I'm looking to buy a John Deere 450c dozer. My questions are mainly about tracks but I'll listen to any input. The owner claimed the dozer was sitting on a pile of poop for many years and the tracks are rusted to that shape. Looking at the tracks they are stiff. He claims that you can do allot of damage if not fixed. Is that something I can do? If I have to take them in he said it will cost about a grand to have the pins pushed out and fixed. Can I just try and soak them in diesel to loosen them up? What do you suppose something like this is worth. It looks to be in good shape. Owner claimed it's got new drive sprockets.

One could probably free them with soaking and repeated flexing them with movement - or if they are worn some by having them pressed out and turned if other side is good .

track work ins't cheap but sometimes it's the only option if

I have heard that diesel fuel and a BFH works. lol. I know of someone that discarded their tracks from a 450 JD loader because the pins and bushing were seized and bought all new rails and pads without even trying loosen the existing tracks. He simply torched through a link and scraped them. I saw them and compared to his new rails and the old rails, pins and bushings looked 100% with no signs of wear at all. I expect that they are still there so if someone in the Pacific NW or in western Canada needs next new tracks they can probably be had for scrape metal price. The pads were a little beat up as if they had been used in a rock quarry. Two new links would be required to replace the two that were cut with a torch.

Hate to say it but what made them seize in the first place is best source to break them loose, Moisture or Water. We had old crawlers a road builder left sit over winter as they vacationed, all dry pin rails, they would hose them down with a garden hose a few days then keep them wet and operate them for a day or two, pins would ooze rust and free right up. Be mindful of the screeching as they will be dry pins and any material inside the busing with the pins will cause noise.

Thank you guys. It brought a bit more then I was willing to spend. It brought $9750. To me that was a bit much for something that had sat that long. Plus after looking it over a bit more the oil felt very gritty. Hydraulic oil was a nice cream color. To much made me nervous. I'll keep looking though for something of that size

I had both 450B and C one time I bought a set of rails with pads that looked to be in good shape except some links that wouldn't striaghten out, thot I'd run em a while and they would be ok. Well found out they were on a machine used for loading salt sand for icey roads. Instead of getting better they got worse, and was told by JD dealer the only way to fix then was to push the pins out and clean them and the bushings and re-assemble. I chalked it up to learning experience and thru them in the scrape pile. 450's were good machines in their day but by now are way out dated. Rubber track skid loader will do more work than 450 and you can take it into the back yard with no damage.
