Hydro Leak in Pump

[Northern bay]

Hey guys....So I've got a hydro leak in my pump (see pic). I can't locate the leak. Has anyone had similiar issues with this style pump? It appears to be coming from the bottom of the pump housing or even from one of the bolts behing where its coupled to the shaft.

bet its running down from the shaft seal, should be a fairly easy fix.

Just a thought, can you take some small pieces of paper towel or oil absorbent pad and place them around the pump to help try and track down the leak. I had a similar and this trick helped me find the weepy fitting.

makes most sense to me...just can't track it. I am trying to avoid taking it off the boat.

I've had them in place since it started! They get fully saturated.

As long as you are sure it is not a hose fitting leaking you are going to have to pull the pump and get it rebuilt.

Sorry buddy but no other way around it.

rebuilding it should not be that bad. A good hydro shop should turn it around in a few days.

That's what I was figuring on. It shocks me because there is not much time on it at all. Shouldn't these things last thousands of hours before a rebuild is necessary?

By the way is this Bill from LBI?

When used, we could just say it broke because it was used or old.:twisted: Now that we can finally afford to buy new, we find it breaks as fast or faster then when we used to get used or old.

I have seen the allen screw fitting on those pumps crack from over tightening the fitting that goes into them.Not my favorite type of pump.You have the pressure side reduced down 2 sizes at the pump.I take a small piece of oil rag and wrap it around each fitting and tape it there to see if its one of them.Most likely not the supply,with no pressure.If its the shaft the oil should be coming out towards the aft of the mount.Slide a piece of cardboard under the clutch and run it for a short time.

I had that same pump and from day one it leaked. I changed fittings and it still leaked. I just kept an oil rag under it and changed it when it needed it.

Hey Bill, Its Ted. Ben and I visited you in Sept.

Yes Hydro pumps should be very durable but like all machines they are just machines and subject to failure for a multitude of reasons. I suspect that since it is very low hours it had been flawed right out of the box. Improper machining of the seal surfaces is not that uncommon.

If you dont have a good hydro shop I highly recommend Beiler Hydraulics in Leola PA. Hydraulics, Pneumatics & Power Transmissions - Beiler Hydraulics, Lancaster PA

Pa dutch are masters of everything hydraulic.

They wont be dirt cheap but your leak will be history.
