  • Qiet a ways from me lol. My buddy and I put the original cylinder back in my naa. We used a different piston. And it works. We left the lift arms up over night and they stayed. All I can think of is that my piston o ring was bad and that’s why it dropped. How ever the reason it wouldn’t lift with the other cylinder still plagues us. The unloading valve ( newer style ) did stick in the rear position of the bushing. That may have been part of the issue. One thing we noticed on the unloading valave there is a “sleeve” that is pressed in to convert to the new style, on the sleeve is a flattened are the seems like an oil passage. Is that position specific?
    New question, my control lever doesn’t begin to work until it is maybe 4” from the lowest stop. With the control arm in the up most position the lift does not reach its full height. I believe I read someplace I can loosen the nut on the control leaver retainer and rotate that to get the full range of the lift. Is this correct?

  • Can't function with sticking unloader valve. Not familiar with, " a “sleeve” that is pressed in to convert to the new style".

    I believe I read someplace I can loosen the nut on the control leaver retainer and rotate that to get the full range of the lift. Is this correct? ' No, it is not, because the lever/disk that it is attached to will be keyed to shaft. Not reaching full height is most often related to worn cam follower pin or under the cover linkage adjustments.

  • Would that be the valve (hydraulic lift control) adjustment?

  • In the picture (which is not exactly your NAA, but similar), in the middle center is an adjustable link between control valve and the control arm AND at lower right there is a hex at the end of a spring on the position control linkage. Both can alter the height of lift.
