My Power trim pump struggles to pump enough oil to raise the leg, when opperated the pump just spits oil from the outlets and makes a crackling noise a bit like its sucking in air.<br />When i do get the leg fully up, it is spongy i suppose there is air in the rams?<br />Ive stripped the pump and valve block and nothing obvious was wrong, infact it appears to be in perfect condition!<br />Im confused!<br />The leg drops ok but struggles to raise.<br />The ram seals are ok.<br />Any advice?<br />I see there is a repair kit available for these, but i dont know whats included.
