Military CAT D7G Dozer Was a Steal...Until It Wasn’t

-We’re back in the shop working on this military CAT D7G dozer — one of the cleanest, lowest-hour tractors we’ve ever had. Until we found a few surprises. It’s time to go through the entire machine: service, filters, leaks, and a full check-over before Kevin and the crew get it ready for paint. But of course… nothing ever goes exactly as planned. Follow along as we drain fluids, rebuild cylinders, and discover a few surprises hiding inside this old war machine’s winch.
