Mitsubishi Montero Loose or Broken Crankshaft Pulley Bolt

(40 reports)

The crankshaft pulley bolt may become loose or break causing loss of power steering operation and other related engine accessories. Some of these vehicles may be involved in a recall for this issue. Our technicians tell us that an updated bolt may be available. Replacing as necessary and properly torquing the crankshaft bolt will commonly correct this issue.

the roll pin holding the crankshaft pulley to the timing sprocket broke, probably due to loose crank bolt. -
This same problem happened to me when I bought the truck at 196000 miles for $600 bucks, and a thousand miles later the crank pulley pin sheared too, twice in little less than a thousand miles. The last time I was stranded in a busy intersection with my wife and daughter. To those out there experiencing the same problem try this, try to drill a second pin hole in the pulley at the same exact location but in the opposite side of the first pin hole, and instead of having one pin you now will have two pins holding the crank pulley. One on each side of the crank pulley,so that crank pulley can stay locked in place, but make sure you use the strongest thread locker.I think I have figured it out. This is just my idea to do it my self, but you can talk to a mechanic and see what they tell you. I am about to do that to my crank pulley hope I fix it for good, and I hope you too. 01/17/14 Eddy -
