lift issue

rob07 · Apr 6, 2012

Have a question on my 861 rebuilt the lift on it a few months ago rebuilt the pump,all new seals and gaskets and new seals in the lift cover and it works good for about two weeks can leave sitting for a couple of days still works greats but about two weeks later have to bleed it again to get the lift to work again any thoughts anyone run in to this before? any help would be thankful.

It is common for the shaft to have a groove worn in it where the seal rides. If yours had a groove and you didn't repair it the pump will loose it's prime do to air getting by the new seal because of the groove.
