question for backyard mechanics

A buddy of mine just replaced the front main bearing seal in his old Sentra. As he was prepared to tighten the bolt of the crank down, the engine turns as he does. Not seeing any way to hold the pulley in place, he puts the car in 'Drive', but that doesn't help.
He calls to ask me if I know what to do, I don't.

How do you torque the crank bolt to 120lbs if the engine turns with you? Thanks.

My first thought is to pull the starter and jam something in the flywheel teeth, but better to ask here:

Thanks for the link. I passed it on to my buddy. I asked him where he got the torque values from, and he said the Chilton's manual. I guess the book did not mention how to tighten the crank down once it been apart.

They did in the old manuals under the "Basics" section.
The new crappy manuals skip the basic knowledge stuff, assuming (wrongly) that if your smart enough to take it apart, your smart enough to put it together.

In almost every car I have ever worked on, rear or front drive, there is a removable inspection cover for the flywheel, and a place to put a pin/breaker bar/old crap screwdriver you don't mind ruining, to prevent the engine from turning.
