How to lock the crankshaft?


I am trying to change the timing belt on my car, well my father is.

However he cannot get the crankshaft to stop turning? How does he lock it? Does anyone know?

Stick it in gear and get an assistant to jam their feet on the brakes. Best done with the wheels on the ground so you don't drag it off the axle stands.

No need to. If you've slackened the cam pulleys, there's enough slack in them to reset TDC after routing the belt.

If that fails, the assistant/brake pedal will work...

As said, I have never needed to for a cambelt change.

I have made a tool from an old pulley (old pulley with metal bar welded to it) for when I need to remove the lower cambelt pulley (i.e. to remove the oil pump or crank), but you simply use the gauge to find TDC and make sure it doesn't move while aligning your belt and tighten the cam pulleys (while using the cam blocks).
