We just moved into a different house this weekend, and last night I wanted to use the sprinkler system to water down some roses we put in this weekend. Well, I started the system up and everything looked great but ONE thing. I have a turf type rotor that will turn, but once it reaches either end of it's rotation, will not go the other way without some manual encouragment.

I don't have the part # right now (can get it tonight), but I wondered if there was something I could tighten up to make it function properly or if I was going to have to replace the head. This is a rotor that is very similar to the Series 5000 Rainbirds that I had at the last house. The system was installed about 12 years ago if that helps...

I can get the exact model # tonight.

Thanks for any help!
