This is a new to me
boat and I am learing lots. First order of business has been to clean and clean and then clean some more. The boats
water pump has worked well until today.
The
pump model goes on to say 12volt, 5 amp, 2.8 gpm. It also lists the initials ITT and the name
Jabsco Products.
So the
pump suddenly began to run with no
water coming out of the faucets.
Inspecting it I see a
motor turned shaft that has what basically looks like the arm of a piston that is part of what appears to be a rubber diaphram on the top side of the pump housing/body.
The
motor shaft has a set screw that I think would or should set against the flat side of the motor arm thereby securing the "piston" arm to the shaft that would accuate the diaphram and deliver
water to the faucets.
When I turn on the switch- the motor continues to run but the diaphram arm does not accuate and no water is delivered.
Any thoughts as to what is going on? The set screw was tight on
inspection. I have since loosened it and am wondering if it somehow became no longer "set" to the flat side of the motor shaft. In my limited time I had I really could not find the flat spot to try and reset the screw. I have not removed the pump as I was out of time. This may be the best approach and when removed I should be able to set the screw and also
service the pump if needed. My concern is - could there be more trouble inside the diaphram ?
Any
advice is certainly welcome.
Thanks Randy
