i think pump motor is locked can i get to it to turn shaft
TRYING TO OPEN COVER FOR REAR ENGINE TURNED
I take it that it's tripping the overload (OL) on the motor. To answer your question, there's no way to externally "turn" the motor/pump in an attempt to get the pump to break up a blockage. Motor power is the only way. If it's tripping the OL, then there's likely something in the pump seizing it up. Ninety-nine percent of the time, that's the issue.
To determine whether the motor is the issue or if it's the pump, you'd need to first remove the pump from the motor. Then, run the motor. If it runs freely, then the you'll probably find the pump's shaft won't turn even with a small adjustable wrench. If it won't, don't force it. It's got debris in it and you'd need to disassemble the pump to get that out and clean it all up. If you do that, get ALL of the crud out it so there's absolutely NO foreign material in there. Then reassemble it with all the parts wetted down with fresh, clean fryer oil.
HOWEVER - when you separated the pump from the motor and found that there's oil buildup at the coupling between the motor and pump shaft, then the pump's shaft seal is leaking by and allowing oil migration into the motor windings. If that's the case, then both the motor and the pump need replaced.
I'm not certain about Pitco, but in some manufacturers offer a rebuild kit for the pump, which includes o-rings and a new shaft seal. That can save a bunch of money for not having to replace the pump outright. Mechanically, pumps can last forever, so the metal parts are fine. Usually the shaft seal is what makes them fail and require their replacement.
WHAT CAUSED THIS?
FYI - If the filter system on the fryer wasn't set up properly by the user (which is a common issue), then the close tolerances within the pump won't accommodate "crumbs" in it. It's EXTREMELY important that the filter pan be free of ANYTHING (very clean) before filter paper is installed prior to filtration. Additionally, the weighted hold-down ring should be installed in a manner to facilitate proper sealing the filter paper down around its entire perimeter so that NOTHING except filtered oil gets past it. Anything that get past it (like a crumb) can possibly seize up the pump.
