You are purchasing a Basic Seal Kit 15707 for an E-60 Meyer Snow Plow Pump. This is a good deal, as it includes all you need to remove the top cap on the pump, and change the wiper, and O Ring seal under the cap, and the lift ram packing (included are both the large and small packings), lift ram base O ring, drain plug O Rings, Filter Plug O Rings, 3 white Nylite washers that go under the three nuts (3 new nuts are included too!) on top of the cap to seal the studs, and the tank O Rings. It also includes the pump shaft seal, and the motor mounting plate O ring and two nylite washers. If you never had the motor mounting plate off your unit, you will not believe the gunk you will find inside! Everything you need to get 99% of the gunk out of your E-60 unit. Download the E-60 Service Manual off the Meyer web site for FREE to assist you. *The difference between a Basic Seal Kit and a Master Seal Kit is that the Master Seal Kit includes all the Valve O Rings.* MADE IN THE USA
