zzori Posted September 28, 2016 Share Posted September 28, 2016 So, I cant find one so I thought I'd just build one, but, I have never done this before. Can anyone start me on how to build it. I want to make a four cylinder cummings diesel for my next project truck. How do I start??? Quote Link to comment Share on other sites More sharing options...
landman Posted September 28, 2016 Share Posted September 28, 2016 You'll need either access to one and/or a photograph of all sides with dimensions.You then reduce the engine to its simplest shapes i.e. a rectangular block for the main block, a truncated cone for the bell housing, all the various components are a shape or another. the idea is to reproduce each shape in scale and put them together. I built a 702 like that.Here is the thread:http://www.modelcarsmag.com/forums/topic/101332-scratchbashing-a-702/Hope this helps. Quote Link to comment Share on other sites More sharing options...
Trailer Trash Kustomz Posted September 28, 2016 Share Posted September 28, 2016 This is the 12v 5.9 cummins I scratched as my master for casting. Block is correct size and shape but I decided to concentrate detail work on the 48re trans and the rest of the parts. It was my first shot at sctpratching up an engine. I built it with the mindset of being able to cut the block, hard, and valve covers down for 4bt applications. This is the link to a marine diesel website where I found a lot of the dimensions I needed to build mine up with. http://www.sbmar.com/ Quote Link to comment Share on other sites More sharing options...
Fat Brian Posted September 29, 2016 Share Posted September 29, 2016 Everyone is right, you can find the dimensions of just about any part online. Then just start reducing it to it's simplest shapes, just build a rectangle for the block and then start adding the ribs and bumps and whatever to it. Use kit parts when you can, all of the front and rear covers on my 4-53 are robbed from a kit 8v-71 because they look just like the real thing.

zzori Posted October 1, 2016 Author Share Posted October 1, 2016 All well and good suggestions but, where do I find drawings of a cummings tier 4 engine. I'm looking but so far no luck. Please suggest a source for drawings of that. Quote Link to comment Share on other sites More sharing options...
Fat Brian Posted October 2, 2016 Share Posted October 2, 2016 All well and good suggestions but, where do I find drawings of a cummings tier 4 engine. I'm looking but so far no luck. Please suggest a source for drawings of that. Here are two technical drawings that give some measurements of the block. Since it gives you the length you can calculate the width and height. With the basic dimensions in place you can begin to add the details. Quote Link to comment Share on other sites More sharing options...

mistermodel Posted October 6, 2016 Share Posted October 6, 2016 those things were installed in all sorts of chassis all with a bell housing swap.So a dodge,ford or chev transmission will work depending on what you ate doing with it Quote Link to comment Share on other sites More sharing options...
