Tim,
Wish you posted this before. I kind of suspected possibly cleaning it but was afraid of messing it up. I sent it back to Rapco who refused to warranty service it but gave me a discount deal on a new replacement pump. Tim Hickey wrote: ..... If you do not hear the vanes fall, they most likely are "hung up" due to some contamination. Open the pump, and clean everything. Put it back together. I use a little silicon seal to act as a gasket on the back joint of the pump. I think that the pumps fail when the vane gets sticky and refuses to slide in and out of the slot in the rotor. I know that the slots in the rotor will wear larger eventually, but I listen to my pump every 25 hours at the oil change and have had to clean the pump twice in the last 250 hours. The pump now has about 800 hours on it. ..... |
