450 Case Crawler

I've gone off the deep end and am buying a 450 Case Crawler. It hasn't run in a couple of years and has a rebuilt engine with less than a hundred hours on it. I drained almost a gallon of water out of the tank and no diesel so I'll be pulling the bottom inspection cover that will allow me to reach into the tank to see if there is any crud in the tank. Supposedly the tracks would slip off if it turned sharply, but that appears as if the tensioners are stuck and the chains and tracks are acceptable. The starter was giving problems so I'll be pulling it tomorrow to check it out for lube and brush life left. Will also check the hydraulic oil and once it is running I'll be changing all of the lubricants and filters. I found the serial number tag was sandblasted leaving the imagination to what model it really was. The engine has a casting number that states 1972 and that is all that I can find. Does anyone know where there are pictures to determine which year the Crawler is? The price is great and it has a torque converter so it's not a manual transmission like some older dozers are and it has a six-way blade unlike the 450 Case dozers that have the ball-pivot that so many won't loctite the bolts in place and they have to be tightened every day. The excuse they use they use is that the factory recommend not doing that, so the old rentals I've been using have to be tightened daily and that makes no sense. Lousy mechanics don't seem to have much experience. I'd appreciate any and all information concerning this 450 Case Crawler, so I can at least identify it when buying parts.

If it has been setting for a couple years with water in the system and you turned the engine over I'm betting you are going to be looking for a replacement injection pump.

Go on he net and type in case dozer 1972

I dropped the lower diesel tank inspection port and found rust powder. There was no diesel to speak of present. When I remove the filters I will be careful to see if any water is present in them as there appears to be two of them stacked before the injection pump. I don't believe the dozer has been cranked in the two years that it sat, but am not ever positive about anything unless it's under my care and then ?? I saw a casting number near the lower part of the diesel engine and will know more after I disassemble the starter and inspect it as they were having some trouble with cranking, but I think it was because the battery was sulphated and the GM alternator is probably toast also. Lots of probables, but until I get into it further I won't know anything. From what I have discovered online the dozer is a 450C diesel versus a B that's gas, Correct? If my memory serves me the casting mark stated 2 - 1972 in a big cartouche and it's near the pan or lower engine. There are more numbers preceded by an A cast to the left of the broad casting number on the left looking forward or the right looking backwards.I won't be cranking it till the starter is inspected and serviced by me and the prefilters are changed and the tank cleaned out and it is bone dry now. I have a sneaky feeling the pump will leak and needs a rebuild along with probably every hose on the machine. Just saying.At least there is no evidence of diesel in the oil, but until I remove the drain plug I won't know about water in the engine oil. The engine has less than a hundred hours on the new hour meter replaced when they installed the rebuilt engine. The chains are okay, the shoes abour half life and I am a welder so they are no problem to add new points to them. One tensioner is stuck and the other probably needs attention. It's possible that rain got into the exhaust pipe as it has no rain cap and is bent to keep the angle out of rainfall but the pipe is bent slightly and it's possible that some rain could have gotten in, but until I try to crank it I won't know if it is locked. That's never good news.I do appreciate every tidbit of information that you can spare and I have a lot of experience to boot. Being retired on SSR is great as it gives me the time to do what is needed and I'm only slowing down to about half speed.
