ISX fan clutch

[Rawze]

Someone came to me with w pete that kept overheating once and burning up clutches. The fan solenoid air lines were plumbed backwards from the factory. It still worked, but the clutch kept slipping after a while.

Could be a bad fan solenoid?.

Have seen them stick partially open or not opening all the way
Also check air supply to the solenoid

Will do. Thanks!

Okay, found squealing sound. Bearings on air conditioner belt tensioner completely shot. Question is and maybe kind of dumb one but would that cause the fan clutch brake pads to have went bad so quick. Remember, It went bad after only about a month and had to rebuild

To completely wear the clutch fiber that quickly it would have to be an engagement issue of some sort.
If the clutch is fully locked, or fully disengaged there is no slippage to cause wear.
Air pressure, Improperly assembled, insufficient travel to fully lock, Etc.

I would think not normally, but then again,... if the belt suffered excess vibration, it could have transferred that vibration into the clutch pulley and worn the pads prematurely... Kinda makes it a possibility?.

Well, if I remembered correctly, I heard high squealing sound prior too both failures. Going too Give it a try. So at least I know they can be rebuilt easily and cheaply now.
