+ | ====== Priming the Oil Pump ====== | ||
+ | A dry pump won't pump oil. \\ | ||
+ | It will 'cavitate' when their is not a hydraulic seal between the gerotors and the inlet hose from the tank. \\ | ||
+ | |||
+ | Any time you have removed the oil pump or the removed / drained the feed hose from the oil tank, the pump needs to be primed. \\ | ||
+ | * The oil pump needs to be primed with oil / lube before it can transfer oil from the inlet to the outlet cavity inside. | ||
+ | * Prime the oil pump per the FSM; | ||
+ | * Upon removal / inspection, oil the pump internals. | ||
+ | * Remove the oil pressure switch and rotate the engine until oil comes out the end of the pump and reinstall the switch. | ||
+ | * If you let it sit long enough, oil will gravity drain inside the pump and prime it. | ||
+ | * Another way to prime the pump is to use assembly lube on the gerotors and inside of the pump before installing it. ((aswracing of the XLFORUM http://xlforum.net/forums/showthread.php?p=4805186#post4805186)) \\ Then you have an instant hydraulic seal to help the oil pump suck oil from the hose. | ||
+ | * You can also using a large syringe with a tapered tip inserted into the oil supply hose on the bottom of the oil tank. ((ericfreeman of the XLFORUM http://xlforum.net/forums/showthread.php?p=5751479#post5751479)) \\ Then you can force feed oil the pump and on to the engine using this technique and it avoids having to mess with the sending unit. | ||
