mack fan clutch
I drive and work on dump trucks mostly macks ive been having a problem with the fan clutches going bad . there air operated fans . ive tried changing the soleniod valves and everything but they just keep wearring out. About once a year i have to replace one. The cost to change the clutch is almost a thousand dollars and mack wont warranty this because were sitting on construction sites with the air running so the clutch just keeps kicking on and off . wearing itself out prematurely does any one have any sugestions for me. thanks

Re: mack fan clutch
I am assuming you have checked to ensure you don't have a air leak to the fan. That will cause premature failure if it exists.
If that is ok, possible change to a different manufacturer of fan clutches, and go that route. That might get you at least a year warranty on the part itself.
The last option is to convert it to an electrical one. That might require a little parts shopping to match everything up.
