    It would be best to replace both o-rings at the same time, if one is worn then the other might be on its way out too

Daisy Grizzly 840 won't pump up and shoot

Bad seals in Daisy bb and pellet guns cause this. Get the seals replaced in it and it will work. Look on the web for service on BB guns.

My dewalt 2 gal air compressor model D55141, when on hisses inside the pump housing. Sounds like a leek. Some pressure builds.

More than likely is leek. Must get to it to look at connections and air line to find out If slow probably would hear it. But loud you will find it. Tighten connections if it's there, other wise replace line

When riding my 2011 Yamaha grizzly 700 about 1/2 throttle it shuts down and when I get in water or mud it like it loses power what would it be

Hi Curtis:
Considering the age of the machine I'd be looking at basic maintenance first. Things like air filter, fuel filter, carb condition, spark plugs, oil and oil filter change. Then start thinking about valve condition and clearances.

Pumping does not build preasure, every pump leaks out, help

If you take apart the pump mechanism you will see a little black o ring that has dried out either Reuben or replace and add a little oil to the mechanism to keep lubed and it will work fine.

Gun fires weakly and sounds like air escapes after pumping

Sounds like you have a problem with either the valve leaking or possibly the piston head. I know by expierence that pumping the rifle more than once wont cause failure, so the issue here is not your fault. If the rifle is under warrenty then return it and get a replacement. If not then call Daisy and talk with their quality guy. He has helped me out a few times.

the water pump is behing a metal plate that you you would have to take off in order to look at it. if you have the 3.5 motor and are losing water then thats where it wil most likely be coming from,
