Hi Psygorn (Drillbit),
The picture is very blurred, but it is the very old motor.nod node program, of Karsten. It does not work on my current node editor setup.
(Red in boxes likely indicates missing node(s).)

Instead, try Max's motor2 node:
http://moi3d.com/forum/index.php?webtag=MOI&msg=7713.203
Note that this link is for an old version, and to make it work, it is necessary to replace the three math nodes with new math nodes, with the same inputs and outputs, and F formulas, to make it work.
The three old math nodes are obsolete "frame" versions...(Note the obsolete "blue" color coding of the wires.) The old color coding is even different from Max's picture, but Nodeeditor has changed
a lot over the years.
There must be a more recent version of motor2, (???), probably with a quartz clock input...
The motor2 node in the link should be updated.
motor2Q.nod has quartz clock, and also needs the motor2.3dm file.

Note that the Motor2.nod node needs the motor2.3dm file of the crankshaft to be loaded into MoI.
I ran (a more recent) motor2 node a few years ago.

The Angle node may be replaced with a Quartz node, with Hz (Hertz) input from Constant node with value 1.
