Rotation of Crankshaft
Why!! Why!! Why the crankshaft does not rotate in ccw direction? Can it be rotated in ccw direction? How?

Ramani AswathWhenever normal right hand threaded parts are involved, rotation is in the direction that will tighten the screw as otherwise some thing may get unscrewed often with hazardous consequences.

what screws are you talking about. i dont think there any threaded joints in the crankshaft.bioramaniWhenever normal right hand threaded parts are involved, rotation is in the direction that will tighten the screw as otherwise some thing may get unscrewed often with hazardous consequences. -

if you wish to switch the direction of rotation for a crankshaft with equal firing angles, you will need to re-adjust its cam timing. there are probably a lot of other things that go with it as well.gowthamanbuWhy!!

Not in the crank shaft. Any right threaded connection in the drive train will see the engine torque. Such a connection can work loose.zaverii dont think there any threaded joints in the crankshaft.
However, many of these are by convention. The first one starts that way and others blindly follow suit. -
SaugataOne of the reason is, when you start an engine the motor rotates the flywheel in a particular direction; generally clockwise direction and after gaining the momentum in that particular direction it continues to retain its state of motion as the engine starts.

NAVATHE SACHINI think crankshaft is connected to cam and cam is connected to vehicle tyres.If the crankshaft rotates in ccw direction then cam and vehicle tyres also rotates in ccw direction.If it is wrong correct me....

the crankshaft is connected to the vehicle tyres via the flywheel, clutch, gearbox, propeller shaft, and differential.N.SACHINI think crankshaft is connected to cam and cam is connected to vehicle tyres.If the crankshaft rotates in ccw direction then cam and vehicle tyres also rotates in ccw direction.If it is wrong correct me....
The camshaft is a component of the engine, and it is used for actuating the valves. it is driven by the crankshaft too. -

What does that has to do with it? What if we start the engine with crankshaft rotating in ccw direction? The flywheel will also rotate in ccw direction and won't cause any problem.SaugataOne of the reason is, when you start an engine the motor rotates the flywheel in a particular direction; generally clockwise direction and after gaining the momentum in that particular direction it continues to retain its state of motion as the engine starts.
Here we are not talking about changing the crank rotation while the engine is running.
ramani sir's explanation is the only correct answer.
