  1. Hi, been out fro a while and just getting back to work on the TD-9... I would appreciate the CAD file... The latest is that I finally got it to work on diesel on cyl 1 & 2 but the remaining two do not have pressure... I thought it might be the distribution block is jammed or plugged somehow... Just can't get the tools to tear it apart... Now I need to find somebody that can fabricate the tool... I appreciate your help and the CAD drawing... I have noticed that the primary pump pumps out a lot of bubbles... is it supposed to do that? It goes into the filter where the bubble
  2. I wonder if you ever found a home for these?
  3. The issue that I am having is that I am having only cyl's 1 and 2 (from the front) fire... did have the head rebuilt... checking the fuel bleed valves, shows that I am not getting the pressure tot he injectors, I have checked the opening valve clearance and that appear to be OK. so that would suggest that the system is holding pressure for 1&2 but then is losing pressure for 3&4... any thoughts? when I set up my Injector pump to operate on my bench, I notice that there is a lot of air bubbles coming out of the primary pump on the back of the Injector Pump assembly... that seems a
  4. Well, ended up getting a head job on it and that fixed most of the issues... in fact, it now runs on cyl 3 & 4 when I switch it over.... the currently problem is that there isn't enough fuel being pumped to cyl 1 & 2... Since the other two are working fine, I would think that the problem is in the distribution block or the lower section of the pump where the push rods are (the push rods are not pushing the valves open enough for a proper supply of fuel to get through). The second issue can be checked with a gage, the first issue I have no clue as to how to take the D Bolck apart becaus
  5. Thanks, I was about to find a hard copy online for $21.00 in Calif. Binder.com I think was their name. I will check that out, but in the mean time, I still think it is a blocked or plugged distribution block, except I can't get it apart thanks to that darn spline tool needed to remove the tips from the block ... that cannot be found. Does anybody have the spec's so that it can be computer cut out of steel?
  6. Hi everybody, been down for a while and am just getting back... TD9 1949 Rebuilt head... rebuilt primary in the fuel injection pump, didn't touch the lower section. She started up on gas fine, but when I switched over to diesel it only worked on 2 cyl's. Troubleshooting: made sure everything was properly bled, then checked the output of each diesel line to the injector (using the bleeder valve), found that injector 1 and 2 was barely putting out and cyl 3 & 4 worked like a charm. This suggests that the primary pump is working fine. Prognosis: The primary fuel pump is working
  7. Scott, I imagine that the steering clutch will be the next item that I have to work on... I can only make right hand turns... Once I get the thing working on diesel, I can at least cut some roads that I need. I have 5 acres on the side of a hill, retired, limited income... so I have to be very frugal... the TD9 was given to me when a neighbor passed... it had been sitting for about 15 years. It has been fun overall but very frustrating as well... LOL
  8. I have been searching for days trying to find some way to remove the distribution pipes from the distribution block without having the specialized tool that nobody has.... it is a exercise in futility with this search function on RPMF but hey, I am thankful that the information is here somewhere... <grin>
  9. I AM STILL STRUGGLING WITH THIS... UGH! Ok, I ended up getting the head rebuilt, after that I was able to get the crawler working on gas and it even started up on diesel... the bad part is that it only worked on 2 cyl's... Okay, here I am right now on the progress of getting this thing working. I ended up pulling the head and having it rebuilt, I had to replace several of the valves and once this was completed and the head was put back on the engine, not only was able to get it operational in gas mode, I was able to get it started switched over to diesel. So here's where the next problem
  10. Great idea, thanks... will try it Wed and see what happens
  11. That would be great news if somebody would pitch in on the subject... I think I will start a new thread specifically for troubleshooting the issues...
