Injector rebuild?

[hughscpa]

Well the pink lady appears to be leaking from the Injector pump now. One of the leaks is where the housings meet I was told. So the question comes, is it something that can be rebuilt? Am I better off getting a rebuilt pump or a take-off from somebody? It has an LDT-465-1c in it. Any and all advice is welcome. Thanks

Sounds like you mean injection pump, not injector. I would say they be able to be rebuilt, but I have never heard of anyone doing it right. I'd buy a good take out or new one.

 

[hughscpa]

You're right, I can't spell or type worth a darn today. I may have found a rebuilt engine or two today. Have to go look tomorrow. Would I be better off swapping the whole engine or just the injection pump and saving the engine?

 

[hughscpa]

I picked up two LDT-465-1D engines today. Will the injection pump fit my 1C that is already in it or will I need to change out the whole engine?

 

[gimpyrobb]

It should work just fine. PM me if you'd like me to tell you how to swap them out.

Did it look like this? Because this is what I am finding on mine. I need to find someone to work on it locally. I am no diesel mechanic.

That looks like a fuel leak and not oil. The only places fuel can come from is the hydraulic head or the top of the viccosity compensator. (Not counting all the tube connections.) There is a pair of "O" rings that will dry out and crack in the head. That is not a bad replacement job and can easily be done on the truck. Same for the compensator cap gasket.

If I rememeber correctly Gimp has the correct "O" ring specs for the head. If you were leaking oil it would be BLACK and any fuel leak into the pump interior will still show as black.
These are not fuel flooded pumps like many others, they are oil flooded.

Just a reminder if you did not know already replace the rubber oil feed line from block to ip if you end up takeing off the ip. Sooo much easer with the ip off!!!!!!!!!!

 

[Squirt-Truck]

Great suggestion Floridianson, the block to IP line can be a reeeeal pain. Doable just a pain.

Hughscpa, If your engine runs fine Just replace the pump. Do all the basic checks before you spend the time changing the pump though.
Lex_Ordo It kind of looks like the line from the FDC is leaking? pic#5

I agree.

Also, not sure what the difference is, but on all the pumps I've worked on, the throttle lever's(in pic 1) slit is lined up with the score on the shaft it slides onto. Your's is not.

 

[hughscpa]

Will the pump from the d motor fit the c?

 

[gimpyrobb]

Hughscpa, gimme a call after noon today.

Hmm? I wish I knew more about this, but I just don't. This is the way the truck came and has been running fine since 2008.
In fact it has never run better, save for these now present drips of fuel when I'm stopped.
I have done nothing to the IP except have a friend who had performed this before, change out the hoses.
So if it's just fuel, and those two 'O' rings need to be swapped out, along with tightening the hose connections I suspect...
With no knowledge of the IP, how woud I begin to take it apart, and replace the seals?

 

[gimpyrobb]

I really think that you should check that fuel line before you tear into the HH.

 

[Lex_Ordo]

Fair enough. I will check the connections out and go from there. I hope it is that simple. This truck has been a good solid runner since it was released, and it was well cared for by the unit it was assigned to. A little banged up, but mechanically, updated and maintained.

my pump same leak getting goverment rebuild why you guys say no one can rebuild right what about gov rebuilds.and can you bypass density compensator

 

[thehaas]

mine leaks same place i figured out leaks more deisel fuel when pump switch is on .after getting pump out looks like fuel density compensator leaks internal right into govenor housing on back pump then drips out bottom.spray pump brake clean dry start truck and see where leak starts.also i think deisel pressurizes govenor housing also along with fuel.

 

[Lex_Ordo]

After cleaning everything off and drying, I started the motor. Doesn't appear to be from a hose. Definately from around the housing.

Can't even get a wrench in to play around with the hoses. PTO and other engine parts are in the way. I am taking it to a diesel mechanic to have him look at it.

I'll go from there.
