Team Associated TC6.1 Build – Part 9 – Spur Gear and Belts

The Build – Part 9
In this step we’ll assemble the spur gear to the center hub as well as attach the front and rear belts. We will also be installing the front spool and rear diff.

Build Notes:
Not to much to say with this step other than to have a little loctite handy for a few of the steps.

Start by sandwiching the 87T spur gear inbetween the spur gear hub and clamping ring. Only 3 3x5mm screws are required and will need a dab of loctite.

Next, press the 20T pullies onto the flanges on the spur gear hub. They should ‘snap’ into place.

We are now going to assemble the spur gear shaft. Start pressing a bearing into each side of the spur gear assembly. The flange of the bearing should be on the outside. Take the spur gear shaft and snap an E-clip in the groove at one end of it. Slide a shim into place and then slide the gear shaft through the bearings on the spur gear assembly. Slide the second shim into place and snap the final E-clip into the groove.

Untwirl both belts (I think untwirl is a word)…

…and wrap them around the spur gear assembly. Drop the spur gear assembly inbetween the bulkheads on the chassis and install the 2.5x8mm screws to secure it in place. Don’t forget a dab of loctite. Also note the belts in the picture; verify they are on the correct side of the spur gear assembly. Take the rear diff and, after wrapping the short belt around it, slide it into place within the rear bulkhead halves.

Take the front belt and wrap it around the spool. Drop the spool into place between the front bulkheads. Pay attention to which side of the belt the steering assembly goes on.
