Loose fan hub

[scagle1]

hey guys got a question for yall, I heard a slight bearing like sound from the front of motor and found the fan hub pulley is loose.I can move from top to bottom a little bit when shaking on it.The four bolts holding the drive pulley all seem to be tight.Is there a piece under this that i need to replace or is something else just loose?

Are you sure its the fan hub or the water pump? Isn't the fan attached to the water pump? I can't remember. Water pump bearing might be shot.

Sounds like the clutch is going bad.

fan clutch or water pump hope for the pump though because its alot cheaper

Yeah i believe it is attached to the water pump,but i dont know which is bad.I can grab the fan blades and wiggle the whole mount.Have never had one apart yet and my diesel experience is limited to working on 60 series detroit. Have shown no signs of overheating though or running hot at all.

I'd get er fixed right away. You don't want that bearing to completely go out and either smoke your belt or worse shoot the fan into the radiator. That would be messy.

will do it's sitting till fixed just found coolant leaking down from behind the pulley so i am guessing the water pump.

Water pums aren't too hard to replace. The impeller fins on my 95 were worn real bad and it wasn't circulating very well and mine never did overheat. I don't know how though.

yep thats probably what it is. There is a write up on here to help you if you need it. Also check on youtube. There is a video from maintain of a water pump install in a S.D. 7.3. Here ya go i found the link to it. YouTube - Water Pump RnR

Appreciate all the help guys, got the new pump in the backseat and am bundling up to go fix her. If powerstroke.org was a person it would be my hero.
