Brake Differential Steering etc. - 8x8 Amphibious Vehicle Argo REBUILD Ep.8

In this video I'm continuing rebuilding the old & beat up ARGO 8x8. I'm salvaging a single UHMW chain tensioner out of eight by sanding it down to make it flat again. Still waiting for the order of a new set of eight chain slide blocks to come in after three months. Outrageous! :) Cutting the right front corner double row chain to length and installing it before anything else goes on the ARGO to make life easier for myself since there will be too little room later when the machine is fully assembled. All the air ducts get bolted in - both for differential brake steering and engine cooling. After lifting the rusty muffler up from the floor I heard a clunking noise and realized there was something loose inside the muffler. So I pulled out two burnt up baffles. I left it "as is" for the time being. I might need to cut it apart and weld in a couple of new baffles to reduce noise. But we'll see once we start this thing up. The muffler had a crack in one of the inlet pipes so it got TIG welded and both the muffler and heat shield got a nice cleanup and a fresh coat of heat resistant paint. Looks way better now. I repaired the upper handlebar/seat/support frame with existing original tubing and patched it up with reinforcement plates. Only time will tell how this fix will handle the heavyweights I'm about to haul around in this tracked amphibious vehicle once it's finished. :D All of the parts that were riveted to the tub before will now get stainless steel hardware. I bled the steering brakes and added DOT.5 brake fluid which should stand higher temperatures since brake steering produces a lot of heat. Then I removed the throttle and throttle cable, brake cable, brake lever and handlebars just to find out how rusted they were. All good in the end since everything got refurbished and installed back on the ARGO. However - my work was cut short due to power outage so some of the work I could've done did not get done. But all of that in the next episode.
