2x tall 10 pieces with holes,

2x tall 12 pieces with hole,

2x tall 2 pieces with crossbar hole,

3x tall 4 pieces with holes,

3x tall 2 pieces with hole,

8x tall 6 pieces with holes,

12x tall 2 pieces (regular)

1x driveshaft u joint,

1x propeller/fan (optional)

4x T crossbar pieces,

6x long crossbar wheel stopper,

2x short crossbar wheel stopper,

2x long crossbar,

4x kinda short cross bar,

2x shorter crossbar,

3x shortest crossbar,

4x 2 level crossbar stopper,

2x low friction pin,

4x low friction pin cutoff

1x medium gear,

1x medium gear w/ bent teeth,

2x wheel with holes and no tire,

2x front wheel,

2x rear wheel,

2x tall 1 space wide slanted piece (needed in making track for other piston (continued))

Make Crankshaft

DSC_0324.JPG

use 2 level crossbar stoppers and shortest crossbar and T crossbar pieces to make the crank. on the rod use shorter crossbars to connect the 2 T pieces and I think you can see the rest.

Make Crankcase.

DSC_0325.JPG

use tall 6 pieces to set the crank in. for base use the flat 6x16 piece. leave 2 places in front for "radiator" thing

Put in Cooling Fan

DSC_0326.JPG

put cooling fan on front of "engine"

Making Fan Cover

DSC_0327.JPG
DSC_0328.JPG

build up 3 tall 2 pieces on each side of the cooling fan and put the flat 2x6 on top

Making Track for "piston"

DSC_0329.JPG

stack 1 of the tall 2 pieces with the hole in it on each side of the "piston" (make sure you put these on the back of your engine)

Making Track for Other Piston

DSC_0330.JPG

on top of the "radiator" box put 2 tall 2 pieces 2 spaces apart

Making Track for Other Piston (continued

DSC_0331.JPG
DSC_0333.JPG
DSC_0338.JPG

put the slanted pieces on the tall 12 pieces and then put then slanted piece toward the front onto the top. put two tall 2 pieces on to of that one space from the end so when you turn the crossbar from the crank the "pistons" will smoothly go up and down along their track.

Putting on U Joint Driveshaft

DSC_0336.JPG

that seems pretty self explanatory put it on the opposite end that the fan is

Put Wheel Base On

DSC_0337.JPG

use the tall 8 piece to put the other flat base on the back

Adding to Rear Wheel Base

DSC_0343.JPG
DSC_0346.JPG

add 1 tall 6 piece with holes on either side of base and then a tall 4 piece with hole on the end.

Making Rear Whells Work for Me (depends on Wheels)

DSC_0347.JPG
DSC_0348.JPG
DSC_0350.JPG

put 3 cut off low friction pins on opposite sides of wheels with hole and insert the onto the other wheels. I did this because my crossbar for rear wheels was not long enough.

Drive Shaft Support and Putting It In

DSC_0352.JPG
DSC_0353.JPG

the first picture looks pretty self explanatory. put the drive shaft through the 2 hole piece and the push the piece in one line away from end

Making "differental"

DSC_0355.JPG

put the gear with bent teeth on the end of the drive shaft. ( you will adjust it later)

Put Rear Axle in One Rear Wheel

DSC_0357.JPG

again that is pretty self explanatory

Finish Driveshaft

DSC_0359.JPG

put shaft you just made through the back piece and put the other gear on that and the other wheel on the other side and adjust gears as needed

Your Done

I added a body and stuff just to look cool but do what you like
