@@RY^%^&&^%$$$#.....POOP...drove truck yesterday, no leaks......drove it today and my original leak is back....WTF...leaks right at the joint seam where the pump meets the housing.
Hairline crank in head????? Leaks more fuel when engine is reved up.
been patient with the old girl but now do I hit her with a big hammer!!!!
Runs great buts drips fuel.
Pull head and increase size of O-rings....no fuel in oil so bottom seems to be sealed

Am I missing something????

Hello m186buch...get your thoughts together and describe EXACTLY what is happening? Where do you think the leak is?

It is leaking right under the edge of the head where it bolts down to the housing..
3 o-ring sets have been put on this thing now..
dropped my little inspection mirror and broke it, getting another in the morning to look in behind the head again to see if something is visible there..

didn't get to drive the truck much earlier in the year , then when I drove it I noticed a small drip..
drip got gradually larger at higher rpm
replaced O-rings...leaked the same as before..
3 sets , bought new hold downs same old leak

hello m816Buch, And when you refer to O-RINGS, are you referring to the images of packings A and B in the attachment ?

 

[m816Buch]

yup... those are 2 of the ones I replaced

 

[whatadeuce]

Do you have another hydraulic head?

 

[whatadeuce]

I believe the hydraulic head itself is leaking, where the two packings prevent the fluid in the pump body from escaping upwards past the head connection. I would replace the head. ..

I don't have another head other than the 2 that won't fit......wonder if I can replace the internals of the head?
time to call melody at AMBAC again

Thanks....Buch

What heads don't fit?

This is another potential supplier: http://www.dieselinjectionengineering.com/products.htm

This place has rebuilt PSB heads for $299: http://www.mylexinternational.com/otherservices.htm It also looks like they can rebuild your head/ pump.

I have never heard of a Hydraulic head for the PSB series injection pump not fitting any other model. According to the manuals they all fit which can make problems since some don't have the oil passages like others do. Is there something physically preventing them from mating up ? Or is the size actually different ? Also what are the numbers of these other heads you have ?

 

[m816Buch]

Sorry to confuse everyone......the 2 heads that don't fit are attached to the male human species

 

[m816Buch]

Good info on other suppliers.......I do like folks that post prices on stuff.

Here I am re assembling a code c, d, or E pump, and I noticed the part attached to the bottom of the Hydro Head spring just fell off. I guess this is what is commonly called the "button". So I asked GIMPYROB and he said the button retainer gets loose, and I should replace it with a new tight retainer, which I ordered...Anybody own a test machine?

The only injection pump tester I ever saw was at work in the "component repair section" and it was big and cost thousands !
I wish I had the money to buy one for myself !

Hi Rusty, And where is that machine now?
