The Build – Part 5
In this step we’ll be attaching the motor mount assembly, installing the front and rear diffs as well as the single serpentine drive belt. Tamiya has designed the TA07 Pro to allow three different mounting positions for the motor mount; we’ll be using the furthest back position to start.
The TA07 Pro uses a single drive belt that winds its way through a series of pulleys. When assembling, take extra care not to crimp the belt as this will certainly cause some major drive issues.
Start off this step by test fitting the motor mount to the chassis. You want the plastic mounts attached to the aluminum plate to be ‘square’ with the chassis. Once you’re happy with the mounts, attach the assembly to the chassis.
Wrap the belt around the rear diff and slide it into the rear bulkhead. Continue to feed the belt around the spur gear and pulleys as shown, being careful not to crimp it.
Attach the rear bulkhead cap. You can, at this time, tighten the bulkhead screws under the chassis as well.
Wrap the belt around the front diff and slide it into the front bulkhead. Attach the front bulkhead cap. You can also tighten these bulkhead screws from under the chassis as well.
That was a pretty easy step, right? The manual-suggested tension is a good starting point, but you can adjust it with one or both of the tensioners on the motor plate. Next up – the steering!
