thank you for the replies. now, i know that the unit is no good(the pump at least), and will have to buy a new one.
My boss had siad to me that his plow kept turning left when he tried to raise it. upn inspection,found 2 of the three studs which secure the pump cover to the base came loose, and one of the stud holes snapped off inside the pump.
This problem arose while it was still snowing. fortunately, we had a complete back up E-60, and just switched the entire unit over to the truck which had this problem.
