How do you loosen the crankshaft pulley of a Honda Civic 87 ?

Question

I'm getting frustrated trying to loosen the bolt of the Crank pulley. I try to block it using a screwdriver in a hole while using a wrench to loose the bold... and the screwdriver was bended ... suggestions please !

Answer 1

Heat that biatch up. Or get a very large pipe, slip it over your ratchet, and make those muscles work for you. Crank bolts are usually torqued down well over 100ft-lb. Or you can make your engine work for you if it's still in the car, get wrench on the crank bolt, position it against something sturdy like the sub frame, and turn the motor over. I would remove the fuel pump relay (if so equipped with said relay, otherwise use the appropriate method to relieve fuel pressure) and relieve fuel pressure before doing this so you can turn it over but not start it.

Answer 2

Don't use a screwdriver. Use a tire iron! The crankshaft bolts can be difficult to remove.

The best way to remove them is with an air impact wrench, but if you don't have one available and are doing it by hand (which is sounds like you are), Use a tire iron to jam the flex plate/fly wheel to keep it from spinning.

Or take off the starter motor and jam something through the hole to keep the fly wheel from spinning.

If you can get ahold of an impact wrench, Don't put anything to jam the fly wheel or that tool may come flying out. There should be enough resistance from the motor to not need to jam anything against the fly wheel/flex plate when using an impact wrench.

Answer 3

if you have access to air tools you'll need a 1/2in drive impact gun to remove this bolt. or find out which way the engine turns when cranked over, you need a long enough breaker bar to rest against the framing , position it where you want it, then bump your engine over and it should break the bolt loose. I hope this makes sense to you. good luck.
