* Solder a pair of leads to each motor. You might find it helpful to make a small bend at the tip of each lead to hook into the hole in the motor lead tab to hold it in place for soldering. '''Warning:''' holding the soldering iron against the motor lead for more than a few seconds can start to damage the motor brushes, so try to be reasonably quick/efficient with this soldering; if the first attempt does not go well, remove the soldering iron and let the motor cool for a few seconds before trying again.

Each motor’s positive terminal is indicated by a plus sign (+) in the black plastic end of the motor, visible at the bottom of the picture above. The motors should be soldered into the shield with the positive terminal closest to the front, so you should attach the leads to allow the motors to be oriented this way. (However, don’t worry if you accidentally get the orientation of one or both motors wrong. You can later compensate for it in software with our [[Pololu-Zumo-Shield-Arduino-bibliotheque-Zumo|ZumoMotors library]].)

* Place the motors into the channel in the front of the chassis, aligning the gearbox with the grooves in the channel. The front plate of the gearbox should be even with the edge of the chassis.

{{ambox|text=To assemble the chassis with the Zumo Shield, you should use the two-piece acrylic spacer plate that is included with the shield. You will not need the one-piece mounting plate that is included with the Zumo chassis.}}
* Place an M3 nut in each of the two side slots near the rear of the chassis. The slots are sized so that nuts will not be able to rotate within them. (These nuts will be used to mount the idler sprockets later.)
* If you want, peel the protective paper masking off both sides of the acrylic spacer plate pieces (the spacer plates in our pictures show what they will look like with the masking peeled off). Alternatively, you can leave the masking on for additional thickness. If you leave the masking on, it will be mostly concealed when the robot is fully assembled.
* Cover the chassis and motors with the spacer plate pieces and then the Zumo shield. The holes in the spacer plate should line up with the through-holes in the shield resting on top of it, and the motor leads should be aligned so they pass through the slots in the spacer as shown in the picture below. There is only one correct orientation for these plates. (The plate consists of two separate pieces to make it possible to disassemble the Zumo without having to desolder the motors or battery terminals.)
