    To the above about hp. It won’t run more than 10 seconds. I’ll try to pull the banjo above. Per a diesel mechanic, possible it needs a prime and crack each injector to clear air out.

    Hitachi EX120-2 tack adjuster leaking on zerk fitting side

    Ahh yes, if I mistyped above, I am referring to that 01 where the nut screws onto it. I put in a new fitting, and its not leaking at the zerk, its leaking about 1/4" out from it on the joint described below. It's leaking at the joint I guess where the nut 06 screws onto 01, if that makes sense...

    Hitachi EX120-2 tack adjuster leaking on zerk fitting side

    Hitachi EX120-2 tack adjuster leaking on zerk fitting side

    Hi all, have a track adjuster that starts leaking as soon as I put grease in on the zerk fitting side right under the fitting, not from the normal front end with seals. Is this a crack I can simply weld, or some sort of adjustment?
