    Solenoid is fine. Comes from the factory that way. The sprayer or reel needs a good ground to the truck frame--otherwise pushing the reel button will have no effect.

    It's not too bad. Got a 1/4" of dust on it from sitting in a building. Got to start somewhere I guess.

    Took pump off motor today. So the regulator is the only other thing I need to buy to fit the d30 on. Looks like from reading many post most say go with the d30.

    Potentially you could reuse the regulator.
    Does the old pump have 3 pistons and diaphragms, meaning its a Hypro 403?
    Or is the old pump a D-30? D-19?
    Possibly the diaphragm got a hole worn in it--so the oil (SAE-30) and water mixed together. Lubrication from oil is minimal after that. Perhaps this caused the crankshaft bearing to fail. Instead of fixing the diaphragm, someone kept using it even after the milky-brown discolored oil was plainly visible in the oil sight glass. Voids the warranty--$1000 mistake.

    It's a 403. 3 piston. Up in the air about which one to go back with.

    Thanks. I don't mind spending the money on the d30 and regulator if it's going to be a better pump.

    The Hypro D-30 is a great choice. I am happy with them for over 25 years.

    Change the Pump Diaphragms and the regulator relief valve seat as well annually. http://www.rittenhouse.ca/asp/Product.asp?PG=654

    Enjoy the new pump.
