Did you pour fluid into the pump "hose" before you installed the reservoir or did you just install the hoses and reservoir and fill it up with fluid inside the reservoir? It helps to fill the pump body up through the big hose before putting the reservoir on. Also what fittings are you referring to when you say inlet metal? Do you mean the main line that goes to the transfer case. If it is leaking there then yeah that's a serious issue that would most definitely stop the pump from building pressure. It's leaking all the pressure out of that fitting if so.

 

Actually I'm not sure what fitting you mean but really it doesn't matter what fitting because it cannot be leaking any fluid, even a little bit, from anywhere. These things run at like 10-15 bar so any leak at all will stop pressure build up. Although I am still interested in which fitting you are talking about though.

 

It's the fitting that the inlet hose slides onto at the top of the pump. By top I mean the end with the inlet/return hoses when the pump is in the vertical orientation in evo 8/9.

At the base of the fitting there's a small epoxy ring that seals that joint to the pump body. I bought a tube of this oil/gas resistant gasket sealer - hopefully that does the trick. It's the low pressure side.

 

Can you post a picture please?

 

Will do. I have the pump apart now. I think I messed up the orientation of the pump plate.

The wider side of the groove should be facing towards the center of the pump right? I missed that when kiki said the plate should be facing down. I wasn't paying to how he had his pump on the table.

In the picture that is proper orientation of the pump plate right?

I had it the other way around.

 

Yeah that is right how it is there. What's the blue stuff? Sealant??

 

Thanks for posting a link to my for sale thread.

I hope the OP can figure out his problem. I dont think he needs my pump. I am willing to work a deal on this ACD pump I have for sale though. Time to let it go.

 

Thanks for the help. I appreciate it.

Back out in the garage. Late start. I should be good to go at this point...hopefully

 

Can I ask what am I doing wrong when after I tighten down the bolts inside the pump head an when I go to test to see if the gear still spins using a screwdriver to rotate the coupling why does it no longer turn? Is that normal. It doesn't seem right.

 

Yeah that blue stuff was sealant. Not sure if that's a good idea but I was planning on giving it a shot

 

This is the busted seal I was talking about. at the base of the inlet hose.

Just going to re-epoxy it. should be good to go.

 

I am happy to report the pump is working!!! Hooray!

*****NOTE*****

I ordered my pump rebuild kit off of ebay from a vendor in Canada. I don't want to blast the person because it could have been an honest mistake.

BUT

The pump plate was too thick. The rebuild kit plate measured at 2.75mm and the stock plate measured at 2.50mm. This extra .25mm wasn't allowing the pump head to seal properly with the pump body.

Everybody who is reading this about to dive into this job - make sure you plate is the correct thickness otherwise the pump will not go together properly.

Glad it wasn't my total lack of mechanical aptitude for taking this long. ....this time.

 

I actually bought a kit from the same place the first time I ever rebuilt one of these and I had the exact same issue. My buddy does cad/cam design (or whatever it is called) and he cuts my replacement plates for me out of titanium alloy and a water jet. The ones I use are amazingly close to stock and always work perfectly. The alloy has a little copper built into it as well so that the plate will never corrode again. I have really kicked around making a business out of these plates and rebuild kits but just never got off my lazy butt to actually do it. Maybe with the acd guys out east going out of business now this is a perfect time to finally do this business. I also have a bench harness made up for flashing the acd ecu and an openport 2.0 to finish the job. I'm rambling though, congrats on getting it fixed man. And its funny (sort of) because if I knew you had used that Canadian company I could have told you weeks ago what you issue was lol. I emailed them awhile ago and offered to share my cad design so they could put out a decent product and they never responded, so screw 'em I guess.

 

Oh man.....that information would have been soooooo helpful on about Monday night! haha. I can laugh about it now because it's fixed.

Yeah I'm disappointed I paid 200 bucks for that kit and used ZERO of it.

 

Yeah even the orings I got in that kit sucked. I had to go back to oem orings. Thats why I mentioned orings before. I guess what upsets me is the fact I offered them my personal cad design that works flawlessly for free and they ignored me. I guess they are okay with ripping people off......and I just measured a stock plate with a digital micrometer at 2.50mm and mine is 2.55mm so yeah. I've got the goods lol. I just buy the titanium sheets and have them cut out of that. It's super cool watching the water jet machine work that he uses to cut them for me.
