My intention for buying a bulldozer came up in another “thinking about” thread. However my wife wanted a bulldozer, and I decided to buy one for our anniversary for her as a surprise. Since she’s on here occasionally, I couldn’t do a normal thinking about thread. So here it is - a 1952 Caterpillar D4 dozer. We were driving it around today just having a blast. @Laurie drove it easily for half an hour or more. The kids were super excited to drive it too. Bulldozer rides were fun today. It runs well overall (after all, it’s a Cat) but has a few noted issues. - one cylinder fires differently than the others and seems to smoke. It also sounds like it has an exhaust leak, but it doesn’t - the sound comes out of the muffler. I think it might have a bad injector? Maybe the valves just need adjusted? - the fuel bowl on the gas tank for the pony motor rusted off. I think the fuel tank is salvageable but I’ll need a new fuel bowl - hydraulic hoses are beyond shot. I’m getting new ones made up - glasspack muffler is blown out and the exhaust belches pretty much in your face. I’m going to get a longer exhaust pipe and a new muffler to help quiet it down a bit My plan is to get the pony motor working properly. Right now we have to pull start it with my Ram which works fine but I do want it working correctly. We also will eventually paint it. I think I’ll adjust the valves on it but I probably need to get the pony motor working first so I have a way to spin the engine. This thing is really cool. I already pushed one stump over with it. Does anyone know a good parts source for classic Cat stuff?
