Oil Pump Help

[Dave Willis]

07 6.0 with 108K miles
Pulled oil pump cover, inner gear broke in 3 pieces, Keyed to the crankshaft in 2 places. Bought a new kit that included a new front cover, oil pump and all accesories. Reassembled everything, attempted to start and engine seemed tight then started turning over fast, still no start. pulled cover off oil pump inner cog broke again in 3 places.

Any help appreciated.....Dave

Find any metal in it not from the pump itself?? Roller bearings?

[Dave Willis]

Oil and Filter was changed before pump rebuild. Only thing inside the pump was the three pieces of the inner cog. No other foreign material was detected.

Thanks.....Dave

I guess it's time to pull the oil pan off to see WHAT caused the inner part of gerotor to break into three pieces.

[Dave Willis]

Other than metal in the pan, that could be locking up the pump, is there anything else I should be looking for?

Thanks.....Dave

How difficult is pulling the oil pan?
Why is the center cog keyed and there are no keyways in the crankshaft only flats on both

Thanks.....Dave

Pulling the oil pan only requires removing the engine mount fasteners, and jacking the engine up about a 1/2" to give you the clearance needed for the pan to slide rearward far enough that you can access and remove the oil pickup. Once removed, slide the pan rearward the rest of the way out.

lifter come apart????

[Dave Willis]

After the new pump install, the new pump didn't turn over enough, before breaking, to pump oil into the pump housing. When tore back down, the white lithium grease was all that was in the pump housing, and of course the broken cog. No oil. So my question is, anything in the oil pan is not an issue at this point, correct?
Also, again, why is the inner gear keyed and the crankshaft is not?

Thanks.....Dave

Offhand you may have been given the wrong rotor. If there are no flats on it how are you even getting it on the shaft?
