Triad slipper clutch B-MAX2 installation instructions

To use the Triad slipper clutch on the Yokomo B-MAX2 you will also require Avid RC's Triad Kyosho aluminium top shaft (AV1020-TOP-KYO).
Let me guide you through the installation of the "AV1020-MOD/STK Triad slipper clutch"

Required parts:
• AV1020-MOD/STK (according to modified or stock motor) Triad slipper clutch
• AV1020-TOP-KYO Triad Kyosho aluminium top shaft
• 5 mm internal diameter bushing and shims
• M3 low-profile nylon lock nut

This picture shows the standard B-MAX2 top shaft on the top, and the AV1020-TOP-KYO top shaft on the bottom.
Both top shaft pinions have the same number of teeth, and the size of the bearing in the gearbox (1050) is also the same.

Slipper mounting hardware on the B-MAX2 is metric, whereas the Triad slipper originally was designed for cars with imperial/SAE hardware
Mounting the Triad directly on the standard slipper shaft is not possible, the AV1020-TOP-KYO top shaft must be used instead

As the AV1020-TOP-KYO top shaft was designed for another gearbox, shimming the shaft with a bushing and shims of 5 mm internal diameter is required to optimize the mounting position.
Approximately 3.8 mm had to be covered with a combination of bushing and shims on the side of the motor plate, and another 0.5 mm were required on the gear side in our case.
Please adjust shimming to the individual tolerances of your bearings and gearbox to ensure the top shaft rotates lightly.
Adjust the position of the top shaft so that the top shaft pinion does not interfere with the gearbox housing.

To assemble and install the Triad slipper on your modified B-Max2 transmission follow the Triad slipper installation instructions for the Associated B4.1.

After completing the installation of the Triad, check again whether everything in the gearbox rotates smoothly.

On the AV1020-TOP-KYO top shaft, the threaded part is smaller in size than on the original M4-sized B-Max2 top shaft. In addition, the threaded part is shorter. We recommend using a generic low-profile M3 nylon lock nut to prevent the nut from coming loose during operation.
