There are a couple of ways to torque the MTX crank pulley and SHO Phoenix has a pretty good step by step on how to do it, but there isnt anything on there about hot to torque the ATX pulley. What i do is pretty simple and it works like a charm. Its not really a secret, i actually learned about it here on the forum, but it took lots of searching and reading before i came across it. There isnt a thread on it, just a post with a rough sketch of what to do. I figured i would take some pics and post them up.
Needed materials -
-1/2" drive torque wrench
-1/2" drive 19mm socket
-Large 3" C-clamp(very important that it be a "large" 3 inch clamp)
-Small section of hard wood(something that wont split under the clamps pressure)
First you want to get the pulley on the crank and tighten it down as much as possible with your ratchet. Leave the 19mm socket on the crank bolt so you know how far on to place the piece of wood without it interfering. What you want to do is to clamp the piece of wood to the pulley as shown in the pic. Your wood doesnt need to be as long as what i used, it just needs to be large enough to go across the pulley to give you a flat surface to clamp to.
Once you have the wood clamped down nice and tight you can then go ahead and attach your 1/2" drive torque wrench and start torqing it down. The way this works is the back side of the c-clamp will be pressed up againt the lower part of the motor and will keep the pulley completely stationary while you torque it down. This is why you need to make sure to use a large clamp. A small one will not make contact with the engine and instead start to lodge up against the timing cover.
This method does work on the MTX pulley too, but because the MTX pulleys backside isnt as wide as it front its a little more complicated to get the clamp on good and tight.
I've used this method on both of my SHOs(ATX & MTX) and doing it this way i can leave the car up on the jack stands and dont need anybody else helping me.
