HELP homemade hpop setup problem

[B.A.D Performance]

Im guessing since it builds 20-25 psi in the resivoir while crank ing I need a check valve that opens at a pressure lower then that

 

[Magnum PD]

Some open at 5 psi.

 

[B.A.D Performance]

Wouldn't you need one with low pressure like 5psi? That way it will open to feed the haldex? You may be onto something

 

[Magnum PD]

Yes it needs to be low pressure, pointing the right way, and made for oil.

 

[B.A.D Performance]

Its for oil and its in the right direction. Ill have to double check the valve open pressure

Quick update. I bench tested the haldex pump by hooking a hose to the inlet and outlet ports and a bucket of hydro oil. Spun the pump over counter clockwise and it pumped the oil out no problem. So I know the pump plates are reversed correctly. Check the part number on my check valve and crack pressure is 5psi.

Where do I go from here? Ive double checked everything. It all checks good. What am I missing here?

You need to know the actual pressure the pump is outputting

 

[B.A.D Performance]

What I dont understand is wouldn't the truck start even if the haldex is shot? Thats the whole point of the check valve so the stock hpop doesn't back feed

 

[ghohouston]

Got me stumped to be honest. I've never messed with a gen 3 style setup. I am following closely though, very interested to know what you find.

 

[Magnum PD]

Did you the line off that goes to into the hpop? See how much oil is coming out of the Haldex?

 

[B.A.D Performance]

No thats my next step. Turn it over on the motor and put a guage on it. I just want to know for sure the rotation was correct

once this is figured out you should do a diy thread on how its done..

Well it appears the haldex took a crap. Tore the pump apart. The internal rubber and teflon seals completely disintegrated. Not sure what would cause this

dead heading it with no IPR most likely

 

[B.A.D Performance]

Thats what I was thinking. I doubt you can just buy new seals for this pump. So looks like ill be buying a new haldex

 

[lincolnlocker]

how much does a haledex pump cost?

live life full throttle

 

[B.A.D Performance]

200 or so

 

[m j]

i wouldn't doubt a kit is available

So I have one of these HPO reservoirs now... How does one go about getting the gear to mesh with the existing HPOP gear?

I've never been a big oil guy... but for this price??? Hummmmmmmmmmmmm
