Does anyone have experience with leaky pump or connections to pump? I have a slow one and it's driving me crazy trying to see where the fluid is coming out. It is definitely from the pump area (not cylanders) because that's where the puddle is...but everything seems dry and tight on the pump and hose connections. Fill plug nice and tight, also.
Put baby powder around the connections and fill port plug. That will show where the leak is coming from.
That's a great idea, Russ - I will try that tonight, thanks!!
the hydro-e-lectric pump is divided in two parts, one is electric to drive the pump, and the other is the driven pump with reservoir. There is a large o-ring that seals the two halves in the middle; if your plug and lines are dry, then that is the next suspect.
Also, the pump was filled with brake fluid, which absorbs water, so you could have a rusted reservoir with pinholes at the bottom.
Get a new set of rubber mounts if yours are old, unplug and remove the pump assembly, hold it up in the air, and you'll see the source of the leak if it's not the lines. Don't try to reuse the rubber mounts if they're original. life is too short to deal with hard rubber, and the pump will be much quieter if you replace hardened ones.
Great information and very helpful! Thanks so much, Mark!
Turns out the leak is the opening where the three electrical wires (up, down and ground) come out of the motor. Even if you tip the motor when it's not running, oil leaks out - and pours out pretty fast when the pump is operating. The O ring sealing the two halves is fine. There must be another seal somewhere inside the unit that is bad, but I don't know if this is accessible or if replacements are available. Ugh.
Sounds like a new pump assembly is in order.
there is a lip seal that goes around the shaft of the motor. If is coming out of the motor end, it must be coming through there. It would be a pain in the butt to find such a one-off seal, you don't know if the shaft is pitted, and even if you can fix the leak, now your electrical end windings are covered with brake fluid or trans fluid, so it's a matter of time before it gives out.
I'd replace it.
Yep - I took the pump out and totally disassembled it. The leak isn't coming from any of the serviceable parts...it's coming from the electrical motor part that is permanently sealed in metal. As you point out, with oil all over the motor it's just a matter of time.
The shocker is how filthy the oil is. Very dirty and soiled. A new pump is a must, but I'd hate to get a new one then run so much crud into it. On the other hand, the last thing I feel like doing is spending over $500 for new everything and then having to take out the seat & side panels to get at cylinders. UGH.
Just my best guess — but if you can plug the leak at the pump wires with an epoxy —that is always oil and fuel ( gas ) proof
J B Weld — comes to mind
Clean any surface completely around the wiring with alcohol ( and Q tips ) to remove any pump oil residue in the area to secure the bond and fill the wiring area with the epoxy and let it dry for the recommended time
I have only used the slow dry 6 hour type myself not the quick dry
If you can seal the leak that way the pump may come back to being useable
Do not have much to loose so worth a try
If you can stop the leaking that way the JB weld will be a forever fix
That might ( could ) work for you so worth a try as I see it
My suggested fix is a bit of a long shot as suggested — so replacing the unit should be the best way to fix this so you can forget it and move on to the next Repair required the car may be needing
