I'm ready to put them back together and have a question. I'm wondering if anyone can give me the proper way to install the flywheel and get the nessesary torque specifications. Nothing im my manuel brakes this down. Any help would be appreciated.
Thx

If you didn't you'll have to set the engine at TDC and align the flywheel by the timing marks on it.Use the "X". The torque spec is 55-65 foot pounds.

It's pretty simple to jam the flywheel using the ring gear and some type of screwdriver or wedge. This prevents it from turning as you attack it with your torque wrench.
The trick is to sacrifice a 6 point socket for the job! Because the bolts that hold the flywheel to the crank have shallow heads it's easy to round the corners off as you try to tighten them. If you take the appropriate size socket and grind it dead flat on its end the likelihood of it slipping off the shallow bolt heads is much less.
I would torque in two steps to the final value using a logical torque sequence. Make sure the mating flanges and spotless when you mount the flywheel.
I don't know if they use locking tabs or Loctite (blue) these days...I remember locking tabs.
