    Removing, rebuilding, reinstalling Hydraulic Head

    Thanks. Just making sure. Now I have to find the thread that talked about two sizes of o-rings for the shutoff lever shaft. Maybe I installed the wrong size.

    Removing, rebuilding, reinstalling Hydraulic Head

    Here is where I'm at. I had a leak from the fuel injector pump area, dripping to the ground about one drip every few seconds. I replaced the three o-rings. Upon reassembly, I still had a leak from the fuel injector pump area, same volume. I noticed a weeping leak at the #3 injector line HH...

    Removing, rebuilding, reinstalling Hydraulic Head

    I installed a NOS #3 injector line. The good news is that line no longer leaks at the HH. The bad news is I still have a decent diesel leak from somewhere under the side cover. Next chance I get to work on it, I will start it up and using a mirror, try to determine where the leak is coming from...

    When I removed the line today, the ferrule at the HH end was rough on the mating surface. Compared to the injector end surface, it was real rough. There was dirty diesel in the HH hole that I cleaned out with q-tips. This was one of the two holes that had the red sludge in it from the rubber...

    Thanks for the tip. I just found that site earlier today.

    I did consider the possibility that my original problem still is a cracked HH. When I had it off for the o-ring replacement I looked it over, but an untrained eye could miss the crack. A new set of injector lines is over $500, so I will try removing the #3 and inspecting the ferrule. I may have...

    Removing, rebuilding, reinstalling Hydraulic Head

    I took the rubber caps off the injector lines at the HH. While running, it is dripping about two drops every five seconds or so to the ground below the injector. Number 3 injector nut filled with diesel around the line and at the base where it meets the HH. So I'm assuming the ferrule is not...

    Removing, rebuilding, reinstalling Hydraulic Head

    There is a good thread here about a leak from the top of the HH. That could be what is happening with mine. Apparently, the diesel can creep down the sides of the HH after leaking from the base of one or more injector lines. Since I reinstalled those old lines, that is a possibility. I'll check...

    Removing, rebuilding, reinstalling Hydraulic Head

    Today I started it up and it wouldn't hold an idle, but set at 1200 it ran fine. And then I saw the diesel leak. It appears to be coming either from the top of the shutoff lever cover gasket, or the HH base just above it. A fine constant stream. I guess I need to take it all apart and start...

    I let it warm up yesterday and it didn't change anything. I'll try a more thorough warmup with higher rpms tomorrow. I have to top off the Dot 5 brake fluid, top off the axle and trans oils, and check the air in the tires before I try moving it. It has been sitting for about two years now.

    Thanks for the advice. If I screwed up and moved the HH red tooth one slot either way would that result in the engine running the way it is? How do I know if an injector is malfunctioning? Is there a way to diagnose each injector?

    Mine is also surging when I set the hand throttle at about 1100. It runs a while fine, then surges, then tries to die if I don't work the hand or foot throttle. Big puffs of smoke when I accelerate the throttle. I can back off the screws a tad and see what happens.

    Removing, rebuilding, reinstalling Hydraulic Head

    I'm back to working on my 1970 M35A2C LDT multifuel. I had the leaking HH problem, so I removed the HH and replaced the three o-rings. When I took the injector lines off the HH, I discovered two of them had some orangy gunk down in the HH hole after removing the lines. I cleaned the gunk out and...
