Question by: Glen H on Nov 12, 2025, 8:40 PM
part number 70421-318, is that the back plate assembly for the piston pump or just one piece of it?
Answer by: Customer Support on Nov 14, 2025, 8:35 PM
That part number covers the full back plate assembly. It ships as a complete unit, so you're getting everything that makes up the BK plate assy in one package. Sold individually, one assembly per unit.
