicle both in recreational use and club competition.

Function and performance

The differential cup is the element that encases and protects the differential gears, transmitting the motor torque to the wheels with the highest possible efficiency. In the Tamiya TT-01 chassis, a well-maintained cup is essential to avoid traction loss, abnormal noises, or erratic behaviour during driving. Its replacement is necessary when the original shows signs of wear, impacts, or cracks after intense running sessions.

Compatibility

This differential cup is intended for the Tamiya TT-01 chassis and its directly compatible variants. Before placing your order, we recommend checking that your specific version of the chassis accepts this component, as there are different generations and revisions of the TT-01 over the years.

Assembly and preparation

The assembly process is straightforward for any enthusiast with basic experience in RC model maintenance. It is recommended to:

• Thoroughly clean the housing area before installing the new cup.
• Check the condition of the differential gears before assembly to take advantage of the opening.
• Apply the appropriate grease for differentials according to the manufacturer's instructions.
• Correctly tighten the securing screws to avoid play that could generate vibration or noise.

Common mistakes

• Installing the cup without first checking the condition of the satellites and the central pinion of the differential, which can lead to premature failure of the new part.
• Not using the appropriate grease, resulting in accelerated wear.
• Over-tightening the closing screws, which can deform the cup and lock the differential.

Frequently asked questions

Which chassis is this differential cup compatible with?

It is designed for the Tamiya TT-01 chassis and its compatible versions. We recommend checking your model's documentation to confirm the exact compatibility with your chassis variant.

When should I replace the differential cup?

It is advisable to change the cup when symptoms such as abnormal noises in the transmission, loss of traction on one or both wheels of the affected axle, or visible wear, cracks, or deformations in the original part appear.

Do I need special tools for the assembly?

The assembly does not require specialized tools beyond a standard screwdriver set for RC models. However, having a small syringe to apply grease greatly facilitates the process.

Should I also change the differential gears when replacing the cup?

It is not mandatory, but it is highly recommended to take advantage of the disassembly to check the condition of all internal differential elements and replace those showing excessive wear.

The TT01 differential cup (ref. YETT133BU) is a replacement transmission part for the Tamiya TT-01 RC chassis, ensuring smooth and efficient power delivery to the wheels. Essential for maintaining correct differential function, this component is a must-have spare for TT-01 owners looking to keep their car performing at its best, whether for club racing or recreational driving.
