Just saved from scrap yard HD4 dozer

Look for POST REPLY on the left side above and to the left of quick reply box... when you make the next post...

 Being you created this thread, you would have had the full reply editor... and in the top of the icons, and the seventh icon from the left you will find a tree in a box or frame... click on that icon... that will bring you to 'image property' page.
  If the pictures are on your computor, I resize pics to 998 pixels in width for ease of downloading......
Now look for 'BROWSE' and click on that,
 then find the picture you want to put up and click on it and hit open.
 then click on 'UPLOAD'
and a dialog box will appear and says 'Please be patiant while the image is being uploaded to server' and click on 'OK'
 Wait a moment and image appears in box and then click OK again and image will appear where your marker is in thread.  I almost always have the marker on the start of a new line. .....

   Now if you have your image on the net somewhere, go there and copy the url location of picture, come back here and click on full reply editor,
 go to the tree in the frame and click on the tree
in the right column, you will find IMAGE URL now paste the address of image location and then make sure there is only ONE Http:// , not two - http://http:// hit okay and picture will go into message where your pointer is.

Hope to see some pictures...
.

nice find.  that will be a fun little guy when you get it going.

Oh Oh, looks like somebody stole the radiator!  LOL (yeah, I know it's on the back side of the engine)
Tracks look like new, great find, hope getting it going isn't too big a deal.

thank you so much for the information on where to find my serial number it was right where you said it was mine is 1850 so it's an early machine..
   I got a cranking over in the motor sounds great but the injection pump is absolutely not putting out any fuel I took the top cover off it looks very Rusty in there I'm trying to soak it in some PB Blaster looks like the pump was new at one time don't think this machine ran in a long time I don't have any information on it pump could be even installed wrong but it's not pumping fuel

CC it looks like someone added the grouser bars seeing how square they are cut. You need to cut or round the corners taking off around 3/4 of an inch or whatever looks good to you. This will help the machine turn much easier, not tear up the ground as bad, and also not get stuck as easy. Looks good.

Yeah, I now see somebody welded onto the grousers, should have looked closer!

The injector pump is probably why it made its way to scrap. Will need bring the engine up on time, drag the pump off and have it gone thru. Most likely sheared the internal coupler.

The serial number was on the torque converter trans housing on left side top side on flat surface, and yes that's a MF200B dozer

Did you bleed everything?   Taken the lines loose at the injectors to see if fuel is even trying to flow?

Yes, good fuel flow with full tank of fuel, and fuel is just not filling the pump..it should fill it and even run out top return line right?

Ok thanks, I pulled it apart, with instructions I found on the net, and the only thing I may see wrong is these rollers won't rotate dues to rust

Those blocks the rollers are in, they need to be free too... as well as the plungers below the blocks.
You probably already seen this vid... Look at about 7:12 mark

JC, thanks again for the tips, I saw the first video, but not the second, you were correct plungers ,rollers and blocks stuck
..THE JOB IS DONE AND SUCESSFULL!..it was still hard getting to to fire for the first time, but running better and better!

Nice save on the HD4! Where are you in PA? What did you have to do on the steering clutches?
Regards,
