EW duplex plunger oil pump
« on: 30 Apr 2014 at 12:15 »
Does anyone have the details of the two coil springs on either end of the mechanical oil pump plunger? The upper spring pushes a top hat against the end of the pump shaft and the lower one is the plunger return spring. I'm after uncompressed spring length, wire material, wire gauge and turns so that I can wind a couple. Thanks
