Back on the 16th. I posted about my deliema with two 8N's that have to sit for long periods and the hydraulics now will not hold/work.Several have given help so I'll post where I'm at.Turned warm today so I put a load on one and went through the check list process.The ram piston pump was redone and neww piston and neoprene washer's.All checks well with no leaks under load but ????I have some oil movement at the lower hydraulic pump.I can see part movement and I believe the oil is just this.Now,,,,I have the lift up and holding for 1hr. now.Said a prayer also.As someone has said I put pressure in through the oil check.Can't believe the unit wasn't primed.I've never rebuilt a pump so,,,,maybe I'm safe.
