Where do you see the torque value? I am almost sure you are mistaken. There is no big bolt on the flywheel. The rear seal has m6 and m8 bolts. The front crank does require high torque but using an air impact won't give you that.

The m40 has the flywheel bolts
torqued to 105nm and the crank bolt on the front is torqued to 320nm

thx. 105nm is a bit difficult to achieve by hand with the car on jacks on a turning flywheel.Originally Posted by Bill R.
isn't there any other tool other than an impact wrench?
what people are using?

Actually no it isn't hard to obtain.
you can lock the flywheel from turning with any number of things, put a socket of the front pulley to hold the crank from turning. And use a long breaker bar to break the bolts loose,76 ft. lbs isn't that bad. Now the front crank bolt is alot more fun without the right tools.

which tool will give me high torque for the front crank bolt?