  12. Did you ever figure it out? I believe that because of the tooth ratio, it will take 4 full turns of the crank for the alignment marks to come back up into alignment. I tested the compression of the cylinders through the spark plug holes with the gas/diesel lever open and closed. In theory my readings should have been pressure on the diesel on... Gas off... and no pressure Diesel off/gas on setting.... this proved correct for all cyl's except #1 in which there is no change. So it appears that the valve for #1 cyl is not closing when switched to diesel which then does not provide the
  13. Would you happen to have a picture of the whole Injector pump gear as it looks when it is aligned? Thank you
  14. I did get it bled, I am of the opinion that the issue is that the timing is off. Does anybody know how to set the Gears alignment that powers the pump? There are no matching marks to align the gears together, it could be up to 2 teeth off in either direction. Now, when I put the pump back on, the hub on the pump has an alignment mark that is supposed to line up with another mark on the drive gear. That mark was about 1/2 inch rotation off, so I had to rotate it clockwise about 1/2 inch then hold it there to get the bolts on. My thoughts on this is that was my first indication that the gea
  15. UPDATE: Checked the compression of the #1 Cyl, in gas mode it was over 100 psi, swapped the injector on 1 and 3 and that didn't make any difference. starts and runs on cyl's 3 and 4... but will not fire on 1 and 2... I have run out of ideas. could this be the pump timing is off?
  16. I ended sending the aux pump with the dist. block and primary pump section out to be looked at and tested. After it came back and was installed I was able to get it started up on diesel... the next problem is that there is no power at all. I did notice that I am getting some flame shooting out of the exhaust... When I installed the injector pump, I couldn't figure out how to make sure that the gears were in alignment properly... there was not any set marks on the gears to match up. When I took it apart I tried to be not to disturb the alignment of the gears. So I set the crank (T)DC
  17. The books that I GOT WERE LISTED AS #1011492 WHICH IS THE OPERATING MANUAL, and PU-40D which is the parts breakdown of the Injector pump. I set up the test using diesel and connected a power drill to spin the pump. When the pump started to spin it drew up the fuel properly but then pushed aerated fuel with microbubbles into the primary pump section. You can see the bubbles in the line in the third picture. I pulled the scavenger valve out and cleaned it up as it was stuck, I didn't have a proper seal for it so I used an 'O' ring... do you think that might be the problem? I didn't complete
  18. found a parts book for the pump for $22.00, that and an operators manual are both on order... thanks everybody for your help... The crawler is definitely a 1949 TD9 built for Marine Corps... TDCB35043T4M http://www.binderbooks.com/crawler.htm#IH_Crawlers,_1939_Up
  19. ok, so the test didn't go so well... I was using hydraulic fluid instead of diesel and was getting a lot of air being put into the fluid before it got to the injectors. So now I am going to use diesel to see if that was the issue. Went back into the primary pump and made sure that it was put back together correctly. Since I don't have a book I am not exactly sure as to what that is... but I did take pictures and lay out the parts when I removed it and took it apart. At least the fluid is no longer leaking into the main injuctor pump as it was doing previously. So I am making progress.
  20. Thank you, what I did was to get gasket material from the auto store and made the gaskets. I am now trying to figure out how to set the timing when I put it back on the dozer. I need to find a good breakdown book or repair manual... I have set up a test bench to test the pump and verify that it is working properly then back into the dozer it goes...
  21. Does anybody have a parts breakdown of the Injector pump for the 'B' model so I can find a part number for the seals mentioned? Gary
  22. Yes, thank you.... I did find the posts you are talking about but there is no mention on how to get the scavenger valve out.... do you grab the threads with pliers and give it a hard pull? Not to keen on that because it would or might ruin the threads. Do I make some sort of tool to thread onto the top part and pull it out? Also, I have not found anything so far in my searches on what is causing the fuel to get into the pump oil. Will keep looking though. Thank you
  23. Can't say how much I appreciate the knowledge located on this board... thank you all for sharing. I have a TD-9 that has been sitting for a very long time (something like 10+ years). It was given to me by my neighbor that wanted to scrap it, but I couldn't let that happen and besides, I can use it on my 5 acres in southern Oregon. Anyway, I did get it started on gas and had fun driving it around a bit... (yes, cheap thrills for a new guy...). It would not switch over no matter what I DID. There was fuel coming out of the bleeders from the injectors but what I noticed was that although it
