Putting the alternator and fan back together.
The book says 43lb foot for the fam bolt. But my socket is a 3/4 inch drive snd my torque wrench 1/2 inch.
So how tight is 43lb foot?
Must have done it OK last time when I put the new fan on.

Best put the torque wrench in the vice and pull it to get the feel Of 43 lbs ft then using the same length bar you should get pretty near with your pull on the fan slightly tighter is better than a bit loose.

No much help now Steve, but I bought a 1/2inch up to 3/4inch adapter to use the big sockets on my 1/2inch torque wrench.

1/2 to 3/4 converters and vice versa  are cheap as chips and you will need it again

Well I ended up putting the torque wrench on the pulley end of the alternator and used a fixed socket wrench on the fan end. Turned the fixed wrench, and the torwue wrench acted as a wedge to stop the alternator and fan rolling. Seemed to get it well tight before the torque wrench clicked in.
Seemed to be tightening up nicely from fan end. Doubt it can be guaranteed to tighten both ends equally but I'm confident it'll be good.
