How can I counteract the torque on the crank shaft?
The torque provided through the drivetrain will be more than enough to counteract the torque put on the crank hub bolt. If it’s a front wheel drive, have someone stand on the brake pedal, or wedge something onto the brake pedal to hold the front rotors still.
How much torque do you need to crank a car?
It seems I have to replace the oil seal at the pulley-side of my crankshaft. According to the technical manual of my car, the central screw should be torqued with 120-145Nm. I don’t know how much torque is needed to crank my motor, but I guess that 120-145Nm is enough. So, how do I prevent it from cranking?
Which is higher holding torque or running torque?
Holding torque is typically higher than running torque, and is limited primarily by the maximum current the motor can withstand. From a practical standpoint, holding torque is the sum of the magnetic force exerted by the coils to hold the motor’s current position, plus the detent torque.
Why does detent torque have to be overcome?
Because detent torque has to be overcome before the motor will move, it reduces the ideal torque the motor can produce when it’s running. The amount of power the motor needs to produce to overcome the detent torque is proportional to the motor’s speed.
What is the correct torque setting for the crankshaft bolt?
What is the correct torque setting for the crankshaft bolt? is it a stretch bolt and is it left or right hand thread? Clicking this will make more experts see the question and we will remind you when it gets answered. You can’t post conmments that contain an email address.
How to lock the crank shaft while torquing central?
If it’s a front wheel drive, have someone stand on the brake pedal, or wedge something onto the brake pedal to hold the front rotors still. Another way, if it’s not a manual shift tranny, is to take the starter out. Then using a long, stout, flat tip screwdriver, find purchase against the starter ring teeth.

How do you keep a crankshaft pulley from spinning?
Depending on the type of car there may be holes where you can thread bolts into the crankshaft pulley. Then you could use a prybar or something to keep the pulley from spinning. – Ben May 8 ’16 at 18:48 If the vehicle has a manual shift transmission, put the transmission into the highest gear, then set the parking brake.
