Derry Posted January 31, 2010 Share Posted January 31, 2010 Does anybody have any idea why my K4s keep reversing direction? They'll start up fine, and all is well for X amount of time. Then they'll spend the next hour chattering like crazy because the impeller keeps running backwards. What's the issue here? Quote Link to comment Share on other sites More sharing options...
JimD Posted January 31, 2010 Share Posted January 31, 2010 If they've ever been run on a wave maker, they could have sustained some damage. Try putting a piece of soft airline on the shaft nearest the screen to restrict the props forward motion, just dont snug it up. Quote Link to comment Share on other sites More sharing options...
+Hydro Posted February 2, 2010 Share Posted February 2, 2010 Most likely a worn impeller, I had some do that before Quote Link to comment Share on other sites More sharing options...
Derry Posted February 2, 2010 Author Share Posted February 2, 2010 Hydro, define "worn impeller," please. I can't see any visible signs of wear. Quote Link to comment Share on other sites More sharing options...
+Hydro Posted February 3, 2010 Share Posted February 3, 2010 Its the magnets that get worn usually, try replaing one and see if it fixes it. Since the impeller is the only moving part I'm quite sure that is what the problem is. Quote Link to comment Share on other sites More sharing options...
