D4 2t

Congratulations on your new D4, I'd be a little leery of the supposed low hours for what would have almost certainly been a WW2 era built tractor particularly if it has thrown a conrod, those hour meters can be difficult to read correctly and on older machines often quit working years ago.

When you say it wont move, is that after you cleaned all the dirt out of the tracks and bottom rollers because I suspect your track chain might be rusted solid where it has been laying in the dirt, there are fill and drain plugs on both final drives so you can easily check for water there if you make up a spanner out of a suitable sized bolt head or nut welded to a handle, same for the gearbox, almost undo the drain plug under the gearbox and see how much water drips out.

I'm usually wrong but it would be unlikely the gearbox crapped out and seized the exact same time the motor threw that rod, ask in the For Sale section for a D4400 block if you want to go down that path, I'd suggest you just buy a complete used running motor because repairing yours will cost bookoo bucks by the time you grind the crankshaft and find bearings, conrods and pistons, it threw a rod for a reason and the reason will have almost certainly been working on the other 3 conrods getting them ready to unload against the block, a good complete running motor could cost anywhere from $500-$1,500 would be my guess because guys in the USA were scrapping complete running D4's a few years back while scrap prices were $300 a ton.

In my experience, covers removed = water = brake bands and linkages rusted to the drums. Loosen the brake adjustment and get the bands away from the drums. If you are trying to get it to roll, try hooking the chain around the track midways on top as that is twice the mechanical advantage as pulling from the drawbar.

I looked at that tractor for possible final drive parts for my 2T. If I remember the serial # right, I think it is about a 1945 model. Maybe 44, because of the Green tint it seems to have. I have a 34 model 2T, that I am redoing the steering clutches in right now. D2's and attachments seemed to be the bargain of the day at that auction. Good luck on the D4, we hope to see more pictures and progress reports.

Thanks for the replies guys!
Mike I did power wash all the dirt out of the tracks and oiled them up going to get it off the trailer and see if I can get it to budge.
Stephen I will do as you suggested and loosen off the brake bands. that's my first goal is to get the thing rolling and transmission to go into gears. than start searching for a good engine.

Mike I did save it from the scrapers wish I could have saved the twenty also.

It has a very good undercarriage no wear on the pins or bushings rollers like new. I do believe the hour meter is correct it is clear as new one. I think these old army surplus machines are usually always low hours. but not to say the army operators didn't abuse them. AKA thrown Rod.

Sorry jbernd56 that last reply was for you. Yes it is a 44 model I believe. I know the guys that got the 2 d2s. I didn't see how much the running one brought. a lot of good stuff there wish I could have got more but i think this D4 will keep me busy awhile.
