This is my build of a Caterpillar 657G scraper.
This is one of my first mods that I made directly from a model, so it has some issues and doesn't look perfect, but it works pretty well and has the features to be considered like a Caterpillar 657G scraper. a real scraper to work with.
Interior space isn't great as the model I had didn't have much interior space.
This is the 637K model so it's not a perfect 657G but I enlarged the machine to the right size and also increased the weight to make everything fit the larger 657G exactly. You will also need to download my Caterpillar 304E2 as it creates the shop categories for this equipment and accessories.
