Removing Broken Belt Tensioner
Hi folks, I'm in a little bit of a bind. I was replacing the belt on my 335, and the T60 thread on the tensioner pulley stripped out, so I can't compress the spring any more. I went ahead and bought a new tensioner pulley setup and was just going to replace the whole assembly, but when I went to remove the old one, I realized that the little tab that stops the spring from completely uncoiling (circled on the picture below) has literally sheared off.
At this point I'm completely stumped.... I can't compress the thing the normal way to get it into the service position, and I can't take the whole thing off without risking the spring fully uncorking and doing some real damage. I have the fan off, but I still don't really have enough room to get any sort of pry bar in there to try and compress it the old school way. Any ideas? |

Just take it off carefully. I busted off the T60 fitting trying to loosen it the wrong direction. Ended up just unbolting the tensioner at full tension slowly and nothing flew off.

I then un-bolted pretty much everything that I could: The pulley right next to it, the oil lines going from the cooler to the filter housing, and the coolant line going to the filter housing. After getting all of that off, I wedged my crowbar back in there and tried to let the tension off as carefully as I could. It went about 1" further than it had been and completely fell apart harmlessly. Crisis averted... no major damage. |

Thanks for the update. Does anyone know which way you turn the wrench to relieve tension ? If you are looking from the fron is it towards the driver or passenger ?

I took the easy road ( I think you guys were trying to over think this).
The torx female notch in the tab piece for relieving pressure on the belt stripped in my case. I tried all kinds of tools and levers but couldn’t ease the pressure on the belt. Solution: cut the belt. I figured, what the hell, I’ve got a new belt and a new tensioner to put back. |

Random O Ring
Me being the idiot I am snapped part of the tensioner by trying to "loosen" the tension counter clock wise. I am about to put in the new tensioner but theres a random tiny O Ring that came with the tensioner kit. Where do I put this tiny O Ring?

Between the engine and tensioner on the bolt. It helps hold the bolt in place so they don't fall apart while installing.
