Harmonic Balancer question...simple
Ok, first engine, approaching final build stage. How do I know when I have finished installing the harmonic balancer?
Till I can't turn the installation tool anymore?
Sorry I just don't know,
Thanks!

pretty much, yeah.
You want to coat the crank snout and the inside of the harmonic damper with oil or assembly lube to let it press in as easily as possible. also, make sure you run a tap though the crank bolt hole and that the threads of the bolts are all clean and lightly oiled when you do it.
this way, a smooth steady turning of the socket (or whatever you're using) will press the damper on. You'll feel a noticable "thump" or change in the force required to turn the wrench. I pull just a little more to make sure, but really very little force is needed. Combined with a visual inspection, this tells you that the damper is seated against the crank. Stop here, otherwise you might strip threads or something ugly.

Ok, thats where it seemed to be at last night.
Thing is there, is about, ohh I don't know, a mm or two between the collar on the balancer and the timing cover...if you know what I am talking about.
It makes sense to me that you wouldn't want them flush together as then the balancer would be constantly wearing against the oil seal in the timing cover, but I figured I should check.
Still sound good?

I was thinking about that...just hoping there was also a check against point.
I'll go measure the stock one tonight.
Thanks again guys.
Sometimes you just don't want a stupid question to end up costing you a whole lot more in time and money, ya know?

If the motor is apart mock up the water pump with gaskets and all and you can run a straight edge off the water pump pulley mount.
I've also used a dial indicator with a magnetic block and just run the damper in to the same verticle plane.
When you thinking about dampers the timing cover seal - It seals against the damper shaft. So incerting the damper farther doesn't make it seal better it just screws up the belt alignment.
