Look on the bottom of each weight. If you luck out, you will find a letter of the alphabet printed, or stamped on the weight. The letter "R" means the weight belongs on the right side. The letter " L" means the weight belongs on the left side. And the letter "C" means the weight belongs in the center. Remember, it's right or left as you look at your grandfather clock, notright or left from your grandfather's view. You can now hang your grandfather clock weights correctly, but be skeptical if you find hand written letters on the bottom of your weights. They may or may not be correct, so I would suggest that you read on just to make sure you get it right!

The "general rule" to use when hanging unmarked grandfather clock weights is generally applicable to most clocks. If your grandfather clock is equipped with a wood stick pendulum, hang the heaviest weight on the right side chime train as it needs more power to run all of the independant chime hammers. The other two equal and lighter weights should be placed in any order on the left side strike train and center time train. It seems there is always an exception to the rule, and here it is:

If your grandfather clock has a lyre pendulum with a pendulum bob of 6.5 inches in diameter or more, then place the lightest weight on the left side strike train, and the other two equal heavier weights on the center time train and the right side chime train in any order. Remember, it's right or left from your view towards the grandfather. Your grandfather clock repair problem of mixed up and out of order weights should now be solved!

The clock has a metal pendulum w/4" diameter bob. Have 1 heavy weight a 2 lighter weights (same weight). So do I place one of the lighter weights on the left and center and the heavier on the right?

On most clocks, yes. I assume you saw no markings. All you can do is try. If it was running before, it should run again. You also need to carefully check the balance of the case side to side and front to back as well and the horizontal plane.
