ASV PT100 injector pump leak??

paul croxson · 2023-10-02 01:51

Hi all, doing a bit of road work with dozer blade, engine started to run a bit rough, parked it up, noticed a diesel leak. Seems to be from the engine side of injector. Have posted a few photos, did have a video but can’t upload hopefully someone has an idea why and how to rectify. really hoping injector isn’t stuffed thanks in advance paul

    Do u mean inj PUMP.?? All ur pics are of the pump.. Is it coming from the little hole by the name plate.?? If yes, that’s a “weep hole” telling u the front seals in the pump are getting ready to let go and fill the crankcase up with fuel..

    Hey, pump guy, yes forgot to add pump into thread. yes looks like coming from sheep holes. how long until they give way completely? big job to get pump out? Will they be special seals or generic? cheers

    They are specific.. No telling how long before they fill the oil pan with fuel.. Do u have a fuel shop close by that u use.??

    Fuel shop? Sorry lost in translation a bit in australia. service station for fuel, or someone like a diesel mechanic? we are in rural australia, was hoping to pull it off myself. thanks paul

    A fuel injection shop is a bunch of guys that rebuild injection pumps.. There is a name plate on the pump.. I need those numbers to look up the seals..

    No, not close, will be a drive away. hard to pull out? Was hoping to do that and take it somewhere if required or just do seals myself. thanks, appreciate your help

    Good pic.. I’ll look it up tomorrow and give u the seal number..

    The pump drive is NOT KEYED, therefore, when u pop the gear off the front, u lose your timing.. U have to lock the pump with the bolt on the side of the pump..& u can’t loosen it until the pump is put back on the engine a tightened back up.

    The seal # is Delphi 7174-856 you need 2.. Pay attention to how they come out..so u can put them back in the correct orientation.. Good luck

    Great, thanks very much for your help. think I will need to try and pull it out myself, as we are having a horror year on the farm. Only getting paid 50% for what it costs to produce our crop. ‘would you have the time to explain better bolt location and best directions for removal. thanks paul
