DanielODell Posted November 27, 2018 Share Posted November 27, 2018 Hi all, im new here looking for more wisdom than I have. I have a 2006 granite that keeps eating fan clutches. The main hub bearing are good but when the fan is not engaged it’s spinning real slow and it’s real sloppy. This is the 2nd one in 60 days now. These hubs were purchased from local Mack garage but are not genuine Mack. Looks like I’m gonna be changing another one very soon but I’m going with a genuine Mack hub this time around. I’ve replaced the fan and the air control switch still works perfectly. My question is.... has anyone else ever had this issue? Am I missing somthing or doing something wrong? I’ve changed several fan hubs but this has me stumped Quote Link to comment https://www.bigmacktrucks.com/topic/54901-fan-clutch/ Share on other sites More sharing options...
Mackpro Posted November 27, 2018 Share Posted November 27, 2018 We have zero issues with the Horton 2 speed air fan clutches on the AI CV’s like yours. Wonder what brand they are selling you?

Mack Technician Posted November 27, 2018 Share Posted November 27, 2018 (edited) Previous owner of the '05 CV713 was killing clutches and switched to electric logic fan with no further issues.
