1.8 TDCI Crank pulley tightening techniques

I'm lining up other jobs on the Focus once the current batch (transmission and front suspension) are done.

Quietly confident of managing renewal of the (upper) timing belt and tensioner. But crankshaft pulley looks like it's made of rust and also needs changing.

Bought a genuine Ford crankshaft bolt, and will probably use an INA crankshaft pulley as replacement. I've got the special timing tools too.

What is a concern is the tightening of the new crankshaft pulley bolt. 100nm + 180 degrees is super high torque on a car. 

So ... My question is: How to achieve this high torque? Welcome replies on tools and techniques from those members who have done it manually (i.e without impact driver).

P.S. Did a couple of subframe bolts required to be 280nm. Managed 200nm + c.30 degrees and could do no more (guessing / hoping this might be equivalent to c.280nm). 100nm + 180 degrees looks like more ...

    I'm a fan of the 3 foot breaker bar.

    Top tip for a 180 degree is to mark the bolt at the top then tighten in 2 or 3 actions, moving the bar back to a more manageable height each time.  When the mark is at the bottom it's complete.

    I have a short length of Scaffolding Pole that I can put over my Breaker Bar for extra leverage when necessary and there is room to use it. You do need strong Sockets though.

    Thanks Tom & Tizer. Guess I must have had 3 ft length when I did the subframe (part of a jack handle as extension). I maxed out at 200nm + 30 degrees but lying on my back so couldn't use any bodyweight.

    Main thing is that you both feel it is doable with a quality socket and at least a yard of length.

    What about techniques? Car will be on axle stands on the drive. I've seen one using 1-2 extension bars from socket to reach out to the breaker bar, and pivoting on an axle stand set at the height of the crankshaft bolt ...

    That sounds like a good Idea.
