Anyone ever have a problem with the crankshaft pulley coming loose?

Question

kept breaking belts then tonight found out that the crankshaft pulley was starting to come off,,any suggestions other than tightening it up?

Answer 1

Yes, just tighten it up. Engine rotation typically keeps these bolts nice and tight but most torque specifications are on the order of 145 ft.lbs for this bolt. The difficult part is keeping the engine from turning while you tighten the bolt! Engine rotation is typically counterclockwise which is against the tightening direction of this bolt as well. I have a special tool for my Hondas to keep the engine from turning... you may need a similar tool to torque it correctly.

Good luck!

Answer 2

A loose crankshaft pulley isn't unique to the Trooper, or to Isuzus, or, for that rely, to imported automobiles. however, i'd imagine that the Trooper promises an entire new measurement to the mechanic's bill.

Answer 3

BEFORE you tighten your pulley - take it off to be sure there is NO dirt/grease or burrs behind it-IF there is it will not tighten up correctely.Be sure there are NO cracks in the pulley itself also.Make sure the Harmonic Balancer is tight also.IF the pulley is rusty , it will wear belts out , faster.

Answer 4

that's all you can do is tighten it up,,if you have had the car worked on lately,,they might have had it loose and not tightened it back up right,,it,s a good thing you caught it when you did,,if it had come off it would have ruined a lot of good part,s,,plus it would have left you stranded somewhere,,i hope this help,s.,,,,PS try putting some lock tite on it,,this will keep it from backing back out.

Answer 5

Use a torque wrench and set it where it needs to be .But use THREADLOCKER BY PERMATEX on the bolt the blue with hand tool the RED you need to use a torch to heat up the bolt for removal.

Answer 6

I've seen it happen on a Chevy deisel. Maybe get some locktight on the bolts....not too much though. Good luck.
