Team Associated RC8.2 Build – Part 7 – Center Differential

The Build – Part 7
The center differential assembly is a pretty straightforward step. Since we already built the center diff, it’s must a matter of assembling the mount and attaching it to the chassis.

Build Notes:
This is a pretty simple step, but pay close attention to the direction of some of the plastic parts. Correct orientation is important.

Attach the brake pads to the plastic mount. Check both sides of the stamped pads. You will notice the edges are rounded on one side and slightly sharp on the other. Assemble so the rounded side is FACING the brake disc. Build two of these assemblies.

The instructions call for a 4.5mm gap between the pads. This is a good place to start, but I ended up tightening it up to about 4.3mm.

Slide the pads onto your built center diff (pay attention to the keyed outdrives) and install the upper and lower bulkhead halves. Note the direction of the bearing flanges on the bulkheads.

Your completed setup should look like this.

Set the brake cams into place, noting the location of the flat spot. It should be facing the brake pads.

Slide the center diff top plate over the brake cams and screw into place. Do not fully tighten the screws yet, we will do that in a following step.

Your completed assmebly. Make sure the diff spins freely and the brakes are not bound up.

Set the center diff assembly onto the chassis, key the dogbones into the outdrives and swivel into position. Note the direction of the assembly.

Insert and tighten the 4x12mm screws. Now tighten the top plate screws. No need to gorilla these screws; tighten until snug.
