Large diameter one-piece aluminum water pump pulley. This is an improvement over the 2-piece pressed steel pulley, which can separate at high RPM, and lighter than the original cast Cooper S pulley. This pulley is the same diameter as the Cooper S one, so it requires no change of belt size. Measures 4.72" diameter and 2.43" front to back. Thin fan spacer is built-in.
