Thanks for the help, guys. I replaced the inoperative ones with 5004's and everything is good to go. The adjustments for the 5004's are considerably less difficult than the old T-Birds. Thanks again!
Thanks. Do I need to replace the entire assembly or can I just swap the guts?
I have an old sprinkler system in my yard and it has T Bird rotors from Rain Bird. Since the T Bird isn't made any more, what can I use to replace the ones that aren't working. Thanks.
