890 Wind-Up Motor

890 Wind-Up Motor is a Universal Building Set released in 1981. It contained 10 pieces. These are: a yellow wind-up motor, a black 2x4 axle block, four red wheels and two red wind-up keys.
== Notes ==
* Replacement keys (they are the part that breaks first) have been sold in the kits 1205 2 Keys for wind-up motor and 5004 Motor Keys.
* The shape of the junction of the key with the motor is based on a square section on the motor, but the key has a star section (combination of two squares rotated of 45 degrees) to allow easier insertion, every 45 degrees.
* It is the same as 895 Wind-Up Motor.
