Oil Pump failure

[KE4AVB]

Just anyone else ran into a Georotor locking up a Briggs 310000 series engine? I currently replacing one that hangs hand turning through. The engine came complete locked up which I manage to free up with both hands. Also found a severely worn oil slinger/governor gear. Unable to find any other reason for the lockup.

That is unusual. How many hours on the engine? Is it lack of maintenance or did something come apart and contaminate the oil?

No hour meter but the engine is a 2007 model. Oil was recently changed. But I have checked the crankshaft journal just the engine was ran without or with polluted oil, no sign of any damage. The thing I think of is if something got into the rotor at that extra place and jammed it.

I would have thought it would be wear but one place shows that it is bottoming out. It is just hanging in that area. Normal wear marks on one side. It is just like the metal has swollen.

New Georotor was fairly smooth hand turning though several complete turns before installation.

Never came across that problem.
