  1. If it was me and I did not plan on using the dozer much I would just swap the better head onto the 335 motor. I do not believe that there was a huge performance difference between the two engines. The TD-9 engine and sleeves are also getting very expensive. Last time I checked they were selling for $500.00 per hole. Another option would be to get your 4-3/8 inch sleeves bored out to 4-1/2 inches and clean up your old pistons. Rings for either engine are still readily available through Hastings, but not cheap.
  2. Crankshafts should be the same they just changed bores over time 335, 350 and 370 cubic inches, 4-3/8, 4-1/2 and 4-5/8 inch bores respectively. You will have to make sure you get the correct head gasket for whichever engine you are using. if I remember correctly some of the early engines had the sleeves flush with the deck and the later engines they protruded several thousands. So on the early engines the gasket set on top of the sleeve and the later engines they went around the sleeve flange. Good luck.
  3. Trucker is correct. These holes are also used when mounting a winch. See photo below. Gene
  4. I would replace the fuel filters first before digging into the injectors or pump.
  5. There should be no difference between the two injection pumps or engines that I know of.
  6. yes, a little confusing when you first look at it
  7. Vic, That is what the drawing shows studs #1, 2, 3, 16 and 19 (5X) in the middle. Studs #5,6, 8, 10, 12, 14, 17, and 21 (8X) next to the injectors. Studs #4, 7, 9, 11, 13, 15, 18, and 20 (8X) next to the intake and exhaust ports for a total of 21 stud bolts. should work for your application.
  8. Yes, just purchased it about 2 months ago. Problem is it has been jury rigged for so many years I am having to go through everything, electrical is the worst. Hope to have everything fixed in another month then paint. Also replacing lots of hydraulic hoses.
  9. Fatboy, 9 times out of 10 it's the tilt cylinders leaking internally. I just rebuilt the tilt cylinders on my Clark it40B with the same issue.
  10. Vic, Attached is the tightening sequence from my service manual. Slightly different from yours. Let me know if you need anything else Gene
  11. Where is the engine located?
  12. Check the shaft seal and gasket on the transfer pump as either one will allow fuel to enter the pump housing. Redwood
  13. Old Iron, Check out the attached link https://www.ebay.com/itm/Caterpillar-Crawler-Dozer-International-headlight-Brush-Guard-new-in-box-Tractor/254847107203?hash=item3b56124083:g:bHQAAOSwNM9gEZzu
  14. Just sent you a PM with all the gory details
  15. Might have some bits and pieces left over. I will PM you with details. Gene
  16. Saw this on E-bay and thought someone may be interested https://www.ebay.com/itm/IH-International-UD-18-UD18-TD-18-TD18-Engine-Head-Gasket-Set-Assortment-259893/154172774052?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 Gene
  17. Fill the fuel tank to the point that you can gravity fill the primary filter then fire up on gas bleed the secondary filter, crack the throttle and bleed the injectors. good to go. You might want to change the fuel filters at this time as who knows what you might have sucked up from the tank. Gene
  18. When you call Associated Tractor ask for Tom - Owner
  19. I have also used Manila file folder paper for the thin gaskets with success. Gene
  20. Attached is something that I downloaded from Red Power a number of years ago. I believe from MB Cat. Hope this helps. Gene
  21. If you are getting fuel coming out of the fuel pump top cover it is most likely the gasket that goes between the auxiliary pump and injection pump. this gasket has to seal the return flow of fuel coming from the injection pump. Be careful when putting in a new gasket as there is nothing to hold it in place so one side must be glued. The shaft seal could be the culprit but it would have to be severely damaged. Gene
  22. Sending unit should be located at the back of the head
  23. PA, Keep in mind that the UD-16 is the 6 cylinder version of the UD/TD-9 engine so they share a lot of common parts. Gene
  24. Appears to be a UD18 stationary engine. Could you please post a photo of the back side of the engine? Gene
  25. Oldiron, It was relatively easy for me to make the swap as I had the complete parts crawler to rob all the necessary parts. Let me know if you need anything else. Gene
