“In this assembly session, you will install the alternator with its pulley and belt, the crankshaft pulley, and the supercharger and water pump belts.”




Materials: The Alternator Piece 1 and Alternator Piece 2 are metal – all other parts are plastic.

Assembly Guide (Digital Version)


Assembling the Engine Block Part V

The Alternator
Stage 17.1

Fit the post and smaller pin of Alternator Piece 1 into the matching holes of Alternator Bracket 1, as shown. Secure with one (1) AP screw:

Stage 17.2

Retrieve the Engine Block assembly from the previous stage. Slide Alternator Piece 2 over the post of Alternator Piece 1 and place the Alternator Bracket 1 to the front of the Engine Block assembly, as shown:

Secure the bracket to the engine with one (1) CM screw (circled in red below).

Take note of this small pin as well (circled in yellow below). This will be used in the next step. This is also your friendly reminder to try using 3-in-One Oil on all screws going into metal:

Stage 17.3

Position Alternator Bracket 2 over the post of Alternator Piece 1, as shown. Ensure the long post of the Alternator Bracket 2 fits over the pin of the Alternator Bracket 1 (the one circled in yellow in the previous step and below). Then, secure this bracket to the water pump part of the Engine Block assembly with two (2) AP screws.

If this bracket does not line up with the two holes in the water pump, try adjusting the Alternator Bracket 1 from the previous step:

Stage 17.4

Slide the Alternator Pulley (Piece 2) over the post of the Alternator Piece 1, as shown:

Next, slide the Alternator Pulley (Piece 1) over the post of the Alternator Piece 1 as shown, and secure both parts with one (1) AP screw:

The Crankshaft Pulleys/Belts
Stage 17.5

We built this pulley on the work surface, then put it on the engine. These are all the parts in order. The Crankshaft Cap (nearest the engine) is on the left:

Next, stack the two Crankshaft Pulley (Piece 2) on top of the Crankshaft Cap, like this:

Finally, stack the Crankshaft Pulley (Piece 1) on top:

Slide this entire assembly over the large bottom post of the Timing Cover, as shown, and secure all of these in place with one (1) CM screw:

From the side, this is how the mounted pulleys should look:

Stage 17.6

Fit the larger Alternator Belt around these three pulleys, using the second groove of the fan/crankshaft pulleys as shown:

MOM: We used tweezers to ensure the belt didn’t twist while placing it on the grooves of the pulleys.

Stage 17.7

Fit the smaller Water Pump Belt around these two pulleys, as shown:

Stage 17.8

Fit the toothed Supercharger Belt around these two pulleys, as shown:

The Cooling Fan
Stage 17.9

Press the pins of the four Cooling Fan Blades into the matching holes of the Cooling Fan Base, as shown:

Stage 17.10

Secure the Cooling Fan assembly to the Fan Sprocket as shown, with one (1) AP screw:

Stage 17.11

Slide one end of the Alternator Wire over the pin on the back of Alternator Piece 1:


MOM: Another fairly painless stage done and the engine is beautiful so far! I especially love the color of the spark plug wires – could be because I am partial to blue.

  1. I noticed the blower drive is not correct. On a real roots type supercharger like this one and on most other supercharger types as well the supercharger is driven off of the crankshaft pulley and it would have a belt tensioner as well. Even in the movie where he’s showing the engine in the car with the hood up, it’s setup that way, not driven from the water pump pulley as this model has it and without a tensioner. This is not a realistic way to drive the blower and would never work in a real life situation. So this models setup is odd.

  2. I have a problem with the some part. You see, at Stage 17.8 where it says to connect two pulleys as shown, the 2nd pulley (upper one, white) that is attached to a block onto 1l, it just doesn’t fit well…What did i do wrong?

    1. Do you mean the supercharger pulley is loose? If so, it is possible that the screw became stripped. You can glue the pulley in place if needed, it does not need to turn.
