On my D4D #78A5667 tractor we tried pulling all the glow plugs to see what condition they were in. Two came out ok & two did not (one of the ones that came out had a crack on the electrode end). One of the stubborn ones came out part way & then the tread started binding, so we ran it back in. Put tester on & they all draw around 4.5 amps on 24volts.
I see that the one appears to have a number on it, which looks to be "A73" (not sure of the number). I would like to check into getting a new set seeing that one had a crack in it. Anyone know if that may be a good number & who makes it if in fact it is available through aftermarket? It is the original motor in the unit as the same ser# in on the engine block.
Also, we need to pull the injectors to get at the stubborn glow plugs. Does anyone know how to identify the special socket or tool that turns out the injector body? My parts book does not show that style of injector body. See the attached photos.
