: My Jubilee will not lift at idle speed. At high
: rpm it lifts a box blade with no problem although
: it takes a long time before it begins to lift. I have
: rebuilt the piston pump. I have put new seals
: and o rings on the piston. I have disassembled
: the lift cylinder assembly and checked all valves
: for free movement. The oil is not turbulent when
: viewed through the access hole. Any suggestions?
I have two suggestions based on experience with my NAA. First, the lift linkage could be misadjusted. This is the linkage between the lever you use and the valve inside the cylinder lift housing. Mine loosened up and over time it got where it would barely lift in draft control (with the selector lever horizontal). With the selector level in the vertical position (position) control, it would lift better, just not all the way to the top of its capability.
The second problem I have had is the gasket between the cylinder housing and the cover blowing out. This decreases power, but it does seem like you would have seen oil spraying with the fill plug open.
I'd suggest you check the linkage.
