560xp oil pump

[Dilz]

been getting nothing but grief from my 560xp and its oil pump. 

 

I've cleaned the pump and flushed the tank a few times yet it still keeps fouling up after a few hours. Haven't cleaned it since it last stopped working about a week ago. Wondering if i should just try a new pump on it?

Are you sure the worm gear isn't buggered?

Check the worm gear has not damaged the plastic part it sits on the pump had one that melted part of the plastic to the spinning part of the pump and it would work sporadically

Will make sure to check it when i take the pump off this time.

Sounds a bit weird, if the tank is flushed, the pickup line and filter are clean, the pump gear spins freely, the oil pinion worm isn't stripped or damaged, the pump inlet and outlet are free, the oil channel to pump channel is clear....there is little else that can fail.

I have seen melting between the pump and worm but if all this is OK, it is unlikely no oil will flow. Just make sure it isn't just down to cold weather and thickening of the oil.

One last thing, check the oil tank breather is clear of crud.

What year is your 560? If all the above checks out have a look at the oil hose they used to close up and limit oil supply especially in the cold. There was a re design of the oil hose to prevent it.

check the fitment of the pipe which oils the bar where it connects to the pump, found a split in it causing problems , ive had a few fail here over the years and also the brass filter in the the tank once was clogged up with fine gunk
