Mitsubishi Repair: Removing Crank Pulley, ft lbs torque, crank pulley


Question
How do I remove a crank pulley on a 2002 Lancer 2.0L Engine I cannot immobilize the crank and cannot jar the bolt on the pulley free, any suggestions?

Answer
Leland,
I don't know specifics about the Lancer setup, but most are similar.  For stuck bolts, the first thing you'll want is to soak the bolts with some good penetrating oil.  I've had good success with PB Blaster.  Spray down all the bolts and let it soak in for 15-30 minutes.  Then soak them again for another 15 minutes.  The longer you let them soak, the better you'll be.  Take note that you'll want to be very careful to not get any of the oil on the any of the drive belts.  Cover the belts and wipe them down really well after spraying.  

If the crank bolt holds both the crank pulley and crank sprocket, then there is probably 80-95 ft-lbs torque on it from the factory.  It'll take a lot more power to remove that.  If you have pneumatic tools, you should be able to remove it.  Else, you may need to get clever to remove it (not to mention to reattach it to proper torque spec).  If you cannot hold the crank bolt, your pulley may have a hole that allows you to screw a bolt into it to keep it steady.  If you can screw a smaller bolt into the pulley, you can get a piece of strap metal, screw it one end to the pull and bolt the other end to some secure place on the engine block.  This will allow you remove and reattach the crank bolt properly.
Good luck!
