The EZNoseLift is lubricated internally and should need lubrication only after 1000 operations. The unit can be removed from the aircraft in approximately fifteen minutes by removing the NG3A pivot bolt and the two upper AN5A pivot bolts and lifting the unit out the nose access door.  The actuator then can be disassembled for lubrication of the ball screw by removing two socket head cap screws. The taper roller thrust bearings can be lubricated by inserting a grease zert in place of one of the mount bolts and forcing grease into the bearings with a grease gun. The lower part of the actuator houses the shock spring and the recoil o-rings. These should need no maintenance and should not be disassembled because the spring is under preload.
