Hyd lines on 784 Diesel

[Ensorman]

I have a broken line going across the top of the engine. Don't know the correct term or item number. I would like to ask if the four lines going across the engine are all one or are they four individual lines? The one on the end is broken. Is this a dealers item. Can't find it in any of the catalogs.
Thanks for your help.

I have answered my own question. The line is called a INJECTION LINE. Now if you can help me with the remaining questions.

The isolators/holders come off and the lines are individual part numbers. In the linked diagram they are numbers 15 -18. Cylinder 1 is closest to the fan. Unfortunately the lines are no longer offered by the dealer. When you open the link and it asks to select a dealer just X out of those options. You will have to get a used one. You will have to do a web search by the PN. Just as a random test I tried the line for cylinder 3 and didn’t get any results.

Good injection shop could make a new line for you or you can see if here are any in junkyards. Try J.P.Tractor salvage in ?Fredricktown MO then there is the parent company to this site All State Tractor Parts they have several yards around the midwest. OR Abilene machine and worthington ag parts or Colfax tractor and combine parts in Colfax IA there is a big yard in near The ID OR border near Ontario OR. so you have choices for them. IS the one that cracked bent a bit or some other issue that it cracked. I have never had one crack in all the years of diesl engines around her with most big name engines IH ,Cat,Cummins,Deere,even the Deriot V-8 car engines.

In the caseih.com parts diagram, is it Item #16 the injector return line that connects to each injector and then back to the return line to the fuel tank? This line after many years tends to leak especially in colder weather and CaseIH wants many $$$ for a replacement. Each one of the injector connections have a barbed hose fitting, so by carefully removing the old hose you can replace it by purchasing the equivalent high pressure fuel hose and clamps from your local auto parts store. The replacement hose must be the high pressure expensive fuel hose not the cheap hose.
Also make sure the return line to the bottom left of the fuel tank is not clogged.

Thanks for the information. The item number is correct. I have ordered hose on line. I hope it is the correct pressure rating.

My bad. I thought he was talking about a broken injector line from the pump . On our 574 I just removed the old line and replaced first time. Then the second time I cut the crimp off the old line so it revealed the barb on the fitting then with new hose reused the old barb that was from the crimped line. Probably clear as mud. Basically I used the old fittings with new hose on them by getting the crimped outside off. Couple dollars back then for hose and clamps.
