ShakyCraftsman Posted August 24, 2020 Share Posted August 24, 2020 (edited) Hey all Here is my build of the 1/25 AMT D8H Caterpillar bulldozer. I'm basically building this OOB, but I'm adding a lot of details to make it look more realistic. Things like the tilt cylinder on the left side of the dozer with it's hydraulic lines. I remade the lift cylinders and added the hydraulic lines. I added a hydraulic manifold on the tube between the two lift cylinders that all the cylinders plumb to. From this I added the lines down to the hydraulic pump. I added bolt detail to both the intake and exhaust turbos. Added oil lines from the turbos to different areas on the block. I added the fuel injectors to the cylinder head and the fuel lines from the injectors to the injector pump. I will be adding more detail as I progress on the build. I found some 3D printed tracks from Shapways. I couldn't afford to get them in the fine detail resin (almost $200.00!!!) so I got them in the regular white plastic material and that process made the tracks not very movable. Let ne explain, they were printed assembled into individual side assemblies that if printed in the better material are movable. Mine are very stiff, I'm probably going to have to drill out all the pivot pins and replace them with scratch built plastic rods. All 42 per side?. Well here are some pictures for you to .ook at this view shows the dozer partially put together for pictures only. view looking from the rear forward. view from the front down. top view. view from the front of the blade. this view shows the 3D printed tracks and the modifications I made to the track slides at the bottom. I have more pictures of the engine, cylinders, and the detail I'm adding that I will post soon.

AmericanMuscleFan Posted August 25, 2020 Share Posted August 25, 2020 Superb build and very cool project Ronald! I always like when someone add details and functionalities on their build and make them better than the original kit. I don't know why but I have always loved bulldozers and you are on your way to a great build!!! Quote Link to comment Share on other sites More sharing options...

I added this bracket/mount for the fan belt. view showing the fan belt installed. this view shows the fuel lines added to the injectors. this view shows the fuel lines added to the fuel injector pump. And here it is painted. intake/exhaust side of engine. this view shows the wing nut I added to the air cleaner. And oil line from turbo to block. fuel pump side of the engine. another view of the fuel pump side of the engine. I added a line from the exhaust turbo to the oil gallery. and here it is sitting in the Dozer. I still need to give it a coat of gloss and then weather it. Thats it for now be back with more soon.

gatorincebu Posted August 27, 2020 Share Posted August 27, 2020 Ron, I really like all the detail you are adding to this dozer . You are taking this kit to another level . Where did you get those awesome looking tracks? I need like four or five sets of those . Will continue following this build thread . Be Well Gator Quote Link to comment Share on other sites More sharing options...
ShakyCraftsman Posted August 27, 2020 Author Share Posted August 27, 2020 Hey Gator I found them on Shapways, I forget the guys name right now, but if you look for 1/25 scale Cat tracks I belive they will show up. They are pricey $230.00 per set for them printed in the ultra detail resin. He won't print them in anything else now after I talked to him about how mine don't work. These are printed as a working assembly, that's why they are only available in the expensive resin, the other stuff wont work. I paid $120.00 for my set. But if you hold them out straight there stiff as a board, if you you try to bend/ move them they start to move but they break at the pins. They work really good in the proper material, it's just expensive. Maybe if you contact him you can work out a better price. It's not him but Shapways that sets the price.

ShakyCraftsman Posted September 15, 2020 Author Share Posted September 15, 2020 (edited) Hey all Here are some pictures of the Cat D8h I'm doing on Unigraphics NX11. It's only in a preliminary stage, still needs a lot of work to get it to be done. So here they are. this view shows the D8H on the 3 axle Loadking drop nose lowboy trailer being pulled by the lloonngg! Pete 359 heavy haul tractor. same view from the rear. Its only about 50% done.

ShakyCraftsman Posted September 16, 2020 Author Share Posted September 16, 2020 (edited) Hey guys Found this CAD model on the internet, it's a Cat D11...BIG!!!... It's a pretty good model, but it needed some tweaking here and there. I redid the crapy tracks that were on it. And adjusted some of the dimensions. So here are some pictures. here she is and she's a big mother! It does fit on the 4 axle trailer, just barely though. side view. view from the rear. this view shows the D11 next to the D8H, big difference! This thing actually has a model of the engine, although it's just sheet bodys not actual solids, so not sure if I could print it.
