1993 Ford Mustang Convertible Other - Engine

Question: Trying to remove bolt on front of crankshaft. Have crankshaft locked so it will not turn. Even with a breaker bar and cheater I cannot get the bolt loose. Any ideas? Please and thanks!

Technican: Soak the bolt with PB Blaster. An air impact wrench is the preferred tool. You will need a powerful 1/2 inch drive impact. Can you borrow one? Keep in mind a $40 dollar one probably won't cut it. Try to get an Ingersol Rand, Snap-on, Bluepoint, Craftsman, etc with at least 300-400 ft lbs of reverse torque. Only use an impact socket with an impact wrench, normal sockets are glass hard and can shatter... I wouldn't recommend other bolt loosening procedures such as heating the bolt or rapping the bolt with a hammer prior to removing. Another method I recommend against- Some people block the breaker bar off (ie against the frame) and use the starter to break the bolt loose. This method can be dangerous (especially if misjudgement is made determining wich way the engine rotates). This method can damage the starter/ teeth/ etc.

Owner: Sorry the problem is solved. I extended the cheater and rapped the base of the cheater with a hammer. It finally came loose. I appreciate the tip to use PB Blaster but I had already done so. This bolt was in excess of torque specifications by many hundreds of pounds. The torque spec is 115lbs and I could not measure the pounds on the bolt because my torque wrench stops at 140lbs. I was beginning to think the bolt was left handed, which I have never seen before. Oh well, the problem is solved, but I appreciate the reply. Keep the money, I appreciate the tip.

Technican: Good job, that is the same idea as an impact wrench... the hammering action. Is your car up and running?
