Motorised Rescue Truck
This model can be built using a 12211 K'NEX 50-model set or a 13419 K'NEX 70-model set plus a 22722 K'NEX Battery motor Green.
First, assemble a non-motorised version of the Rescue Truck, using the instructions in the K'NEX 70-model set .
Push a yellow rod right through your motor.
Then add white connectors, blue spacers and tan clips facing outwards, as shown in the photo.
Fit the wheels, so that the lugs on the tan-coloured interlocking clips fit into the small holes in each wheel.
Finally, fit the new rear wheel assembly back into your Rescue Truck model, and test it by switching on the motor.
