BALANCING

When the pistons, rods and counterweights all weigh the same, the engine is balanced, we can do this for you at ASF. We use a Sunnen balancer at ASF Machine and can balance most rotating assemblies to less than .5 grams. Fully balanced engines generally run smoother, make more power, rev higher and last longer. A great way to visualize a balanced engine versus an unbalanced engine is as follows: imagine a beach ball blown up with air, imagine what it's like to roll it across the floor, smooth right. Now imagine one of those big balls with the weighted ball inside of it, remember how those roll?

They roll more eccentric, not smooth, now imagine a load like that on your engine's bearings....which would you rather have in your engine?
