2003 montero sport crank shaft pulley pin?
 

My belts keep slipping and I finally discovered the crank shaft pulley bolt was responsible. The bolt continues to loosen. I had it tightened to specifications but still loosens. I noticed there was a small hole in the pulley and have read that a pin belongs there to stop the pulley from turning. Is this true? If so where do I find it because it isn't offered with the pulley? Is there a new bolt that is offered because of so many previous recalls? Ill never buy another mitsubishi. Too many problems.

anyone?

its a roll pin you know any hardware store

Hello Everyone- I'm having the same issue with my Montero Ltd. My crankshaft bolt keeps getting loose and i'm suspecting its from the roll pin to the damper pulley - took it apart and notice the roll pin is sheared off.

Anyone have any thoughts to the original post about the pin?

Thanks
