    Not sure how to post pics but this is the second time this has happened . I have a Meyers e47 pump and the three studs that hold the pump toghter break off and blow out of the unit ! First time I was at work and truck was on hoist and was close to heater stud blew out and landed on floor . This time it's -6c outside and I went to lift plow it was half way up than slammed back down . I went and looked and two studs are gone . I don't get it . Why is it doing this ?

    Overtightened, too high pump pressure, clogged vent cap or fatigue.

    yup. the plug you remove to fill the tank is supposed to be vented. it either has a very small hole in the side or a venting stone in the top of the plug.

    ???? It has to be vented. As fluid leaves the reservoir to go to the cylinders, the fluid level drops. Without a vent, the reservoir would go into a vacuum and the pump would cavitate do to lack of fluid supply.

    By looking at the lift arm it appears to be an ez classic mount which should be an E47. To be sure just measure the size of the reservoir can.

    No. Not necessarily. Unimounts and conventional pumps don't
