This is one of the most complex models you'll see. It will test your printers reliability and endurance so make sure you have a well tune machine before printing. Every part was designed in SolidWorks with 3D printing in mind. All printing was done on a homemade RepRap original Prusa and homemade Kossel mini.
The engine features working pistons, crankshaft, valves, cam, rockers, etc. If you have never assembled or seen inside an engine then assembling this with give you a good idea.
The transmission and transfer case are fully functioning too. Shift through the gears and see the rotational output speed change. Learn how a transmission works!!!
You can see the engine, transmission, and transfercase working by clicking the links below.

Please see the assembly instructions which you can download from the links below The parts list files have special notes for printing as well as a hardware list. The engine and transmission have an assembly drawing and the transfer case has a pdf file with instructions. The engine block and head have two different STL files. One with support and one without. The engine block needs support for the mains but some slicers will put support other places where its not needed so I created a STL with built in support. http://www.filedropper.com/assembling4wdtransfercase http://www.filedropper.com/blockassem-sheet1 http://www.filedropper.com/camassembly-sheet1 http://www.filedropper.com/crankshaftassem-sheet1_2 http://www.filedropper.com/headassemforcambolts-shee http://www.filedropper.com/headbracewithrockerarms-s http://www.filedropper.com/pistonassembly-sheet1 http://www.filedropper.com/sectiononebreakdown-billofmaterials-sheet1 http://www.filedropper.com/sectiontwobreakdown-sheet1 http://www.filedropper.com/shiftlinkage-sheet1 http://www.filedropper.com/timingcoverassem-sheet1 http://www.filedropper.com/valveassem-sheet1 http://www.filedropper.com/partslist http://www.filedropper.com/partslist2 http://www.filedropper.com/transfercasepartslist
