Groco Oil Change Pump Rotor/Impeller
Seeing if anyone has experience with the Groco oil change manifolds/pumps. The one on our Hatt is a BMX 3-80 and it has a plastic rotor (what Groco calls it) that actually pumps the oil out of the oil pan on our Detroits. The pump stopped working recently and I found a crack in the rotor that mad it no longer pull prime and pump oil out. I found the replacement parts (picture attached but the rotor has 8 vanes instead of 4 like the one that is in my pump. Wondering if anyone has the same pump and had to replace the rotor. Does the 8 vane rotor work as a direct replacement part for the 4 vane version?Thanks!
