Claim 16:
17. A sprinkler assembly comprising:
an inlet;
a bracket connected to the inlet;
a nozzle in fluid communication with the inlet and positioned downstream of the inlet, the nozzle configured to direct water out of the nozzle along a nozzle axis;
a deflector assembly downstream of the nozzle and configured to move with respect to the nozzle axis in one or both of a rotational and a tilting direction about a pivot point, the deflector assembly comprising:
a distribution plate configured to deflect water from the nozzle,
a spindle extending from a side of the distribution plate facing away from the nozzle and terminating at a distal end, the distal end comprising a receptacle,
a bearing insert disposed in the receptacle,
a wear sleeve carried by the spindle, and
a weight carried by the spindle and having a mass selected to adjust or change a rotational speed of the distribution plate,

a bearing supported by the bracket and contacting the bearing insert at least when the sprinkler assembly is at rest to bear substantially all of a weight of the deflector assembly; and
a housing supported by the bracket and comprising a surface configured to contact the wear sleeve to limit movement of the deflector assembly in at least one or both of the rotational and the tilting direction about the pivot point, the housing defining the pivot point when the sprinkler assembly is in operation,
wherein the spindle extends further downstream than the weight.
