Thread: opinions please

Depends what crc you used. 556 or brakleen are not for belts. If the dealer meant belt grip they should have said so.
I don't think the fan would have broken first.

That belt grip is amazing. It turns an old squeaky belt into a mess that takes ages to clean out, and still needs another belt

originally breaklen was basically dry cleaning fluid and just dissolved oil and grease. i used to buy the pure stuff and use it on belts/rollers/ etc in cassette decks and turntables (look it up you young guys)
then it turned into a detergent based product.

We used to put golden syrup on the belt drive of the overhead shaft driven shearing plants if they were slipping. Then later on in years you could buy cardboard wrapped tubes of some sort of hard silicone stuff that you put onto the belt when it was running.

My 2 cents . I would say there was possibly damage already. Spraying things on belts to stop squeaks is a temp fix imo. If its squeaking that's your warning .

Just to clarify. The pulley was sprayed with CRC 5-56 Marine, not the belt itself.
It stopped the squeak in a nano second, which is why I dismissed it as a minor

Yeah pretty evil shit. Main ingredient was tetrachloroethylene, not something you want in your eyes.
When we were manufacturing the brakleen 600g aerosols they would have 586 grams of liquid product in the can then had 16-18 grams of CO2 gas pressed into it. That CO2 was around 300cc and if it wasn't warm enough it would be a liquid instead of gas and the cans exploded in the filling machine rather spectacularly.

If it was squeaking probably the belt was on the way out....the 556 definitely finished it.
Don't spray 5.56 on belts....it's a lubricant.....and it fucks the rubber.
If you sprayed the pully you sprayed the belt...same same

Yup what Cam said
556 destroys rubber in no time

If the belt disintegrated most likely it would have simply exited stage left and would not have had anything in it to catch a fan blade to destroy anything.

More likely scenario, is it simply threw the belt which got hooked up between the sensor and the fan blade which destroyed both at the same time. If the pulley/belt is squealing, the cause could be worn belt, worn pulley, buggered tensioner, stuffed bearings, misalignment, stretched belt meaning low tension, or something more arcane. Either way, a dealer saying squirt it with CRC is a dealer who doesn't want to spend any money on fixing it properly and hoping you'll go away - duty of care issue as I think someone else suggested.

Mate, get the old belt back, I recon the fan will be plastic, a blade will never in its wildest dreams have enough kinetic energy too slash a reinforced fan belt. IF the fan broke, centrifical force would have shot/trown it away from the fan and the belt, if it hit something and got directed back into the fanbelt the kinetic energy would have been even lower so the chances of the blade slashing the belt will be very low.

If by some magical event the blade managed to lodge itself behind the belt and then ended up pushing against the belt wearing it down, you'll see some pretty clear wear marks on the blade. Inspect the blade.

Fanbelts squeck for 2 reasons: misalignment and slippage.

If I were to quess what happoned Id say the belt failed, got pulled in by the fan, snapped the blade and either the blade that shot away or the loose hanging pieces of the belt wrapped itself around the sensor and ripped it out.

Golden syrup on the overhead shaft drive brings back memories of some awesome times for me.
Sorry it doesn't help your problem Pengy.
