pulling the hpop AGAIN

[Hawker]

for the second time in 3 days, I'm pulling my HPOP to change out the o-rings. the small plug on the IPR side leaked first, so i changed that and also changed the output line o-rings, all with regular o-rings (yes yes, i know...)

well 40 miles from home tonight, the truck started puking oil. had to stop halfway home and add 8 quarts. I'm looking on the bright side and at least i got an oil flush!!

anyways, anyone have any hints or tips or tricks while i have the entire thing apart again?

If you're not using the Loctite 608 retaining compound, you will never get any o-rings to hold up. There is a specific procedure that must be used to have the fittings hold for the long term.

I replaced all my o-rings over a year ago with THIS procedure, including the small plug on the bottom and still have no seepage anywhere.

my father just picked up the kit from ford to do it, has the loctite and the 3 orings, but it was that "non servicable" plug that was originally giving me problems. ford said they don't have an o-ring for that one...

how convienient when dieselorings.com has the entire thing...

Yep, if that thing is leaking, Ford says it's trash and try to sell you an $800 pump..... That's what got me PO'd!

If I remove the "Do not remove" plug and replace the O-ring, why will it not start now??

[Hawker]

i was told theres a plastic or metal ball bearing in there that you can't lose. mine didn't have one, just had a rod on the end of th eplug about an inch long.

do you remember that coming out?

TRY BLEEDING AIR OUT OF HEADS. REMOVE ICP SENSOR TAP IN HOSE INTO CONTAINER AND SEE IF OIL COMES OUT. IF STILL DOESN'T START PUT ICP BACK IN AND PROBE DARK BLUE & LIGHT GREEN STRIPE WIRE AT SENSOR WITH VOLTMETER SET AT LOW DC VOLTS

WHILE CRANKING IF YOU DON'T HAVE A MINIMUM OF O.83 VOLTS IT WILL NEVER START. ASSUMING YOUR ICP IS READING CORRECTLY. 0.83 VOLTS IS EQUAL TO APROX. 500 PSI HPOP PRESSURE THAT IS THE MINIMUM REQUIRED TO OPEN INJECTORS (IF POSSIBLE YOU CAN DOUBLE CHECK WITH A GAUGE PORTED TO ICP LOCATION)

IF READINGS ARE BELOW MENTIONED SPECS YOU HAVE HYDRAULIC HPOP ISSUE PROVIDED THERE ARE NO MAJOR LEAKS ANYWHERE (INJECTOR SEAL OIL RAIL SEAL ETC)
