I bought a rebuilt long block 2.7L and have to put the parts from my old engine onto the new one. I removed the harmonic balancer from my old engine, now have to install it on the rebuilt engine. To do this, I have to buy some Miller Special Tools. Which ones I really need to install the harmonic balancer.
To replace the harmonic balancer (damper) it says that I need to use Special Tool 8179 (forcing screw) along with the nut and thrust bearing from 6792. The pictures I see of the 6792 look like it comes with it's own screw. Why can't I just use the screw that comes in the 6792 - is it a different thread size than the crank bolt, whereas the 8179 is the same? The 8179 appears to be larger on one end. Bottom line, do I really have to also buy the 8179 or is there a way to avoid it?
Thanks,
Rich

Rich; If you do this type of work fairly often, you can buy a set that comes with multiple thread sizes to fit nearly all crankshafts. It also comes with the bearing. I'm pretty sure that I got my set from Snap-On. But, if this is a one time shot, seems that you could rent what you need from one of the large chain parts stores. Or, you can devise your own. You'll need about a 4" long bolt of the correct thread and pitch (grade 8 so it doesn't break), a nut, and a large flat washer. Thread the nut nearly all the way to the head of the bolt, put the washer on. With the balancer started onto the crank, thread the bolt into the crank; Then start turning the nut against the flat washer until the balancer 'bottoms' out. A couple of love taps with a plastic dead blow hammer won't hurt.
